摘要：
The cathode material Li3V2 (PO4)(3) is synthesized for Lithium Ion batteries based on wet ball-milling then high temperature carbon-thermal sintering. We had characterized them with the measurements of XRD ray diffraction, elemental analysis and electrochemical property tests. The results show that we synthesized sample is monoclinic structure; We first synthesized the Li3V2 (PO4)(3) through the using conductive carbon, the extra conductive carbon can increase the conductivity of the material. The initial charge capacity is 126.16 mAh/g and initial efficiency is 97.84 % at room temperature, charging voltage3.0 similar to 4.3 V,0.1 C rate charging, respectively and the surface of the material is smooth, it's grains grow better, there are excess conductive carbon even attached to the material to improve the conductivity of the material.
