In-situ plasticized polymer electrolyte with double-network for flexible solid-state lithium-metal batteries

An in-situ plasticized solid-state polymer electrolyte with double-network (DN-SPE) is constructed to develop flexible solid lithium metal battery (SLB). In-situ plasticization of the double network in DN-SPE drastically enhances the ion conductivity and maintains high thermal stability (stable up to 200 °C). SLB constructed by coupling DN-SPE with Li-metal and LiFePO4 demonstrates impressive electrochemical and flexible properties.218
