LiFePO4在季铵盐离子液体电解液中的电化学性能

摘要

The electrochemical behavior of olivine LiFePO4 electrode in electrolytes based on ammonium ionic liquids was investigated by using cycling voltammetry, galvanostatic charge-discharge techniques.The results show that electrode scan rate and temperature influences specific capacity and cycling performances of the olivine LiFePO, electrode.%应用循环伏安和恒电流充放电等方法研究了橄榄石型LiFePO4正极材料在季铵盐离子液体电解液中的电化学嵌脱锂性质。研究表明：电极的扫描速率和工作温度均可影响LiFePO4正极材料的充放电容量和循环性能。
