LITHIUM METAL SOLID-STATE BATTERIES AND THE FABRICATION METHOD THEREOF

A lithium metal solid-state battery includes a lithium metal anode and a cathode that includes an active material, a conductive material, a binder, and a current collector is provided. The active material has one or more lithium-based compounds selected from lithium cobalt oxide, lithium nickel manganese cobalt oxide, lithium iron phosphate, lithium manganese oxide, lithium sulfur, and lithium nickel cobalt aluminum oxide. The battery also includes at least one porous polymer separator with a porosity ranging from approximately 30% to 90%. The solid-state electrolyte includes an organogel, which contains covalent organic frameworks (COFs) fabricated through the condensation of monomers with a specified formula.
