Abstract

A facile interfacial engineering method via in situ electro-deposition was developed to stabilize the PEO-based solid electrolyte in high voltage solid-state lithium metal batteries (Li/PEO-LiTFSI/LiNi0.5Co0.2Mn0.3O2), which demonstrate a superior capacity retention of 72.3% after 200 cycles in 3.0-4.2 V. The critical factors for the interfacial engineering method were also demonstrated in this study.
