Abstract

PURPOSE:To increase the close contacts between a positive can and a plural number of ring-like positive mixtures, and reduce the internal resistance of a cylindrical alkaline battery by performing compression twice or more in making the positive mixtures to closely touch the inner wall of the positive can by compression work after the positive mixtures are stacked in the positive can. CONSTITUTION:A plural number of temporarily-molded ring-like positive mixtures 1a-1d, are stacked in a positive can 2. Next, a core rod 21 is fitted into the hollow center of the positive mixtures 1a-1d, and the mixtures 1a-1d are pressed from above with an upper pounder 22 so as to make the inner wall of the positive can 2 in close contact with the positive mixtures 1. Here, the mixtures 1a-1d are pressed twice or more in such a manner that the mixtures 1a and 1b are stacked together and pressed before the positive mixtures 1c and 1d are stacked over the mixtures 1a and 1b and pressed. After that, a separator 3 and a negative agent 4 are packed in the hollow center so as to constitute a cylindrical alkaline battery. By the means mentioned above, the close contacts between the positive can 2 and the positive mixtures 1 can be homogeneously increased. Besides, the short circuit current of the battery can be increased by reducing the internal resistance of the battery.

壁に密着させることが行なわれている。In cylindrical alkaline batteries such as alkaline manganese batteries, in order to make close contact between the positive electrode mixture and the positive electrode can, the positive electrode mixture is temporarily formed into a ring shape as shown in Japanese Patent Publication No. 55-20834. A predetermined number of the positive electrode mixtures are stacked along the inner wall of the can, a core rod is inserted into the hollow part of these positive electrode mixtures, and an upper punch slidably attached to the outer periphery of the core rod is used to punch the negative part of the positive electrode mixture. The positive electrode mixture is compressed between the positive electrode can and the core rod so that it is brought into close contact with the inner wall of the positive electrode can.

ルカリ電池を提供できるようにしたものである。The present invention was made in light of such a situation, and consists of stacking a predetermined number of temporarily formed ring-shaped positive electrode mixtures along the inner wall of a positive electrode can, and filling the hollow portions of these positive electrode mixtures. A core rod is inserted into the core rod, and an upper punch slidably attached to the outer circumference of the core rod applies pressure from above to the positive electrode mixture, compressing the positive electrode mixture between the positive electrode can and the core rod and tightly contacting the inner wall of the positive electrode can. In manufacturing cylindrical alkaline batteries, the positive electrode mixture on the bottom side of the positive electrode can is mixed with the positive electrode mixture on the upper side, that is, the opening side of the positive electrode can, by applying pressure with an upper punch in two or more times. Similarly, sufficient pressure can be applied to improve adhesion to the inner wall of the positive electrode can, thereby making it possible to provide a cylindrical alkaline battery with low internal resistance.

Alternatively, you can first insert two ring-shaped positive electrode mixtures in a stacked manner and pressurize them with an upper punch. It is also possible to stack them and pressurize them with an upper pestle.
