Charge/discharge and interfacial properties of LixV3O8/Li cells with polymer electrolyte

The purpose of this study is to research and develop Li_xV₃O₈ composite cathode for lithium polymer battery. We investigated electrochemical, interfacial properties and charge/discharge cycling of Li_xV₃O₈/SPE/Li cell. The radius of semicircle associated with the interfacial resistance of Li_xV 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 Li_xV₃O₈ was 212 mAh/g at 15th cycle. The Li_xV₃O₈/SPE/Li cell has a good properties
