Revisiting Zinc Air Batteries: Solutions for Longer Lifetime
Zinc air batteries are promising owing to its high energy density, safety and low cost. In contrast to the primary system used widely as power sources for hearing aid, the insufficient lifetime of both zinc and air electrodes has limited the development of the secondary system. In this presentation the zinc electrode behavior is mainly focused on. The deterioration mode is examined by advanced analysis and the improved lifetime based on the solubility control of the zinc species is demonstrated.

Overview of Metal Air Batteries
Society will need energy storage that exceeds the limits of Li-ion batteries. Such a need drives investigation of alternative batteries including metal-air, in particular Li/Na/Zn/Mg-air because of their high theoretical specific energy. Recent experience has demonstrated that understanding the fundamental science underpinning the operation of these batteries is essential if we are to assess the viability of them as technologies, and if viable to realize their potential. The problems and current performance limitations of metal-air batteries, especially Li-air, will be considered. The recent advances in fundamental understanding will be discussed, as will the consequences of this understanding for the future prospects of metal-air batteries.

Visualization of Electrochemical Reactions in Battery Materials with X-ray Microscopy
In this talk, I will discuss examples of the visualization of phase transformations using a variety of modes within the general family of X-ray microscopy, tailored to suit the scales and phenomena to be probed, but focusing on single particles. Because thermodynamic pathways can be controlled by the presence of electrical potential, the harvesting of a sample from a cycled battery, while providing a useful preliminary insight, can lead to misleading results due to the relaxation of components into a different state that is more stable under open circuit conditions. Therefore, measurements performed during the electrochemical reaction will be leveraged in this discussion. The mechanisms of transformation will be related to their impact on material and architecture properties.

Combining Reversible Oxygen Charge Transfer and Li-Excess to achieve High Capacity Cathodes
The highest energy density cathode materials are currently found among the layered compounds based on Ni,Co and Mn, but achieving much more than 200mAh/g has become difficult. Two new ideas are promising to obtain substantially higher cathode capacity: 1) By using a substantial amount of Li-excess, cathodes can be made tolerant to metal disorder thereby enabling the use of a much larger group of transition metals, while achieving capacities well above 200 mAh/g. 2) Reversible redox process that take place on the oxygen ions rather than on the transition metal ions are now well established and can reduce the transition metal content of cathode compounds. I will explore the physics of both these new directions and demonstrate with several examples how they have enabled novel high-capacity cathodes.

Thick Electrode Designs for Lithium Ion Batteries
A typical lithium-ion cell contains about 25 individual materials layers per 1 mm of stack thickness, an evolutionary result after a quarter century of technology development that remains non-optimal from materials cost and volume utilization viewpoints. This talk will discuss recent work at MIT and 24M Technologies on thick electrode designs that can reduce materials cost from non-energy-storing components while delivering necessary electrochemical kinetics and remaining highly manufacturable. 24M has developed a new semisolid electrode technology and manufacturing method that yields electrodes with several times the thickness and area capacity of conventional lithium ion electrodes, yet has transport kinetics rapid enough for all but very high power applications. The semisolid lithium ion cells have significantly fewer inactive component layers than conventional lithium-ion cells of similar performance, and can be produced by a radically simpler process that obviates most of the electrode fabrication unit operations in conventional Li-ion, thereby lowering both materials and manufacturing cost. At MIT, magnetic alignment methods that produce low tortuosity porosity from sacrificial pore formers have been developed, that are rapid, scalable, and naturally produce aligned porosity favorably oriented normal to the electrode plane.

What is the Best Anode Material to Achieve High Energy Li-ion Batteries in Next 5 Years?
In spite of some technical advances in mitigating the volume-change problem toward the practical application of Si anodes, several challenges are still remained and should be resolved. First, the development of noble surface-coating methods and stable electrolytes for reducing the side reactions should be considered to stabilize the SEI of the Si anode. Although reducing methods of the HF derived from fluoroethylene carbonate (FEC), which is widely used in Si anodes to stabilize the SEI layer, is required because substantial capacity fading occurs as the HF attacks both the cathodes and Si. Second, in order to apply the Si anode to commercial LIBs and to achieve a high energy density, the change in the electrode thickness after tens of cycles should be examined in calendared Si anodes having an electrode density greater than 1.6 g cc-1, as an industrial standard. Based upon these requirements, I presents the best anode material, along with the real full cell test results.

The Role of Lithium Superoxide in Li-O2 Batteries
There has been much interest in rechargeable aprotic lithium-oxygen (Li-O2) batteries because their energy density can be significantly higher than that of the conventional Li-ion batteries. However, many challenges remain for Li-O2 batteries before they can become a reality. Understanding the growth and nucleation mechanisms of the discharge product is one of the keys to addressing these challenges because it controls the resulting morphology and composition of the discharge product. The efficiency and reversibility are dependent on the type of morphology and composition that is formed during discharge. In this paper experimental and computational results will be reported that have shed light on the growth and nucleation mechanism in Li-O2 batteries. Specifically, the role of lithium superoxide (LiO2) in the nucleation and growth mechanism during discharge and how to suppress the disproportionation reaction of LiO2 to lithium peroxide (Li2O2) will be discussed. The implications of these new results for reducing charge overpotentials in Li-O2 batteries and in the design of new cathode materials will be discussed.

Electrolytes without Ethylene Carbonate for High Voltage NMC/Graphite Li-Ion Cells
Ethylene carbonate is used in virtually every lithium-ion cell. In efforts to produce high voltage NMC/graphite cells, electrolytes without ethylene carbonate are being explored. The use of electrolytes based on fluoroethylene carbonate (FEC), difluoroethylene carbonate (di-FEC), bis(2,2,2-trifluoroethyl) carbonate (TFEC) and other solvents are explored in this presentation. Studies using ultra high precision coulometry, impedance spectroscopy, isothermal battery microcalorimetry, in-situ gas evolution, storage testing, XPS and long-term charge-discharge testing show the benefits and drawbacks of such electrolytes. Although progress is being made, there remains substantial work to do to produce high energy denisty NMC/graphite cells which can operate for years to 4.5 V. This work was done by Jian Xia, Remi Petibon, Steven Glazier, Kathlyne Nelson, Dan Abarbanel, Deijun Xiong, Leah Ellis and Alex Louli.

The Intriguiging Question of Anionic Redox in High-Energy Density Cathodes for Li-ion Batteries
The energy density delivered by a Li-ion battery is a key parameter that needs to be significantly increased to address the global question of energy storage for the next 40 years. This quantity is difficult to improve when materials exhibit a classical cationic redox activity.
Recently, a cumulative cationic (M4+/M5+) and anionic (2O2-/(O2)n-) redox activity has been demonstrated in the Li-rich Li2MO3 family of compounds, therefore enabling doubling the energy density with respect to high-potential cathodes such as transition metal phosphates and sulfates.
This paper aims at clarifying the origin of this extra capacity by addressing some fundamental questions regarding reversible anionic redox in high-potential electrodes for Li-ion batteries. First, the ability of the system to stabilize the oxygen holes generated by Li-removal and to achieve a reversible oxo- to peroxo-like (2O2-/(O2)n-) transformation is elucidated by means of a metal-driven reductive coupling mechanism. The penchant of the system for undergoing this reversible anionic redox or releasing O2 gas is then discussed in regards to experimental results for 3d- and 4d-based Li2MO3 phases.
Robust indicators are built as tools to predict which materials in the Li-rich TM-oxides family will undergo efficient and reversible anionic redox. The present finding provides insights into new directions to be explored for the development of high-energy density materials for Li-ion batteries.

Silicon and its Challenging Interfaces
Some silicon is now introduced into graphite electrodes (up to 7%) used in commercial lithium-ion batteries. To increase this amount further requires a profound understanding of the complex reactions taking place forming the SEI (the electrode/electrolyte interface) but also of the interface reactions taking place between the SEI and the bulk material. This presentation will discuss the implications of how the different kinds of interfaces will influence the reactions with lithium. It will also give a suggestion on how it is possible to make electrodes with a larger portion of silicon.

Fundamental Aspects of Lithium Ion Battery Materials Degradation Mechanisms
Increasing cycle-life and energy density of lithium ion batteries requires the development of improved electrolyte additives and a detailed understanding of the stability of electrolyte and cathode electrode components, particularly at high anodic potentials. The fundamental decomposition/degradation mechanisms will be examined by on-line electrochemical mass spectrometry (OEMS), by AC impedance, and by ex-situ ATR-FTIR and NMR. In this presentation, we will discuss the following aspects:
- anodic and cathodic decomposition mechanisms of electrolytes and electrolyte additives;
- quantification of the anodic stability of conductive carbons and of conductive carbon coatings at potentials relevant for high-voltage cathode materials;
- effect of water and hydroxide impurities on carbon and electrolyte stability.

NMR Beyond Li: New Approaches in Studying Na, Mg and Li-air Batteries
This talk will describe the use of NMR spectroscopy to characterize a series of “beyond-Li” electrode materials. The NMR results are combined with complementary techniques such as pair distribution function analysis of (X-ray) scattering data. In the sodium-ion battery case, 23Na NMR spectroscopy can be used to follow changes in local structure in a manner very similar to that performed on lithium-ion battery materials. Our work using the method to study local structure and Na+ and electronic ordering in positive layered materials and intermetallic anodes will be described. 25Mg NMR is more challenging, but the use of DFT calculations to predict shift positions and help interpret the spectra speeds up the analysis considerably. This will be illustrated for paramagnetic positive electrode materials. The use of NMR and MRI (magnetic resonance imaging) to link structural changes with electrolyte concentrations will be demonstrated for lithium metal anodes. Finally, new developments in the field of lithium-oxygen batteries will be described. In particular NMR spectroscopy allows the different discharge products and many side-reactions to be followed. For example, 1H and 7Li NMR spectroscopy can be used to separate Li2O2 from LiOH, allowing the formation and removal of LiOH to be quantified. Our recent studies with LiI redox mediators and r-GO electrodes will be described.

US DOE Electric Vehicle Battery R&D Progress and Plans
The Department of Energy’s Vehicle Technology Office (DOE-VTO) funds high-reward/high-risk research conducted by national laboratories, universities, and industry – to develop low-cost and high-performance automotive batteries necessary for the consumer acceptance of hybrid and plug-in electric vehicles (PEV) in the marketplace. In fiscal year 2015, VTO battery R&D funding totaled about $80 million. Current battery technology performance is far below its theoretically possible limit and in the near-term, opportunity exists to more than double the battery pack specific energy for lithium-ion technology by using new high-capacity cathode materials, higher voltage electrolytes, and by replacing graphite anodes with high capacity silicon or tin-based intermetallic alloys. In the longer term, certain “beyond Li-ion” battery chemistries) offer the possibility of specific energy values significantly higher than those of current lithium-ion batteries as well as the potential of significantly-reduced battery cost. Despite recent promising advances, more R&D is needed to achieve the requisite performance, lifetime and reduced cost needed for these new battery technologies to enter the market. The status of VTO-funded advanced automotive battery R&D projects for FY 2014-15 will be discussed in this talk and associated issues will be highlighted.

Development of Sodium-Ion Batteries for Grid-Scale Energy Storage
With the tremendous development of renewable energies such as solar and wind powers, the smooth integration of their energies into the grid, thus improving the grid reliability and utilization, critically needs large-scale energy storage systems with low cost, long-life, high efficiency and high safety. Among the various energy storage technologies, electrochemical approach represents one of the most promising means to store the electricity in large-scale because of the flexibility, high energy conversion efficiency and simple maintenance. Due to the highest energy density among practical rechargeable batteries, lithium-ion batteries have been widely used in the portable electronic devices and would undoubtedly be the best choice for the electric vehicles. However, the rarity and non-uniform distribution of lithium in the Earth’s crust may not simultaneously support these two important application areas: electric vehicles and renewable energy. In this regard, room-temperature sodium-ion batteries with lower energy density compared with lithium-ion batteries have been reconsidered particularly for renewable energy, where cost and cycle life are more critical factors than energy density owing to the abundant sodium resources (2.75%) and low cost as well as similar “rocking-chair” sodium storage mechanism as lithium. More importantly, we can use Na+ ions as the charge carrier to explore new chemistry and new materials to further decrease the cost. For example, sodium cannot form the alloy with aluminum, therefore aluminum foil can be used as the current collector for the anode without the overdischarge problem.
In this talk, I will present our recent research progress on the sodium-ion batteries from IoP-CAS. In particular, I will focus on a series of air-stable and Ni-/Co-free Na-Cu-Fe-Mn-O (e.g., Na0.9Cu0.2Fe0.3Mn0.5O2) cathode and a superior low cost amorphous carbon anode made from pitch and lignin. Finally, the prototype sodium-ion batteries based on these cathode and anode materials will also be demonstrated to have promising practical application.

Highly Concentrated Electrolyte for 5 V Systems
Highly concentrated electrolytes have many unique properties, and all solvent molecules are strongly coordinated with Li+ ions, and hence the stability of the electrolytes against oxidation is improved significantly. 5-V cathodes, e.g. LiNi0.5Mn1.5O4, are promising for the next-generation LIBs with high energy densities. Unfortunately no electrolyte systems that tolerate the highly oxidative 5 V cathode have been reported so far. In the present study, we investigated the effect of concentration on the stability of highly concentrated electrolytes, LiPF6/PC and LiBF4/PC, against a 5-V cathode, LiNi0.5Mn1.5O4 to realize 5 V LIB systems.

"Solidifying” Batteries – Solid Electrolytes in Lithium (Ion) Batteries
Solid electrolytes and solid state batteries are currently attracting serious interest as potential future components and storage devices. Solid electrolytes (polymer, ceramic or composites) are required to construct protected lithium anodes – in case that lithium metal anodes will become again part of lithium batteries. If the cathode is still employed in contact with a liquid electrolyte, a new interface between a liquid and a solid electrolyte forms which can be highly resistive. Solid state batteries without any liquid electrolytes are considered as ultimately stable and safe devices, but are expected to suffer from poor kinetics and high costs. The lecture will include answers to the following questions:
- Are solid electrolytes necessarily worse lithium ion conductors than liquid electrolytes?
- Are solid electrolytes the key to ultimately long-term stable batteries?
- What do we know about the interface between liquid and solid electrolytes?
- What is the state of the art thin film battery?
- How to construct “thick film” solid state batteries?
- Important research tasks in the development of solid state batteries?

Developments of Lithium Solid Electrolytes and their Application to all Solid-state Batteries
Lithium solid electrolytes promise the potential to replace organic liquid electrolytes and thereby improve safety of the next-generation batteries. Among the electrolytes proposed, the sulphide system is a candidate for practical batteries because of their high ionic conductivity; the Li10GeP2S12 (LGPS) phase exhibits high ionic conductivity of over 10-2 S cm-1 at room temperature and is promising for applications requiring batteries with high powers and energy densities. The present study focuses on several topics of the all solid-state system using the inorganic electrolytes. (i) Material varieties of the LGPS system may provide suitable combinations of the electrodes and the electrolyte. To improve the materials variety, the substitution systems with the LGPS type structure were examined, and their phase diagram, structure and ionic conduction were studied. (ii) The combination with high-voltage electrode or high-capacity electrode may provide high capacity systems. The all solid-state batteries using various electrode materials were examined. (iii) The reaction at the electrolyte/electrode interface is the important issue to improve the stability and rate capabilities. High resistance at the interface of the solid-state system might prevent their usage for high current battery systems. Reactions at the interface were also examined. Based on these experimental results, the battery characteristics of the all solid-state system using LGPS electrolytes will be discussed.

Ecological Friendly Recycling of Lithium Ion Batteries – the Lithorec Process
The increasing demand of lithium ion batteries requires the recovery of active materials from spent lithium ion batteries and production rejects in order to prevent a future shortage of lithium and other valuable raw materials. In contrast to existing recycling processes, the main goal of the LithoRec process is to achieve a high recycling yield and a low ecological impact as well as to efficiently recover all battery materials at battery grade quality. The project spams the entire recycling process starting from the discharging and disassembly stages, and following through with mechanical, chemical and thermal processing (e.g. crushing, grinding, classification, sorting, and extraction) used to separate the battery into recyclable fractions. In order to match the high purity standards of hydro-metallurgical processes for the production of battery active materials, the battery active materials have to be separated from the current collector foil very purely. For that purpose, a new patented separation process has been developed which show a very high separation rate at high purity. The entire process was set up in pilot scale and operated with spent different spent battery systems. Results of this pilot trials will be discussed in the paper. Subsequently, new battery active materials have been produced and characterized in battery test cells.

Technology improvements are necessary that allow the transition towards mobility concepts based on renewable energies. Today the electrification of drive trains, ranging from hybrid vehicles to plug-in hybrids, and finally to pure electric vehicles, is the commonly accepted next step in this direction. BMW is strongly committed to this path.
The electric energy storage is the key technology for electrification. Energy and/or power density of the storage system define the fuel reduction potential as well as the customer acceptance. To make it a success story, care has to be taken to fulfill the present and future customer expectations, in particular with regard to safety and reliability, performance and costs. One of the major factors for a high market penetration of electric vehicles is the ratio between driving range and costs. More than 90% of the world wide vehicle market falls in the price range below 50.000$; on the other hand, a driving range above 400 km is needed. That requires energy density targets above 250 Wh/kg or 400 Wh/l for a battery pack, with costs as low as 150 $/kWh.
Different strategies are nowadays considered which enable a considerable increase in the electric range. These include the optimization of cell and electrode design. But the largest impact on the energy density is the introduction of novel cathode and anode materials for Li-ion cells. There are a number of materials in development which may give an improvement in energy density. But only a few seem to have the potential to meet automotive requirements in particular regarding lifetime and safety. For most of the material developments considerable improvements are needed before a possible industrialization of the new generations of batteries for automotive application can be envisaged.
This presentation will outline the potential and limits of present material concepts from a car manufacturer point of view. In particular it will address open issues to be solved in the future development of electric energy storage technologies for automotive applications.

Lithium- and Sodium-sulfur Cells with High Sulfur Loading
Lithium-sulfur (Li-S) and sodium-sulfur (Na-S) batteries are promising candidates as the next-generation energy-storage systems because of the high charge-storage capacity, natural abundance, and environmental friendliness of sulfur. However, the practical utility of Li-S and Na-S cells is hampered by low electrochemical utilization of sulfur and severe polysulfide diffusion, resulting in low discharge capacity and poor cycle life. Efforts to overcome the persistent problems often result in low-sulfur-loading cathodes, defeating the purpose of Li-S and Na-S cells replacing the current lithium-ion technology. Recognizing that the traditional cathode configuration borrowed from commercial insertion-compound cathodes may not allow the pure sulfur cathode to put its unique materials chemistry to good use or reach high active-material loading, this presentation will focus on unique approaches in engineering the sulfur cathodes with active material loading as high as 10 mg/cm2. For instance, binder-free layer-by-layer sulfur cathodes as well as omurice-type electrodes, supporting high sulfur loading, long life, and high gravimetric, volumetric, and areal capacities, will be presented. In addition, the use of solid electrolyte membranes to suppress polysulfide migration and alkali-metal dendrite growth will be presented.

Ion Solvation Effects in the Nonaqueous Li-O2 Electrochemistry
Multiple directions in battery research are now being pursued in hopes of advancing beyond the specific energy limits imposed by conventional Li-ion electrode materials. For example, ‘beyond Li-ion’ battery chemistries, such as Li-O2, Li-S, and Mg-ion, are currently being explored as potential successors to Li-ion batteries given their very high theoretical specific energies; yet severe technical challenges have prohibited them from becoming a practical reality. The objective of this presentation is to provide an assessment of such challenges, in particular, instabilities of the electrolyte and cathode, and Li2O2 electronic conductivity limitations, facing the nonaqueous Li-O2 battery cathode. Results will be presented on the characterization of the Li2O2 formation mechanism and how the mechanism can be manipulated through electrolyte engineering to potentially alleviate problems associated with Li2O2 deposition on the cathode.

Making the Invisible Visible – Advanced Diagnosis Methods for Lithium Ion Rechargeable Battery Materials
Scanning electron microscopy and electron energy loss spectroscopy (STEM/EELS) offers unprecedented spatial resolution, which has enabled nanoscale imaging and chemical analysis of battery materials - their surfaces, grain boundaries and phase boundaries. Combining the state-of-the-art in situ operando analytical electron microscopy with first principles (FP) computational data analysis, we reveal some insights that could not be possible to see in the past. On the other hand coherent x-ray diffractive imaging (CXDI), a lensless form of microscopy capable of discerning electron density and strain with 20 nm resolution, can be used to map the strain evolution of a single cathode particle in a functional battery material as it is cycled in-situ. The evolution of compressive/tensile strain reveals a number of interesting phenomena. For instance, strain can be quantitatively correlated to the Lithium amount in the initial cycles, eventually becoming uncorrelated upon long-term cycling. We demonstrate that CXDI is a powerful diagnostic tool to reveal correlation between strain and electrochemistry at the single particle level and offers valuable information for electrode/battery modeling and future battery design. By combining electron based and X-ray based novel imaging techniques, we showcase the state-of-the-art diagnostic tools developed for probing functional battery materials in operando.

Suppression of Polysulfide Transfer by Polypyrrole Modification on Cathode in Lithium-Sulfur Battery
The issues to realize the Li-S battery includes dissolution of polysulfide generated during the charge-discharge operation of cathode. The dissolved polysulfide inside the battery leads chemical shortage between the cathode and the anode. Electrochemically active polymers such as electropolymerized polymer films have a feature of ion-exchange ability as well as perm-selectivity of ions transferring in the film. Polypyrrole which is formed on the S cathode and is containing soft anion by electropolymerization stops the flux of polysulfide and enables improved cycle performance. Battery performance of Polypyrrole coated S cathode will be introduced.

A Reality Check on Battery Materials Development
The demand for cost-effective rechargeable batteries with high gravimetric and volumetric energy density will continue to grow due to the rapidly increasing integration of renewable energy into the global energy scheme. In terms of energy density, modern high-end rechargeable battery technology is reaching its fundamental limits, and no quantum leaps are expected in the advancement of the field in the foreseeable future. We describe here an energy-cost model we have developed for making a comparative evaluation of battery-cell chemistries. Among the wide variety of positive electrode materials available, only a few have sufficient potential to justify commercialization. Clearly, the immediate future will continue to be dominated by Li-ion technology. Given this scenario, this talk addresses the question as to which material types have a realistic chance of actually making it in the battery market-place.

Conversion-alloying Anode Materials for Lithium-ion Batteries
Lithium-ion batteries, the most successful power source for portable electronic devices, are emerging as the most promising energy storage devices for hybrid and, most likely, full electric vehicles. In our continuous efforts to develop high capacity, conversion-alloying anode materials for lithium-ion batteries, we developed a new active material, Fe-doped SnO2 (Sn0.9Fe0.1O2, SFO), ideally characterized by low (de-)lithiation potential, high coulombic efficiency and long-term cycling stability. To the best of our knowledge, this is the first report on iron-doped tin oxide as active material for lithium-ion batteries. For battery applications, however, only one manuscript dealing with the utilization of molybdenum-doped SnO2 as active material for lithium-ion batteries was reported in 1999, i.e., prior to the first report on transition metal oxides as conversion materials by Poizot et al. in 2000.
Within this study it is shown as doping SnO2 with Fe leads to significantly enhanced specific capacity, cycling stability, and coulombic efficiency. SFO-C offers, after ten cycles, a reversible specific capacity of 1519 mAh g-1, i.e., about twice that of pure SnO2, due to the presence of the dopant (Fe) favoring the reversible formation of lithium oxide and, thus, enabling the beneficial combination of lithium storage by alloying and conversion

Oxygen Electrochemistry in Aprotic Li-Air Batteries
As a promising candidate for next generation energy storage system, Li-air battery has generated a great deal of interest over the past decade. However, realization of the practical Li-air battery is a formidable challenge, and is impeded by some fundamental key issues including the degraded capacity, limited cycle life, notoriously low round-trip efficiency and limited stability of battery components, which are currently being tackled by numerous approaches. From the viewpoint of fundamental study, a better understanding of the oxygen electrode reactions in aprotic electrolyte will be beneficial to the realization of Li-air batteries with improved electrochemical performances. Here, a mechanistic study of oxygen electrochemistry in aprotic Li+ electrolyte has been conducted using Raman spectroelectrochemistry coupled with density functional theory calculations. By spectroscopic identification of oxygen intermediates under various operating conditions, different routes for Li2O2 formation have been revealed.

Silicon Foam Anode with Stabilized Interface for Lithium-ion Batteries
Silicon has been regarded as an optimized anode material of LIBs due to its low discharge potential and high specific capacity. Challenges from the huge volume change during the alloying reaction of silicon with lithium still obstacle the application of silicon anode, since the huge volume change causes particle pulverization, electrode disintegration and the solid electrolyte interphase (SEI) film ceaseless growth. Although some nano-structured silicon anode materials, such as hollow nanospheres, silicon core-hollow carbon shell nanocomposites, 1D hollow silicon nanotubes, showed the improved cycle performance. However, the ceaseless growth of SEI film is still absence of evidence. In this work, we report a facile approach to prepare silicon foam with hollow structure with a chemical vapor deposition (CVD). With the built-in space, this silicon foam presents remarkable capacity retention and fairly high coulombic efficiency. The method combining the electrochemical impedance spectroscopy with differential scanning calorimetry (DSC) to elucidate the SEI stability was developed, which confirm that silicon foam have more stabilized interface.

Probing Reactivity at the Electrode and Electrolyte Interface
Understanding reactions at the electrode/electrolyte interface (EEI) is essential to developing strategies to enhance cycle life and safety of lithium batteries. There is limited understanding by what means different components are formed at the EEI and how they influence EEI layer properties for positive electrodes. High-capacity layered oxides, which can generate highly reactive species toward the electrolyte via oxygen anion redox, highlight the critical need to understand reactions with the electrolyte and EEI layers for advanced positive electrodes.

Advanced Cathode Material with Full Concentration Gradient for High Energy Density Lithium- and Sodium-ion Batteries
Rechargeable lithium- and sodium-ion batteries have great potential as a new large-scale power source for electric vehicles (EVs) and energy storage system due to their high energy density, high voltage, and long cycle life. However, commercialization of these batteries for the automobile and energy storage industries requires further improvements in energy density and safety. Here, we report a novel cathode material with concentration gradient of Ni, Co, and Mn ions throughout each secondary particle where the nickel concentration decreases linearly whereas the manganese concentration increases linearly from the centre to the outer layer of each particle. Using this functional full-gradient approach, we are able to harness the high energy density of the nickel-rich core and the high thermal stability and long life of the manganese-rich outer layers.

Ab-initio MD Simulations of Redox Reactions of Liquid Electrolytes and SEI Formation
Atomistic understanding of solid electrolyte interphase (SEI) formed at the interface between electrode and liquid electrolyte is still an issue of great importance. However, difficulties in experimental in-situ observations of the buried interfaces and simulations considering the liquid dynamics (fluctuation) and reaction have inhibited the progress of elucidation. We have addressed such issues by means of accurate large-scale ab-initio molecular dynamics (MD) samplings and free energy calculations on a huge supercomputer. In this talk, we will introduce our recent findings of (i) a novel role of vinylene carbonate additive on reductive decomposition of ethylene carbonate electrolyte, (ii) a novel formation mechanism of organic SEI components with near-shore aggregation, and (iii) their extensions to different electrolytes. These ab-initio studies on the atomic scale will provide a new microscopic perspective of SEI.

“Water-in-Salt” Electrolyte Enabled High Voltage Aqueous Li-ion Chemistries
The application of Li-ion batteries for vehicle-electrification and grid-storage is deterred by their safety, environmental and cost concerns, which are mainly imparted from the non-aqueous electrolytes used therein. These obstacles could be circumvented by an aqueous alternative; however, narrow electrochemical stability window (1.23 V) of the latter, imposed by hydrogen and oxygen evolutions at anode and cathode, respectively, sets an intrinsic limit on the practical voltage and energy output of an aqueous Li-ion cell. Here, we report a new aqueous electrolyte, whose electrochemical stability window was expanded to ~3.0 V via super-concentration and concomitant interphasial chemistry. A full Li-ion battery of 2.3 V was demonstrated to cycle over 1000 times in this electrolyte, with nearly 100% Coulombic efficiency at both low (0.15 C) and high (4.5 C) rates. For the first time, breaking Pourbaix-limits makes it possible for an aqueous Li-ion chemistry to deliver energy density over 100Wh/kg.

Glyme-Li Salt Solvate Ionic Liquids for Advanced Lithium Batteries
Certain molten complexes of Li salts and solvents can be regarded as ionic liquids. In this study, the local structure of Li+ ions in equimolar mixtures ([Li(glyme)]X) of glymes (G3:triglyme and G4: tetraglyme) and different Li salts was investigated to discriminate between solvate ionic liquids and concentrated solutions. Raman spectroscopic analysis allowed us to estimate the fraction of the free glyme in [Li(glyme)]X. The amount of free glyme was estimated to be a few percent in [Li(glyme)]X with perfluorosulfonylamide-type anions, and thereby could be regarded as solvate ionic liquids. Other equimolar mixtures of [Li(glyme)]X were found to contain a considerable amount of free glyme, and they were categorized as traditional concentrated solutions. The activity of Li+ in the glyme-Li salt mixtures was also evaluated by measuring the electrode potential of Li/Li+ as a function of concentration. At a higher concentration of Li salt, the amount of free glyme diminished in the solvate ionic liquids, leading to a drastic increase in the electrode potential. Unlike conventional electrolytes (dilute and concentrated solutions), the solvation of Li+ by the glyme forms stable and discrete solvate ions ([Li(glyme)]+) in the solvate ionic liquids. This anomalous Li+ solvation had a great impact on the electrolyte properties and electrode reactions, which enhanced the utility of the solvate ionic liquids in advanced lithium batteries such as Li-S batteries

Electrolyte Additives - How do They Work and Why are They Efficient?
State of the art electrolyte formulations nowadays still meet challenges to fulfill the increasing demands of special applications. Electrolytes for 5V applications, with inherent safety features like non-flammability and overcharge protection as well as enhanced cycle life are the focus of worldwide research. Chemistry of liquid electrolytes and their interaction with anode and cathode materials is complex and yet not fully understood representing the delicate balance of various properties. One of the promising solutions is the application of electrolyte additives, added in small amounts to the electrolyte formulation to improve the demanded properties.
Although different electrolyte additives have found their application in improving the electrolyte performance not much is understood about their role and efficiency. Since an electrolyte has a complex starting composition consisting of inorganic fluorinated salts, organic solvents and additives analytical and electrochemical techniques have to be developed and applied for the numerous individual species that are present in the system. By means of developed analysis methods, decomposition products can be evaluated to determine operation and failure mechanisms.

Polymeric Electrode Modification for Enhanced Performances of Li-Ion Batteries
The properties of the interface between electrode active materials and electrolyte have profound effects on the performance of Li-ion batteries (LIBs). A large amount of research has so far been devoted to modifying the surfaces of active materials in order to enhance the overall performance of the electrodes. Majority of the research has resorted to inorganic oxide coatings, presumably due to their chemical stability, and different beneficial effects have been claimed for both cathode and anode materials. There have relatively been far fewer studies on polymeric coating. The rich chemistry of polymeric blend intrinsically provides great flexibility for dealing with wide varieties of active materials and electrolytes for maximum performance. In this presentation, several examples using designed polymeric blend coatings on various LIB electrodes, including graphite and Si anodes and a NCM cathode, to substantially enhanced electrode capacity, rate performance and/or high-temperature cycle stability will be presented.

Concentrated Liquid Electrolytes
Ever-increasing demand for better batteries has set extraordinarily high standards for electrolyte materials, which are far beyond the realm of a conventional electrolyte design. Superconcentrated (or highly concentrated) solutions are emerging as a new “realistic” class of electrolytes with various unusual functionalities beneficial for advanced battery applications. In this invited contribution, we will introduce our original technical achievements towards (i) versatile salt/solution combination, (ii) ultra high-rate reaction, (iii) high voltage operation over 5 V, iv) corrosion/dissolution prevention, (v) extreme safety, and (vi) advanced high-voltage aqueous energy storage systems, none of which were realized by the conventional electrolytes. Several unique inherent features, as well as the fundamental physicochemical properties, underneath the surprisingly superior battery performance realized by concentrated liquid electrolytes, will be analyzed from the viewpoint of their peculiar solution structure, providing the firm design considerations toward better batteries.

Understanding the Anomalously High Capacity of Li- and Mn-Rich Cathodes for Li-Ion Batteries
The reaction mechanism of a high capacity lithium- and manganese-rich metal oxide has been investigated. High-resolution synchrotron X-ray powder diffraction (HRPD) and X-ray absorption spectroscopy (XAS) were used, respectively, to evaluate the electrochemical charge and discharge reactions in terms of local and bulk structural changes, and variations in the oxidation states of the transition metal ions. Ni K-edge XAS data indicate the participation of nickel in reversible redox reactions, whereas Mn K-edge absorption spectra show that the manganese ions do not participate in the electrochemical reactions. Rietveld refinements of the oxygen occupancy during charge and discharge provide evidence of reversible oxygen contribution by the host structure; this unique oxygen participation is likely the main reason for the anomalously high capacity of these electrodes. The HRPD data also show that during the early cycles, characteristic peaks of the Li2MnO3 component disappear when charged to 4.7 V, but reappear on discharge to 2.5 V, consistent with a reversible lithium and oxygen extraction process. The results provide new insights into the charge compensation mechanisms that occur when high capacity, lithium- and manganese-rich electrode materials are electrochemically cycled – a topic that is currently being hotly debated in the literature.

Stable Operation of Li Metal Anode for Rechargeable Batteries
Rechargeable Li metal batteries are considered the “holy grail” of energy storage systems. However, dendritic metal growth and limited Coulombic efficiency (CE) during Li deposition/stripping have prevented their applications in rechargeable batteries. In this work, we will report several approaches to suppress Li dendrite growth and enhance the CE of Li deposition/stripping. New electrolyte compositions based on high concentration electrolytes and additives will be discussed. We will also demonstrate that the dendrite growth and CE of Li deposition is strongly depends on both charge and discharge protocols. Combination of stable electrolyte and appropriate operating protocols can largely suppress dendrite growth and lead to long term stable operation of Li metal batteries.

Ceramic Interface (Ceramic Coated Separator) and Li-Ion Safety/Performance
One of the great innovations in Li-ion batteries: ceramic interface via ceramic coated separator made the transition of its polymer based separator to ceramic coated (interface) separators during the last a couple of years. Nearly 90% Li-ion batteries in consumer electronics and 2nd generation EDV are using ceramic coated separators today. This ceramic interface via ceramic coated separator greatly enhanced Li-ion energy density (reduced oxidation of separators that enable the use of high voltage cathodes), greatly improved battery safety (reduce the thermal propagation to avoid serious thermal runaway) and battery life (ceramic react with oxidized electrolytes, H2O and HF that continuously purifies the electrolyte). The development, mechanism, specific ceramic interfaces and battery results will be presented and discussed.
