PURPOSE: To restrict the crystallization tendency with lowering of temperature, and to make possible the operation of battery at any temperature by using polymer electrolyte, which includes the complex of polymer and alkali metal salt, as the polymer electrolyte to be used for solid electrochemical battery, and generating cross-linking of the polymer so as to transform the polymer from solution to gel. CONSTITUTION: Polymer electrolyte, which includes the complex of polymer and alkali metal salt, is used, and the polymer forms a donor-acceptor type connection with the alkali metal ion, and the polymer electrolyte, which can transmit the alkali metal ion, is irradiated so as to manufacture the solid polymer electrolyte. At the time of manufacturing this polymer electrolyte, cross- linking of the polymer is generated so as to transform the polymer from solution to gel, and the transformation of the polymer from amorphous to crystal is performed by using the solvent in response to the condition and kind, and the polymer electrolyte is irradiated in the solution condition. As a solution, aqueous solution is used, and as a gel, hydro gel is used. Polymer electrolyte is irradiated withγ-ray or electron beam. |
