Notes:
A general continuum model has recently been proposed for the dynamics of ionintercalation in a single crystal of rechargeable-battery electrode materials [1]. When applied tostrongly phase-separating, highly anisotropic materials such as LiFePO4, phase-transformationwaves are predicted between the lithiated and unlithiated portions of a crystal. In this paper, weextend the analysis of the wave dynamics, and we describe a new mechanism for current capacityfade through the interactions of these waves with defects in the material
