Overview of the current next-gen (silicon and lithium metal anode) trends both in the West as in China. Reality check of the status of these techs/companies, focusing on both the advantages and potential limitations. Forecast of when these products could be online and the risk for displacement of the current ones (e.g., graphite).

Solid-state battery cells, with their superior energy density compared to the conventional lithium-ion technology promise very long driving ranges in future electric vehicles.In this publication, a premium battery with a lithium metal anode cell and a highly integrated pack concept for maximum performance is modeled.Measurements on a prototype cell are used to investigate the extent to which solid-state batteries can outperform existing technologies.Also addressed will be expected costs, which will be critical to market penetration.

Increasing demand for more powerful batteries are pushing current Li-ion technology to its limits. Recent developments are attracting high media attention and cell manufacturers are working on the realization and implementation of next battery technologies. The presentation will evaluate the market readiness and competitiveness of future technologies; e.g., high-silicon anodes, solid-state but also Na-ion in comparison to Li-ion battery technology with respect to performance, safety, scalability, and cost aspects.

An overview on BASF's latest developments for Cathode Active Materials and Recycling will be given.

Sodium-ion batteries are garnering attention; this attention is mainly motivated by the large abundance of the sodium. TIAMAT develops sodium-ion battery cells based on research work on electrochemical storage by the CNRS and the CEA. The proposed battery cells offer high power performances, long lifetime, and high safety. The chemical characteristics and the cell performances will be detailed in the presentation; it will also summarize the product development for automotive applications and the TIAMAT industrialization roadmap.

While Umicore is a global leader in cathode materials with extensive experience in battery applications, Umicore has been researching and developing its silicon anode materials for the last 12 years. Today, we are convinced our current silicon-carbon composite (Si/C) is the right answer for the next-generation EV battery system with using high-energy density cells. We are moving to the next stage to become the first European Si-anode player at scale for EV customers.

The presentation will describe the unique holistic development approach that was employed in order to exceed the goal of 300Wh/Kg and 1000 consecutive extreme fast charging cycles while maintaining the batteryâ€s health, in different form factor pouch cells, from 1Ah to 30Ah. While Si-rich anodes present a pathway to fast charging, they are prone to fast deterioration and low cycle life. StoreDot Extreme Fast Charging (XFC), high energy Si-dominant cell technology is enabled by integrating all aspects of Li ion-based cell components (anode, cathode, electrolyte, cell design, and data science).

This talk will discuss progress in performance of liquid electrolytes for use with lithium metal anodes. Rapid capacity fade and electrolyte consumption can occur with liquid electrolyte cells that contain lithium metal anodes. However, these problems can be mitigated with advanced formulations. The effect of cycling protocol can also be quite dramatic and will be reviewed in this presentation.

Sepion brings a differentiated approach to replacing graphite anodes with lithium metal by combining the latest in nanoscience, polymer chemistry, and cell engineering to safely unlock a 40% increase in electric vehicle range with a gigafactory-compatible solution.

Copper sulfide (CuS) is a naturally occurring mineral and has been used as cathode active material (CAM) in Li primary batteries in the past. The ideal discharge reaction (2 Li + CuS -> Li2S + Cu) theoretically provides 560 mAh/g(CuS) and 961 Wh/kg. Here, we discuss why CuS could be an attractive CAM for rechargeable Li-SSBs. Next to a high intrinsic mixed conductivity and ductility, CuS reacts with Li via a unique conversion reaction mechanism that leads to macroscopic phase changes during cycling. Next to cycling studies, the storage mechanism and mechanical properties are discussed using 3D tomography. 10.1002/aenm.202002394, 10.1002/aenm.202203143.

In this talk, I plan to discuss the recent development in solid-state electrolytes, especially Li-based garnets, and interface modifications that are critical for solid-state battery development.

The lithium ion conductivity of sulfide solid electrolytes is unbeaten, and their mechanical properties allow roll-to-roll procesing. Interface issues can be overcome by interlayer and coating design, and the evolution of H2S can be mitigated by chemical design. In this presentation, the current status of sulfide-based SSBs and the recent development of halide solid electrolytes will be briefly discussed, as well as the potential need for targeted design of cathode active materials for SSBs

Silicon has long been heralded as the next important anode material since it can theoretically store more than twice as much lithium as graphite anodes used in nearly all Li-ion batteries today. Ashok Lahiri, Technical Advisor & Co-Founder, will share how Enovix’s stacked cell architecture solves the four technical problems of silicon, producing a 100% active silicon anode battery designed to deliver high-energy density, as well as how Enovix is scaling-up in order to power the technologies of the future
