NOVEL LITHIUM-AIR BATTERY BASED ON HIGH-DENSITY SOLID ELECTROLYTE

摘要

Disclosed is a novel lithium-air batterybased on a high-density solid electrolyte. The lithium-air battery comprises: a negative electrode, a porous oxygen electrode, and a solid electrolyte layer sandwiched between the negative electrode and the porous oxygen electrode. The negative electrode material comprises lithium, a lithium alloy and/or a lithium-metal-containing composite. A porous conductive carrier, a catalyst, ion conductor material, lithium salts and/or an adhesive are uniformly mixed and dried to obtain the porous oxygen electrode. The solid electrolyte layer material comprises a lithium lanthanum zirconium oxide-based ceramic, a lithium lanthanum titanium oxide-based ceramic, a lithium aluminum titanium phosphate-based ceramic and/or a lithium silicophosphate-based ceramic.
