LiV3O8 NANOMATERIAL AS ANODE WITH GOOD CYCLING PERFORMANCE FOR AQUEOUS RECHARGEABLE LITHIUM BATTERIES

LiV3O8 nanorod material was prepared by a simple sol-gel method. The electrochemical properties of the as-prepared LiV3O8 in 0.5 M Li2SO4 aqueous electrolyte were studied through cyclic voltammograms (CV) and discharge-charge measurements. Experiments show that this nanorod material can deliver the capacities of 72, 62 and 53 mAh/g at 20, 50, 100 mA/g, respectively. After 50 cycles, it can maintain 64, 47 and 40 mAh/g, corresponding to 88%, 76% and 77% of the initial capacities, which suggest that this nanorode material presents good cycling performance as anode material for aqueous rechargeable lithium batteries.
