The method of producing the ion conductive film comprises the use of a primary inorganic chemical that is preferably water soluble; the preparation of a solution using a suitable solvent, preferably deionized water; and a spray deposition system. Spray deposition of a solid electrolyte matrix onto a heated substrate, preferably a substrate at 100-400 ° C. After the deposition step, lithiation or addition of lithium, followed by heat treatment, preferably heat treatment at a temperature in the range of 100 to 500 ° C., is performed to obtain a high lithium ion conductive inorganic solid electrolyte. The electrolyte can be incorporated 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 ; a group consisting of Li, Li alloy, and a metal oxide doped with Li the anode comprises a material selected from; and Li x Al z-y [Ga n B 1-n] y S w (PO 4) c, Li x Al z-y [Ga n B 1-n] y S w (BO 3 ) c , Li x Ge z-y Si y Sw (PO 4 ) c , and Li x Ge (zy) Si y Sw (BO 3 ) c (where 4 <w <20, A solid Li ion conducting electrolyte selected from the group consisting of 3 <x <10, 0 ≦ y <1, 1 ≦ z <4, 0 ≦ n ≦ 1, and 0 <c <20. |
