In-situ polymerizable, elastic, rigid, and fatigue-resistant composite solid electrolyte for all-solid-state lithium metal batteries

Abstract

A polymerizable polymer composition, an entangled polymer including the polymerized composition, a composite solid electrolyte including the entangled polymer, an all-solid-state lithium metal battery including the composite solid electrolyte, and a method of preparing the polymerizable polymer composition are provided. The polymer composition includes first and second monomers, an unsaturated hydrocarbon, nanoparticles, a metal salt, and a stabilizer. The first and second monomers have first and second moieties, respectively, the unsaturated hydrocarbon has a third moiety, the surface of the nanoparticles has a coating having fourth moieties. The entangled polymer further includes ion transport pathways and chemical bonds between any of the first, second, third, and fourth moieties.
