摘要

本研究的目的是研究开发锂聚合物电池用Li/sub x/V/sub 3/O/sub 8/复合正极。研究了Li/sub x/V/sub 3/O/sub 8/ SPE/Li电池的电化学、界面性能和充放电循环。Li/sub x/V/sub 3/O/sub 8//SPE/Li电池在从100%荷电状态到90%荷电状态的放电过程中，与界面电阻相关的半圆半径增长非常缓慢。然后在放电过程中，电池电阻从10%荷电状态增加到0%荷电状态。第15次循环时，基于Li/sub x/V/sub 3/O/sub 8/的放电容量为212 mAh/g。Li/sub x/V/sub 3/O/sub 8//SPE/Li电池具有良好的性能。

Charge/discharge and interfacial properties of Li/sub x/V/sub 3/O/sub 8//Li cells with polymer electrolyte

The purpose of this study is to research and develop Li/sub x/V/sub 3/O/sub 8/ composite cathode for lithium polymer battery. We investigated electrochemical, interfacial properties and charge/discharge cycling of Li/sub x/V/sub 3/O/sub 8//SPE/Li cell. The radius of semicircle associated with the interfacial resistance of Li/sub x/V/sub 3/O/sub 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/sub x/V/sub 3/O/sub 8/ was 212 mAh/g at 15th cycle. The Li/sub x/V/sub 3/O/sub 8//SPE/Li cell has a good properties.
