A novel three-dimensional (3D) finite element based model simulating Li diffusion and intercalation-induced stress in LiCoO2 reconstructed by using focused ion beam/scanning electron microscopy (FIB/SEM) tomography is presented. The resolution of reconstructed LiCoO2 cathode structure is higher than that of typical X-ray computed tomography (CT), thus allowing to analyze detailed Li distribution and intercalation-induced stress. In this work, the local and macroscopic electrochemical and mechanical response of the cathode material as a function of galvanostatic cycling is studied. Using the model, the effects of the discharge-rate on deleterious effects, such as intercalation-induced stress, are assessed.
