    摘要： An electrode body of a secondary battery is formed by superimposing a positive electrode and a negative electrode upon each other with a belt-shaped separator interposed between the electrodes, and rolling up the positive and negative electrodes and the separator into a spiral shape. At least one side edge of a positive electrode current collector of the positive electrode in the longitudinal direction thereof includes a plurality of step parts discontinuously formed in the longitudinal direction at unequal intervals, and extends at both sides of each step part with a deviation of 0.2 mm or more. At least one side edge of a negative electrode current collector of the negative electrode in the longitudinal direction thereof includes a plurality of step parts discontinuously formed in the longitudinal direction at unequal intervals, and extends on both sides of each step part with a deviation of 0.2 mm or more.

    摘要： An object of the present invention is to improve the alkaline dry cell performance by modifying a positive cell case. An alkaline dry cell comprises a can as both of a terminal and a cell case 1 for accommodating a power generating element, prepared by drawing processing of a cold rolled steel material preliminarily applied with nickel-plating on both sides so as to form a can, having a conductive film formed in an inner surface portion contacting with a positive electrode compound, wherein the area of the portion with the conductive film is in the range of 75% to 90% with respect to the area of the whole portion contacting with the positive electrode compound in the inner surface. Since the conductive film is provided, the increase of the contact resistance can be prevented so as to improve the short-circuit current and the storage property. With less than 75% conductive film area, the above-mentioned effect cannot be achieved sufficiently. On the other hand, with more than 90% area, the filler compound can be separated in the dry cell production. Therefore, the above range is appropriate.
