PURPOSE:To make performance uniform and improve adhesion of positive active material with a current collector by making ink with a positive mix and organic solvent, inking a current collector, and drying to form a positive electrode. CONSTITUTION:A positive mix ink is applied to a positive current collector 2 by screen printing, and dried to form a positive electrode 4. The current collector 2 is required to be stable against positive active material, electrolyte, and organic solvent. therefore, for example, a film obtained by laminating an aluminum foil on a conductive film prepared by dispersing carbon filler in polyolefin resin is used as the current collector. Thereby, adhesion of positive active material with current collector is increased and performance of the battery is made uniform. |
