Chemical origins of a fast-charge performance in disordered carbon anodes

Abstract:

Fast charging of lithium-ion cells often causes capacity loss and limited cycle life, hindering their use in high-power applications. Our study employs electrochemical analysis and a multiphysics model to identify and quantify chemical and physical constraints during fast charging, comparing state-of-the-art graphite and nanocluster carbon (nC, a disordered carbon) anodes. The combination of modeling material phase separation phenomena with ion-electron transfer theory reveals significant ins...
