Design criteria for limiting fracture in anodes for Li-ion batteries

Research output: Contribution to conferencePaper

Abstract

The limiting factor in commercializing Si anodes for Li-ion batteries lies in the severe fracture that Si experiences during electrochemical cycling. Although modeling the complete chemomechanical problem requires a multiphysics approach, our work has illustrated that fracture mechanics models can be used to obtain design criteria for developing high capacity anodes that exhibit the required mechanical and hence electrochemical stability. Based on the theoretical predictions new Sn/graphene anodes were fabricated, which upon electrochemical cycling exhibited the anticipated stable response.
