N2 - Synthesis and the electrochemical Li de-intercalation properties of LiVOPO4 as the alternative cathode material for Li ion rechargeable battery were investigated. Two types of LiVOPO4 structures, orthorhombic and triclinic phases can be prepared by changing calcination temperature. At current density of 0.04 mAcm-1 (C/50), orthorhombic phase shows the discharge capacity of 90 mAhg-1 with flat potential of 3.7 V vs. Li/Li+, however, almost no Li deintercalation capacity was observed on triclinic phase. Orthorhombic phase is also exhibited a good cycle stability for Li de-intercalation and intercalation.
