Inorganic solid electrolyte glass phase composite and a battery containing an inorganic solid electrolyte glass phase composite

摘要

An inorganic solid electrolyte glass phase composite is provided comprising a substance of the general formula La_2/3-xLi_3xTiO₃ wherein x ranges from about 0.04 to about 0.17, and a glass material. The glass material is one or more compounds selected from Li₂O, Li₂S, Li₂SO₄, Li₃PO₄, P₂O₅, P₂O₃, Al₂O₃, SiO₂, CaO, MgO, BaO, TiO₂, GeO₂, SiS₂, Sb₂O₃, SnS, TaS₂, P₂S₅, B₂S₃, and a combination of two or more thereof. A lithium-ion conducting solid electrolyte composite is disclosed comprising a lithium-ion conductive substance of the general formula La_2/3-xLi_3xTiO₃—Z wherein x ranges form about 0.04 to 0.17, and wherein “Z” is the glass material identified above. A battery is disclosed having at least one cathode and anode and an inorganic solid electrolyte glass phase composite as described above disposed on or between at least one of the cathode and the anode.
