Abstract: Li3V2(PO4)3/C was synthesized by sol-gel method with citric acid as chelate and C sources.Physical and electrochemical performances of as-prepared materials were characterized through XRD,SEM and galvanostatic charge-discharge tests,etc.The results showed that products produced by calcining at 800 ℃ for 12 h had a single phase crystal structure and relatively small particle sizes with uniform distribution.At 0.1 C,0.5 C and 1 C,the initial specific discharge capacities were 153.0,143.1 and 130.6 mAh·g-1,respectively,and capacity efficiencies were 93.1%,85.4% and 77.3% after 50 cycles,respectively.Charge efficiencies were all above 80% and discharge voltages were higher.

Key words: Li-ion batteries, cathode material, Li3V2(PO4)3, sol-gel
