POSITIVE ELECTRODE FOR BATTERY

PURPOSE:To facilitate the infiltration of an electrolytic solution into open holes and increase the output by molding a positive electrode forming material mixed with the electrolytic solution or an electrolyte so as to form open holes. CONSTITUTION:An electrolytic solution or an electrolyte 7 is mixed and kneaded with an electrode active material 4 serving as a positive electrode forming material, binder 6, and a current collector 5 to mold a positive electrode 2. The surface of a current collecting plate 9 is coated with a hard paste 8, then a plate 10 hardly stuck with the paste 8 is mounted on it, and the pressure 11 capable of generating necessary open holes is applied from the above to compress and mold it. Since the electrolytic solution or the electrolyte is kneaded together with the conventional positive electrode forming material, open holes are well wetted by the electrolytic solution, the electrolytic solution and the electrolyte easy to be wetted exist on open holes, thus the electrolytic solution easily infiltrates into the positive electrode when a battery is constituted. Accordingly, the contact face between lithium ions and the electrode active material 4 is increased and intercalation is facilitated, and the output of the battery is increased.
