Highly stable LiV3O8 with a nanosheet-structure was successfully prepared using polyethylene glycol (PEG) polymer in the precursor solution as the structure modifying agent, followed by calcination in air at 400oC, 450oC, 500oC, and 550oC. These materials provide the best electrochemical performance ever reported for LiV3O8 crystalline electrodes, with a specific discharge capacity of 260 mAh g-1 and no capacity fading over 100 cycles at 100 mA g-1. The excellent cyclic stability and high specific discharge capacity of the material are attributed to the novel nanosheets structure formed in LiV3O8. These LiV3O8 nanosheets are good candidates for cathode materials for high-energy lithium battery applications.
