ABSTRACT:
Corner region vacancies resulting from insertion of a spiral electrode unit into a prismatic can are fully utilized to reinforce the can and produce superior battery characteristics. A non-circular spiral electrode unit is made by rolling a negative electrode-separator-positive electrode sandwich. A prismatic shaped can has corners which are thicker than the straight-line regions of the can. The can houses the the electrode unit In a tightly sealed fashion with the outer winding of the electrode unit mechanically held in electrical contact with the can.
