PROBLEM TO BE SOLVED: To provide a battery whose high rate discharge capacity is large, by inserting specific amount of lithium-ion-conductive inorganic solid electrolyte into a non-conductive solid polymeric porous film, and filling lithium-ion conductor into holes of this porous film. SOLUTION: By filling a lithium-ion conductor such as a compound of polyacrylate and LiClO4 into holes of a non-conductive solid polymeric porous film such as polyolefin resin film, fluororesin film, polyester resin film, and acrylic resin film, a lithium-ion-conductive polymeric electrolyte film is provided. Using positive electrode active material such as this polymeric electrolyte film and MnO2 , and negative electrode active material such as graphite, a lithium battery is constituted. Lithium-ion-conductive inorganic solid electrolyte in 20-65 wt.% of the entire amount is inserted into the solid polymeric porous film. The inorganic solid electrolyte is preferably LiN3 , LiTi2 (PO4 )3 , or the like. Therefore, lithium-ion-conductivity of the polymeric electrolyte film is improved. |
