Failure Analysis of Next Generation Si Based Anodes
Silicon (Si) is an attractive alternative to graphite due to its high theoretical capacity of 3500 mAh-g-1 and its high abundance on earth. Unfortunately, Si is plagued by significant volume expansion during charge/discharge, upwards of 300%. As a result, researchers and companies have focused their attention on mitigating the disadvantages of Si. With various methods the aim is to create a Si based anode that has a stability comparable or better then graphite. With increasing interest, it is important to discuss and determine abuse testing and failure analysis techniques that can effectively determine the durability of these new anodes.
This webinar will focus on the following key topics:
• Why is it important to look at alternative anodes to graphite?
• The advantages and disadvantages of Si based anodes
• Creation of new anodes to alleviate the disadvantages of Si
• Customized abuse testing and failure analysis of Si based anode cellsPresenter

Intellectual Property Clash of Copper Current Collectors
High voltage cathode materials, dendrite-preventing electrolytes, and new anode architectures often grab headlines. But what may send shockwaves through the battery industry is the winner of the patent and trade secret battle being waged by SK Nexilis Co., Ltd. and Solus Advanced Materials Co., Ltd. The spoils of war being the right to make and sell copper foils used for current collectors in electric vehicle batteries. With parallel litigation occurring in the United States, South Korea, and Europe, and patent invalidation proceedings before the US Patent Office, this case is one to watch for battery manufacturers worldwide. This talk will highlight the procedural posture and the intellectual property tools being brought to bear by both sides in this on-going dispute.
This webinar will focus on the following key topics:
• Building patent thickets around single battery components
• Trade secret rights complementary to battery manufacturing patent rights
• Strategically acquiring foreign patent rights with high investment returns
• Value of patents given the increased institutional denial of proceedings to invalidate patentsPresenter

A New Generation of Aging Models for Lithium-ion Batteries
Over the past years, scientists have invested a lot of time and resources to optimize semi-empirical, physico-chemical, and data-driven simulation models. All of them show different challenges and limitations. To overcome this dead end, scientists and engineers combine physicochemical-mechanical degradation effects and integrate them into (semi)-empirical as well as data-driven approaches. We call this combination physics-motivated semi-empirical aging models.
This webinar will focus on the following key topics:
• How capacity aging model is optimized using bootstrap resampling
• The new generation of physics-motivated semi-empirical aging models: OCV aging, degradation modes, understanding the accuracy of models, simulation of swelling force
• The new TWAICE simulation model portfolio: base model, customized base model, premium model
• Vision and outlookPresenters

Latest Advancements in Calorimetry for Battery Performance and Safety
This presentation covers two essential calorimetric techniques for performance and safety testing of high-energy batteries. Starting with THT’s latest innovation, the IBCx, an isothermal battery calorimeter that delivers precise thermal control, providing crucial insights into the effects of C-rates on heat output, efficiency, and temperature during charge and discharge cycles. The IBCx also allows for quick measurement of heat capacity within the same system.
As the battery market shifts toward larger, higher-capacity cells in the form of long, thin blade cells, THT has developed its largest adiabatic ARC. The ARC is designed to evaluate the thermal stability and safety limits of these batteries under extreme conditions such as elevated temperatures, overcharge, short circuit and nail penetration. The presentation also highlights complementary test methods including online gas analysis.
This webinar will focus on the following key topics:
• Principles of isothermal and adiabatic calorimetry testing for high-energy batteries
• Advantages and limitations of these two methods
• New product developments from THT to address market demand for testing of large format, high-capacity cells
• Integration of on-line gas analysis with ARC testingPresenter
