Chemomechanics of Battery Materials

The performance of emerging chemistries for LIBs in electric and hybrid vehicle applications is greatly limited by failure during porous, polycrystalline LCO particle long term battery cycling. As a part of this project, we are developing theoretical and numerical methodologies to understand the underlying chemomechanical mechanisms that control lithium intercalation and degradation. Of great interest is to develop strategies to prevent/minimize chemomechanical degradation by tuning microstructural parameters such as particle morphology, grain size, and crystallographic texture.
