This session introduces an innovative approach for testing battery cell lifetimes in automotive applications by devising scenarios that reflect diverse customer behaviors through fleet data analysis. This method captures realistic battery degradation trends under actual driving conditions and bridging the gap between lab-scale cell testing and vehicle-level aging tests. It also addresses the warranty concerns while complementing traditional lab testing environments.

The Dalhousie group demonstrated that expansion of active materials causes electrolyte flow in cylindrical cells upon cell cycling. We discuss the influence of this electrolyte inhomogeneity on cell performance and lifetime. This novel mechanism—which we termed "electrolyte motion-induced salt inhomogeneity” (EMSI)—is not restricted to cylindrical cells but can occur in all large-format lithium-ion cells under high compression.

A lower weight EV battery will improve overall vehicle efficiency and energy use when the vehicle is in operation. There are many paths to reducing battery weight, through new materials and technologies, but also through prudent synergistic design and use cases. These routes can introduce other significant drawbacks as well, which need to be addressed in both the battery and vehicle design processes. This talk will compare and contrast different drivers and their respective figures of merit on battery lightweighting.

The United States Advanced Battery Consortium is a collaborative research partnership between Ford, General Motors, and Stellantis. USABC has been pursuing advanced energy storage technologies for electrified vehicles for over 30 years. In January 2024, DOE announced that the consortium will receive $60 million to support domestic battery development. (Pending ongoing negotiations.) This talk will highlight the recent history of USABC, as well as provide an overview of expected upcoming funding opportunities for US-based battery suppliers.

Solid state batteries garner a large amount of attention as the future of next-generation battery chemistries and as a result it can be difficult to separate hype from reality in this important technology. This talk will discuss the status of solid state battery commercialization, important challenges remaining, and technology needs from an automotive OEM perspective.

Battery degradation is to a large part attributed to the anode. As the industry strives for higher performance batteries, the cathode is moving more into focus. If the battery can be utilized better, cost is effectively reduced and energy density increased. We have studied several aspects of cathode degradation and want to review it from an automotive perspective.

The Vehicle Technologies Office (US DoE) has established a consortium of six national laboratories to address the challenges of enabling sustainable cathode technologies. This consortium is focusing efforts across a wide range of materials and technology readiness levels. In this presentation, we will discuss ongoing efforts within the program aimed at the design, synthesis, and characterization of Mn-rich cathodes as alternative, next-generation materials.

With the growing adoption of batteries, the effective management of battery systems has become increasingly critical. The advent of Wireless Battery Management Systems (wBMS) represents a significant innovation in battery management to overcome the challenges of traditional wired BMS, including complexity, increased weight, maintenance difficulties, and failure.  wBMS offers a robust solution, eliminating physical connections. It offers enhanced flexibility, reduced packaging complexity, and improved reliability. This talk explores its evolution, current state, and future directions. It will provide a comprehensive overview of state-of-the-art wBMS technologies, compare wireless communication technologies. discuss their performance in terms of efficiency, reliability, scalability, and security.

This presentation shows a systematic evaluation of NMC and LMP blends with the aim of mapping the blend/performance space. The focus will be on performance metrics for high-energy cells with power performance sufficient for auto applications.

In the rapidly evolving landscape of electric vehicles, ensuring battery safety and performance is paramount. The presentation delves into the innovative application of AI-powered digital twins for battery system.This cutting-edge approach aims to enhance battery safety, reduce warranty claims, and optimize performance through precise failure prediction and health monitoring. By leveraging data from development, telematics, and in-vehicle usage, this scalable digital twin architecture promises to revolutionize the automotive industry, offering significant cost savings and improved battery life

This presentation will cover the EV Sales Review of 2024, expectations going forward, and implications on battery demand, and will share the latest insights from collecting the facts in the EV industry. You will understand the best sellers, which countries and regions are doing the most for EV adoption, and what to expect in the future, both short term, and long term. These forecasts will also be translated into the battery demand.

The battery market saw a deployment of around 1.2TWh in 2024. Battery evolution is occurring in many different directions, with each avenue viewed as ‘the next big thing.’ Developments include advancements in LFP chemistry with LMFP, the use of silicon anodes, sodium ion or the emergence of ultra-fast charging technologies. However, solid-state batteries have gained interest for over a decade now.

There have been many announcements for capacity, new technology, and impact to the markets—many of these are overstated. Avicenne Energy will be sharing a realistic view and presenting updates on the mass commercialization of lithium-ion battery. Many emerging technologies could have impact for the automotive markets. Technologies to be covered are lithium-ion, dry process, solid state and sodium ion with key drivers, progress to date and forecasts.
