Abstract
- Current electrode materials for commercial lithium ion batteries (LIBs) suffer from poor low temperature electrochemical performance, which seriously limits their application in winter and cold climate areas. Herein, pure phase LISICON structured Li3V2(PO4)3 (r-LVP) was successfully prepared and investigated for the first time as a low temperature cathode for LIBs. Benefiting from a fast ionic conductive structure and high structural stability, the r-LVP exhibits an outstanding high rate performance in a wide temperature range from 25 °C to ā20 °C. Even at ā30 °C, a discharge capacity of 90 mA h gā1 at 0.2C can be achieved, corresponding to 80% of the room temperature capacity. After 5000 cycles at a high rate of 10C, 84% of the initial capacity can be retained at ā10 °C. Such a high rate capability and long cycle stability promise r-LVP could be a competitive candidate for low temperature LIBs.
