The aging characteristics of lithium titanate batteries under ultra-high discharge rate were studied in this paper. The discharge characteristics is highly temperature-dependent under 55C discharge rate. The capacity retention rate is about 73% after 100 cycles of 55C discharge. The in-situ analysis incremental capacity analysis (ICA) was used to analyze the aging mechanism, and it was found that the main reason for the capacity fading was the loss of active material of the positive electrode, which leads to an increase of polarization resistance under 55C discharge rate.
