摘要
具有富锂锰氧化物(LRMO)阴极的固态锂金属电池在界面兼容性方面面临挑战。本研究通过双组分调制改善了聚氯乙烯凝胶电解质与电极之间的界面。优化后的电解质具有较高的氧化稳定性,有利于形成富无机界面相,有利于界面的长期稳定性。因此,4.6 V Li|LRMO电池在0.2℃下稳定工作100次,初始容量为215.2 mAh/g,平均库仑效率为99.55%。
Dual-component modulation strategy for enhancing interfacial compatibility in 4.6 V LRMO-based solid-state lithium metal batteries†
Solid-state lithium metal batteries with a Li-rich manganese oxide (LRMO) cathode suffer from challenges in interfacial compatibility. This study improves the interface between a PVC-based gel electrolyte and electrodes via dual-component modulation. The optimized electrolyte exhibits high oxidation stability and facilitates the formation of inorganic-rich interphases, contributing to the long-term stability of the interface. Therefore, the 4.6 V Li|LRMO cells operate stably for 100 cycles at 0.2C, delivering an initial capacity of 215.2 mA h g−1 and average coulombic efficiency of 99.55%.
