Time: 1300–1400h ET
Silicon-based lithium-ion batteries exhibit severe time-based degradation resulting in poor calendar lives. This webinar reviews how calendar aging is measured, why traditional measurement approaches are time intensive, and the need for new approaches to optimize materials for next-generation silicon-based systems. Using this new approach, multiple new electrolyte systems are screened that can lead to calendar life improvements in Si-containing batteries.
An interactive Q&A session follows the presentation.
Benefits of attending the webinar
Learn about:
- What is calendar aging and how is it measured currently;
- What problems plague silicon calendar aging as compared to graphite;
- How to measure calendar aging in a faster way so that materials optimization for calendar life can be done in a faster manner;
- Some promising electrolytes for silicon-based anodes.
Presenter
Ankit Verma is a Researcher IV-Mechanical Engineering in the Center for Energy Conversion and Storage Systems at the National Renewable Energy Laboratory. His expertise is in physics-based and data-driven modeling of lithium-ion and next generation lithium metal batteries. His interests lie in unraveling the coupled reaction-transport-mechanics behavior in these electrochemical systems with experiment-driven validation to provide predictive insights for practical advancements. Predominantly, he works on improving silicon anodes energy density and calendar life as part of the Silicon Consortium Project, understanding solid-state battery limitations and upcycling of end-of-life electrodes as part of the ReCell Center.
His past works include optimization of lithium-ion battery anodes and cathodes for high-power and fast-charge applications and understanding electrodeposition stability in metal anodes. He completed a PhD in Mechanical Engineering at Purdue University.
