The production of electrodes for all solid state batteries depends on the kind of solid electrolyte. As for solid polymers still slurry based processes can be applied, solid particle based electrolytes need new concepts for electrode production. Examples
are extrusion or dry coating processes with subsequent consolidation for deformable electrolytes or high temperature sintering for ceramic electrolytes.

14:20 An Industrial View on Challenges of Solid Electrolytes for Solid State Batteries
Andreas Roters, Ph.D., Senior Project Manager New Venture, Research and Deveolpment, SCHOTT AG
Solid electrolytes are a key material to enable solid-state batteries. From the viewpoint of an industrial material development, the main challenges are the appropriate design of the interface to enable a low resistant Li-ion transport on material
level. For the integration into a cell, systems material and processing solutions must be found which allow Li transport on one side, but hinders side reactions of the material during processing at the other side. Stable and cost-effective processing
routes from raw material and high-volume production to recycling. Glass ceramics have the potential to address these challenges.

8:35 Electrolytes and Electrode Interphases in Lithium-Ion Batteries
Brett Lucht, Ph.D., Professor, Chemistry, University of Rhode Island
During the initial formation cycles, a Solid Electrolyte Interphase (SEI) is formed on the anodes of lithium ion batteries which is critical to the performance of lithium ion batteries. The electrolyte also reacts with the surface of the cathode,
especially at high voltage, to generate a surface film. The nature of the electrolyte and the electrode surface films and the role they play in performance of lithium ion batteries will be presented.
8:55 Development of Novel Electrolyte Formulations for Use with High-Energy Cathodes
Dee Strand, Ph.D., CSO, Chemistry, Wildcat Discovery Technologies
Higher energy cathodes are required to meet automotive energy density targets. However, the use of these materials (higher nickel content, higher voltage) require parallel development of electrolytes with enhanced stability. Electrolyte additives
that provided enhanced stability on the cathode need to be compatible with other formulation components, requiring significant development efforts. This presentation demonstrates the challenges and shows examples of improved electrolyte formulations.

15:05 Next Generation Low Weight Lithium Sulfur Batteries
Stefan Kaskel, Ph.D., Professor, Department of Chemistry, Technical University Dresden, Fraunhofer Institute Materials and Beam Technology
Lithium sulfur batteries are among the lightest accumulators today for applications in aviation and for high altitude pseudosatellites. However, their cycling stability is limited due to the use of elemental lithium as anode. Recent research
focuses on alternative anode materials, such as silicon nanocomposites and thin films, and improved processing of thin lithium foils by melt processing. New anode processing technologies may also play a key role for solid state batteries
in future.
15:45 Post and Beyond Lithium-Ion Materials and Cells for Electrochemical Energy Storage
Andreas Hintennach, Ph.D., Group Research Electrochemistry, Mercedes-Benz Research & Development, Daimler AG
Novel and sustainable electroactive materials can help to decrease the ecological impact of novel battery concepts in the near future. While on the one hand high energy density is required, the aspects of safety, lifetime get more important
and often mean a challenge. All these requirements are met by very different approaches with different characteristics: all solid-state cells, high-energy materials, lithium-sulfur and even different systems e. g. Na- or Mg-Ion.
16:05 Developing High-Energy Rechargeable Lithium Metal and Lithium Sulfur Batteries
Jun Liu, Ph.D., Director, Energy Processes and MaterialsPacific Northwest National Laboratory
Energy storage is critical for grid modernization and electrification of transportation infrastructure. Among many options, two battery systems are identified to have the potential to reach a much higher energy density: Li metal anode
coupled with high Ni NMC, and Li-S system. However, the materials and components need to be optimized to allow high-efficiency utilization of the active materials (high utilization). For both NMC and Li-S
systems, several new approaches will be discussed to address the challenges in the high energy cells. Under high-utilization conditions, the fundamental failure mechanisms may also differ from the experimental conditions widely studied
in the literature and will also be discussed.

Fanny Bardé, Ph.D., Project Manager, Toyota Motor Europe
Achieving mobility for all is one of the main challenges of this century and is the “raison d’être” of Toyota company. In view to achieve sustainable mobility combined with zero emission society, Toyota is envisioning
several answers from eco-car models to a smart mobility society model, keeping in mind the satisfaction of its customer. The non-aqueous Li-Air (Oxygen) battery, because of its high theoretical energy density and relatively high operation
voltage around 3V gives the promise of long driving range for future electric cars, which is a key factor to get accepted widely by our customers. Nevertheless, it suffers from some scientific hurdles to overcome, before this battery
concept can be commercialized. In this presentation, we will summarized over 8 years of advanced research performed in the Toyota group on the Li-Air(Oxygen) battery, before to share some perspectives for this promising but challenging
battery type.
