| Abstract: | Li3V2（PO4）3 was prepared by sol-gel method with lithium hydroxide,ammonium vanadate and ammonium dihydrogen phosphate as raw materials, effects of different calcination temperature and calcination time on the morphology and structure of materials were studied by SEM and XRD. The results show that the optimal conditions are as follows： the calcination temperature 800 ℃, the calcination time 9 h; the first charge and discharge capacities of prepared Li3V2（PO4）3 can reach to 129.1 and 127.2 mAh/g at 0.1 C, and they can still maintain 124.7 mAh/g after 40 cycles. |
