PROBLEM TO BE SOLVED: To provide a lithium battery which is high in stability, preserving excellent discharging characteristic at low cost, by making the electrolyte to dissolve lithium perchlorate a gel electrolyte consisting of a high polymer solid electrolyte and an organic solvent. SOLUTION: A manganese dioxide is used for positive electrode active material, and ketchen black is used as a conductive material, and a substance where a polyethylene oxide and a functional acrylic acid ester are mixed as binders is used as a composite positive electrode 2. As the negative electrode active material of the battery, lithium metal 4 is used, and this is made to pressure contact with the negative electrode collecting plate of a stainless steel foil. For an electrolyte layer 3, a substance where γ-butyrolactone, polyethylene oxide, and function acrylic ester are dissolved with one another, and lithium perchlorate is dissolved to it is applied on the negative electrode, and it is irradiated with an electron beam to form a gel electrolyte layer. Hereby, a lithium battery high in safety can be obtained. |
