If a Lithium-ion Cell Can Operate for More Than 6 Months at 85°C How Long Can It Last at Ambient Temperature?
Jeff Dahn, FRSC, PhD, Professor of Physics and Atmospheric Science, NSERC/Tesla Canada Industrial Research Chair, Canada Research Chair, Dalhousie University
In a few of our recent papers, we have presented Li-ion cell designs with liquid electrolytes that give astounding lifetime at temperatures as high as 85°C. In fact, we have been testing these cells now at 100°C and they are operating well for more than one month so far. I will discuss what is required to make such awesome cells and then consider what their lifetime at ambient temperature might be. I will show that the energy density of these cells is very reasonable and that Co-free moderate-nickel designs also work equally well.
Next-Generation Batteries - An Update on Li Metal Battery and All Solid-State Battery
Shirley Meng, PhD, Professor, University of Chicago; Chief Scientist, Argonne Collaborative Center for Energy Storage Science, Argonne National Laboratory
With the recent success in deploying lithium-ion batteries for light-duty passenger cars, it is time for researchers and scientists to work on a road map of next-generation batteries beyond lithium-ion. In this talk, I will give an update on the current status of research efforts in enabling lithium metal batteries and all solid-state batteries. A few cutting-edge scientific tools will be introduced, including X-ray CT, Cryo-EM, Titration GC, and more, all aimed at quantitative understanding of the failure mechanisms of next-gen batteries.

FAST CHARGING

Craig Wohlers, Executive Director, Conferences, Cambridge EnerTech
Ultra-Fast Charging LIBs while Ensuring Safety and Lifespan
Rachid Yazami, PhD, Founding Director, KVI PTE, Ltd. Singapore; Visiting Scholar, California Institute of Technology
Departing from an over one-century-old constant current (CC) based charging methods we have developed a non-CC ultra-fast charging protocol based on voltage control and current and temperature monitoring. The new protocol uses non-linear voltammetry (NLV) in which a stepwise series of voltage plateaus is applied with short rest times within each plateau. NLV parameters are set according to the LIB cell chemistry, the initial and the final (target) state of charge and the state of health. It is found that NLV enables fully charging specific cells in as short a time as 6 minutes without overheating or compromising the lifespan.

EV BATTERY MARKET EXPANSION
EV用電池市場の拡大

Kevin Wu, Scientific Principal, Thermal Management Technologies, Henkel
Optimum thermal management is key to battery safety. Current solutions use liquid gap fillers and gap pads as a thermal interface. Next-generation batteries will become part of the structural integrity of an electric car due to new designs. This will require TIM selection to bundle thermal performance with high bonding strength. Thermally Conductive Adhesives offer an effective solution. This presentation will consider factors in selecting the best material.
Energy Storage Supply Chain: Challenges and Opportunities
Venkat Srinivasan, PhD, Director, Center for Collaborative Energy Storage Science, Argonne National Laboratory
As the world embarks on widespread decarbonization, the supply chain crunch for batteries has become front and center around the world. In the United States, the issues are widespread, from material availability to the lack of cell and pack manufacturing. Recycling, which could bridge the supply gap, is still in its early stages. With the expected growth in the storage market, tactical approaches to solve the challenges will not suffice. What is needed is a comprehensive strategy that brings a holistic approach to solve the battery supply chain issues. An important part of the strategy is a newly established public-private partnership, Li-Bridge, created by Argonne National Lab on behalf of the Department of Energy, and partnered with NAATBatt International, New York Battery and Energy Storage Technology Consortium (NY-BEST), and New Energy Nexus. Li-Bridge has been bringing together US industry and federal government representatives to brainstorm the challenges and the opportunities. This talk will summarize the strategy for decarbonizing the economy and the opportunities this presents for diversifying the supply chain. The talk will also summarize the recommendations coming out of the recently published Li-Bridge report.

Cation Mixing and Capacity Loss in Li||Ni0.6Mn0.2Co0.2O2 Cells: Experimental Investigation and Application of the Multi-Site, Multi-Reaction Model
Mark W. Verbrugge, PhD, Director, R&D Chemical & Materials Systems Lab, General Motors Company
We clarify degradation phenomena in a pouch cell that contains an NMC622 insertion electrode and a Li counter electrode. Greater than 500 cycles have been achieved in these cells employing 4 mAh/cm2 for both the initial Li metal negative and the NMC622 positive, and we find that cation mixing within the NMC622 is prevalent. The MSMR model along with a new degradation model enable quantitative treatment of experimental data.

Christianna Lininger, PhD, Director of Battery Science and Engineering, Battery Engineering & Sciences, Voltaiq Inc
Benchmarking new technologies against the landscape of what iscommercially available is key to stay competitive. This talk presents solutions to that difficulty through use of "The Battery Index". We share the methodologies audience members can use to test their own cells and compare against a commercial database. We then present the comparative performance for cells available today and share ‘best practices’ with regard to battery testing, engineering, analysis, and development.
Coffee Break in the Exhibit Hall with Poster Viewing10:00 am
Battery Design and Process Considerations for Sustainability
Oliver Gross, MASc, SME Energy Storage and Conversion, Advanced Propulsion Technology, Stellantis
The anticipated large expansion in the application of traction batteries will increase the demand and use of several critical materials, such as lithium, nickel, cobalt, and copper. There are several parallel approaches being considered to manage the consequences that such a great increase in material demand brings. This talk will discuss cell chemistry and pack design selection as well as considerations for battery service, remanufacturing, repurposing, and recycling.
Polarization and Heat: Reducing Heat Generation in Cells by Optimizing the Recuperation Strategy
Frederik Morgenstern, Senior Battery Technology Engineer, BMW Group
Recuperation during breaking is one of the key contributors of highly efficient EVs. While energy can be recuperated during breaking, this process inadvertently generates heat in the system, which can cause the battery to degrade faster.Here we highlight how recuperation pulses can instead result in a reduction of heat generation in cells by depolarizing them, leading to overall lower cell temperatures when compared to systems without recuperation.

Ben Cao, PhD, Vice President of R&D, Nanoramic Laboratories
Li-ion battery regulations regarding CO2 emissions and recycled content are on the rise. Stay ahead of these policies with Neocarbonix at the Core electrode technology, which can reduce CO2 emissions during manufacturing by 25% and simplify battery recycling. This is possible by replacing toxic NMP solvent and PVDF binder with a 3D carbon matrix. Batteries made with Neocarbonix also have 35% higher energy density and 27% lower costs.
