A method for making ion conducting films includes the use of primary inorganic chemicals, which are preferably water soluble; formulating the solution with appropriate solvent, preferably deionized water; and spray depositing the solid electrolyte matrix on a heated substrate, preferably at 100 to 400°C using a spray deposition system. The deposition step is then followed by lithiation or addition of lithium, then thermal processing, at temperatures preferably ranging between 100 and 500 °C, to obtain a high lithium ion conducting inorganic solid state electrolyte. The electrolyte is incorporated into a lithium ion battery. The Li ion battery comprises: a cathode comprising a material selected from the group consisting of : LiMn204, LiMnNiCoA/02, LiCo02, LiNiCo02, and LiFeP04; an anode comprising a material selected from the group consisting of :Li, Li alloys, and metal oxide doped with Li; and, a solid Li -ion conducting electrolyte selected from the group consisting of: LixAlz. y [GanBl - n] ySw (P04) c, LixAlz -y [GanBl -n] ySw (B03) c, LixGez -ySiySw (P04) c, and LixGe(z- y) SiySw (B03 ) c, where 4 < w < 20.3 < x < 10,0 <= y < 1.1 <= z < 4,0 <= n <= 1, and 0 < c < 20 |
