Abstract :
The purpose of this study is to research and develop LixV3O8 composite cathode for lithium polymer battery. We investigated electrochemical, interfacial properties and charge/discharge cycling of LixV3O8/SPE/Li cell. The radius of semicircle associated with the interfacial resistance of LixV 3O8/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 LixV3O8 was 212 mAh/g at 15th cycle. The LixV3O8/SPE/Li cell has a good properties
