The method for producing an ion conductive film comprises the use of a primary inorganic chemical which is preferably water soluble and combining the solution with a suitable solvent, preferably deionized water; And spray depositing the solid electrolyte matrix onto the substrate, preferably heated to 100-400 ° C., using a spray deposition system. After the deposition step, lithiation or lithium addition is carried out, and then thermal processing is preferably performed at a temperature of 100 to 500 ° C. to obtain a high lithium ion conductive inorganic solid electrolyte. The electrolyte is introduced into a lithium ion battery. The Li-ion battery includes a cathode comprising a material selected from the group consisting of LiMn 2 O 4 , LiMnNiCoAlO 2 , LiCoO 2 , LiNiCoO 2 , and LiFePO 4 ; An anode comprising a material selected from the group consisting of Li, a Li alloy, and a metal oxide doped with Li; And Li x Al zy [Ga n B 1-n ] y S w (PO 4 ) c , Li x Al zy [Ga n B 1-n ] y S w (BO 3 ) c , Li x Ge z - y Si y S w (PO 4 ) c , and Li x Ge (zy) Si y S w (BO 3 ) c , wherein 4 <w <20, 3 <x <10, 0 ≦ y <1 A solid Li-ion conductive electrolyte, wherein 1 ≦ z <4, 0 ≦ n ≦ 1, and 0 <c <20. |
