Abstract

Li-ion battery failures are becoming the major concern in the battery application area. A failure such as sudden capacity loss could cause catastrophic damage and loss. Li-plating, a reason causing short circuit and capacity loss, is arousing researchers' and manufacturers' interest today. Based on mechanisms of Li-plating, this paper proposed a new approach to detect the occurrence of Li-plating. With the simulation of Li-plating using COMSOL, the proposed Li-plating occurrence model is implemented under different conditions. The experimental results indicate the local effects and the onset timing of Li-plating.
