文摘
- •
Electrolytes including 0.8, 1.0, 1.2 and 1.4 m LiBF4 were prepared in EC:DMC solvents.
- •
After electrochemical tests, the cells containing LiBF4 electrolytes were disassembled.
- •
The effect of electrolytes on the stability of LiMn2O4 cathode materials were studied.
- •
The LiBF4 concentration should be optimized to keep stable of spinel LiMn2O4 cathode.
- •
1.2 m electrolyte yielded maximum discharge capacity, provided better cathode stability.
