摘要：

We performed the degradation and life prediction of lithium-ion batteries using an electrochemical-based degradation model. Numerical simulation was carried out considering three different degradation models (that is, SEI growth, SEI growth on the particle crack, and Li plating), and the DFN model was employed to solve the electrochemical kinetics and complex mass transfer phenomena. The result predicted an 80% of capacity decrease on reaching 9.16 years, in which the contribution of the SEI growth on the particle crack was dominant. The effect of the SEI growth was small, and the influence of Li plating became significant with decreasing temperature and increasing C-rate.
