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 <i>via</i> 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<sup>-1</sup> and average coulombic efficiency of 99.55%.
