| Abstract: | LiAlxV1-xPO4F（x=0.0.02.0.04.0.06.0.08）cathode materials for Li-ion battery were synthesized by carbothermal reduction method. The structures and electrochemical properties of materials were tudied by XRD .EIS. galvanostatic charge-discharge and cyclic voltammetry method. The results showed that LiAl0..04V0.96PO4F sample had the best electrochemical performance among these materials, its initial specific discharge capacity was 102.01 mAh/g at 0.2 C, the capacity retention rate was 85.85% after 30 cycles. |
