Abstract

The purpose of this study is to research and develop $Li_xV_3O_8$ composite cathode for lithium polymer battery. We investigated electrochemical, interfacial properties and charge/discharge cycling of $Li_xV_3O_8$/SPE/Li cell. The radius of semicircle associated with the interfacial resistance of $Li_xV_3O_8$/SPE/Li cell increased very slowly during discharge process from 100% SOC to 90% SOC. And then the cell resistance was increased at discharge process from 10% SOC to 0% SOC. The discharge capacity based on $Li_xV_3O_8$ was 212mAh/g at 15th cycle. The $Li_xV_3O_8$/SPE/Li cell has a good properties.
