Li-ion batteries are complex systems, in which many competing processes slowly contribute to performance fade. The nature and magnitude of this aging are highly dependent on how the battery operates. Extreme fast charging imposes a very specific set of challenges to the cell, with broad consequences to cycle life. In this talk, we will discuss modes of aging that are particular to cells that are repeatedly exposed to high currents, focusing on detection and diagnostics. Our work supports the design of experimental solutions, and informs the development of models capable of describing the intricate phenomena that emerge at faster rates.

Takeaway

This talk will be will describe the inner working on lithium-ion battery cell and then describe the consequences of fast charging on the performance and aging of battery materials. Material design to enable fast-charging will also be discussed.

Intended Audience

This talk will be suitable for a general audience.
