Abstract
The degradation modes of MCMB/LiCoO2 Li-ion battery were investigated.The results showed that the state of charge (SOC) offset of cathode,structure degradation of cathode,polarization of cathode and anode and kinetics decay of electrolyte were the common cause of the full battery capacity loss.The cathode SOC offset was the most important reason for the full battery capacity loss at any number of cycles.The identifying state modes were established by degradation mode,and the charge-discharge curve of the battery was simulated,it was found that the simulation results were coincided with the experimental results.The state change of the battery in cyclic aging process was analyzed based on the diagnosis method of degradation mode.关键词
