Chemomechanical modeling of lithiation-induced failure in high-volume-change electrode materials for lithium ion batteries

Abstract The rapidly increasing demand for efficient energy storage systems in the last two decades has stimulated enormous efforts to the development of high-capacity, high-power, durable lithium ion batteries. Inherent to the high-capacity electrode materials is material degradation and failure du...
