LATP修饰LCO在高压贫液锂电池中的性能研究
Research on LATP-modified LCO in high-voltage Li-metal cells with lean electrolyte
摘要
Abstract
Achieving high energy density exceeding 500 Wh/kg in lithium metal batteries can be real-ized by increasing the charging voltage,positive electrode loading,and reducing the electrolyte amount. Modification of LiCoO2 with Li1.3Al0.3Ti1.7(PO4)3 improves the stability of lithium metal batter-ies in high voltage and low electrolyte environments. LATP@LCO prepared by planetary dispersion method exhibits the best comprehensive performance,with an initial discharge specific capacity of 212.0 mAh/g at 0.1 C,a coulombic efficiency of 95.3％,and a capacity retention of 87.8％ after 85 cycles,showing a significant improvement compared to the pure LCO with a capacity retention of 57.8％. This is of great significance for enhancing the cycling lifespan of ultra-high energy density lithium batteries.关键词
