In situconstruction of polyether-based composite electrolyte with bi-phase ion conductivity and stable electrolyte/electrode interphase for solid-state lithium metal batteries

A bi-phase ionic conductive polyether-based composite electrolyte was obtained by in situ polymerization, which synergistically achieves high ion-conduction (6.6 × 10 −4 S cm −1 , 25 °C), and a chemically stable solid electrolyte interphase.
