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.

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.

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.

9:30 am Benchmarking Battery Development against the Commercial Battery Market

Christianna Lininger, PhD, Director of Battery Science and Engineering, Voltaiq

Benchmarking new technologies against the landscape of commercially available technologies is key to stay competitive. This talk presents a solution to the difficulty of benchmarking new technologies: The Battery Index. We share the methodologies so audience members can test their own cells and compare against the commercial database. Next we present the comparative performance for cells available today and share ‘best practices’ with regard to battery testing, engineering, analysis, and development.

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.

11:15 am

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.

11:45 am High-Energy Li-ion Batteries: Silicon-Dominant Anodes and NMC Cathodes with an NMP/PVDF-Free Process

Ben Cao, PhD, Vice President of R&D, Nanoramic Laboratories

Neocarbonix®at the Core is a battery technology that enables Tier-I battery manufacturers and automotive OEMs to achieve next-gen battery performance while using existing equipment and manufacturing processes. By combining a silicon dominant anode and high capacity loading cathode, the technology increases cell level energy density by 35% reaching over 330 Wh/kg and 850 Wh/L in current R&D prototypes.
