Abstract

Improvement in the rate properties of orthorhombic LiVOPO₄ was investigated and it was found that making a fine powder of LiVOPO₄ by the mechanical milling pretreatment is effective for increasing the de-intercalation capacity of Li from LiVOPO₄. The electrochemical de-intercalation capacity at high current density can further increase by optimizing the acetylene black amount as a conducting binder. The optimized acetylene black amount was 15 wt.% and intercalation capacity of Li was achieved a value of 100 and 60 mAh g^-1 at high rate condition of C/5 (0.4 mA cm^-2) and 1C (2 mA cm^-2), respectively.
