TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: Organometallic compound in coating liquid for positive electrode active material layer forming is organic lithium compound of manganese, cobalt, nickel, and/or iron. Metal oxides are lithium complex oxides containing manganese, cobalt, nickel, and/or iron. Lithium complex oxide is LiMO2, LiMPO4, Li2MSiO4, and/or lithium manganese oxide (LiMn2O4). Organometallic compounds contained in coating liquid for solid electrolyte layer forming are organophosphorus compound and organic lithium compound. Metal oxide of inorganic thin film is lithium complex oxide containing phosphorus e.g. lithium phosphorus oxide (Li3PO4), lithium oxide-aluminum oxide-titanium oxide-phosphorus oxide (Li2O-Al2O3-TiO2-P2O5), lithium oxide-aluminum oxide-germanium oxide-phosphorus oxide (Li2 O-Al2O3-GeO2-P2O5), lithium oxide-lanthanum oxide-titanium oxide (Li2O-La2O3-TiO2), and/or lithium oxide-lanthanum oxide-zirconium oxide (Li2O-La2O3-ZrO2) or lithium complex oxide containing lanthanum e.g. lithium oxide-lanthanum oxide-titanium oxide (Li2O-La2O3-TiO2) and/or lithium oxide-lanthanum oxide-zirconium oxide (Li2O-La2O3-ZrO2). Organometallic compounds contained in coating liquid for solid electrolyte layer forming are organic lanthanum compound and organic lithium compound. Organometallic compound contained in coating liquid for negative electrode active material layer forming is organometallic compound of titanium, lithium, niobium, indium, tin, and/or zinc. Metal oxide is lithium-titanium oxide (Li4Ti5O12), niobium oxide, indium oxide, tin oxide, zinc oxide, and/or titanium oxide. Substrate is glass substrate, ceramic substrate, or heat-resistant plastic film. Board or foil which contains single metal or alloy is used as positive electrode collector layer or negative electrode collector layer. Organic lithium compound is lithium-2,4-pentanedionate (Li(C5H7O2)), lithium ethoxide (Li(C2H5O)) and/or lithium-tert.-butoxide (Li(C4H9O)).M=Mn, Co, Ni, or Fe.Preferred Processes: Energy beam irradiation is irradiation of UV ray from low pressure mercury vapor lamp, amalgam lamp, or excimer lamp at less than or equal to 200 nm. Packing density of inorganic thin film which has metal oxide is controlled by controlling dew point temperature of oxygen-containing atmosphere e.g. air. Organometallic compound, organic lithium compound, organophosphorus compound, and/or organic lanthanum are dissolved in organic solvent to prepare coating liquid.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: Organic solvent is N-methyl-2-pyrrolidone and/or amine solvent with boiling point of greater than or equal to 150 degrees C e.g. 3-amino-1-propanol.
