Abstract:

Li-ion batteries is one of promising energy storage systems for power tools and electric vehicles due to their high specific capacity and energy density. However, it is observed that repeated cycling leads battery material fracture, degradation and aging, and it could eventually result in irreversible capacity retention. Mechanical, thermal, and electrochemical coupled models were developed at different length-scales to better identify determining factors affecting Li-ion battery performance under a wide range of current rates (C-rates). The developed numerical and computational models can be used in various battery chemistries for better design energy storage systems with higher C-rates and longer cycle life.
