| Abstract: The layered trivanadate, LiV3O8, was prepared by sol-gel method with LiOH, V2O5 and H2O2 as initial reagents. The materials at different heat treatment conditions were characterized by XRD and TG-DTA. Their electrochemical behaviors were studied by galvanostatic charge-discharge and cyclic voltammetry. The results show that LiV3O8 prepared by sintering at 300 ℃ for 16 h has higher capacity, and its initial discharge capacity is 333.1 mAh·g-1, and maintains a discharge capacity of 302.8 mAh·g-1 after 10 cycles at 0.2 C and the voltage range of 1.8～4.0 V. |
