ABSTRACT:
The object of the present invention is to provide a method of producing electric cells which can improve the production yield, and for that purpose there is provided a method of producing an electric cell, wherein an acidic solution as an electrolytic solution and electrically conductive rubber as an exterior material are used, characterized in that sealing both of the positive electrode and the negative electrode piled via the separator with both of the gasket, through which the stainless needle is inserted, and the electrically conductive rubber, performing a vulcanization binding, after said vulcanization binding, forming a hole by pulling off the stainless needle from the gasket, injecting the electrolytic solution through said hole and sealing said hole; thus obtaining electric cells at high production yield.
