じることがあった。However, graphite in the positive electrode mixture plays a role not only as a conductive agent but also as a release agent at the time of molding the positive electrode mixture. The friction between them increases. Due to the frictional force, the mold is worn out intensely, and the mold is frequently replaced. In some cases, the mold itself may be damaged, which causes a great problem not only in manufacturing but also in cost. There was something.

じることが分った。However, when a metal mixture of stearic acid is added and mixed at the time of mixing the positive electrode material and then the granular mixture is granulated and the positive electrode mixture is press-formed, the release agent In order to obtain a sufficient effect, it is necessary to add a large amount of a metal salt of stearic acid.
However, in this case, the water repellency of the metal salt of stearic acid deteriorates the liquid absorbing property of the molding mixture, and when the alkaline electrolyte is injected in the subsequent battery manufacturing process, a part necessary for battery design is required. It has been found that it takes a long time to absorb a fixed amount of the electrolyte solution into the positive electrode mixture, resulting in a disadvantage that productivity is reduced.

When 200 ppm of zinc stearate is added, the effect as a release agent starts to appear, and when it is 2,000 ppm or more, it becomes very good. On the other hand, when the amount of zinc stearate added exceeds 2,000 ppm, the liquid absorption starts to decrease rapidly, and it becomes difficult to maintain the amount of electrolyte required for battery design. In addition, the discharge result becomes worse rapidly when the added amount of zinc stearate exceeds 2,000 ppm in conjunction with the amount of the electrolytic solution.

な方法でも実用化は困難である。Although not described in the present embodiment, graphite is added in an amount of 2 to 12% by weight based on manganese dioxide.
The same investigation was performed on the granular mixture in which the amount of addition was changed by weight%. As for the amount of liquid absorption, when the graphite content exceeded 2,000 ppm as in this example, the liquid absorption rapidly increased. It was confirmed to be worse. With respect to the releasability, when the amount of graphite relative to manganese dioxide was more than 10% by weight, it was good without adding zinc stearate, and the necessity of adding zinc stearate was not recognized. When the amount of graphite with respect to manganese dioxide is reduced to 2% by weight, even if 3,000 ppm of zinc stearate is added, the releasability is poor, and practical use is difficult even with the method of the present invention in consideration of the liquid absorption. is there.

By adding and dispersing stearic acid or a metal salt of stearic acid after the granulation step of the granular mixture and segregating it on the surface of the granular mixture, it has a sufficient function as a release agent with a small amount of addition In addition to reducing the wear of the mold and reducing the frequency of changing the mold, which is advantageous in terms of cost, the graphite content is reduced and the content of manganese dioxide, which is the active material, is increased. It is easy to improve performance. Furthermore, since a small amount is added to the surface of the granular mixture, and since there is no stearic acid or a metal salt of stearic acid inside the granular mixture, the effect of its water repellency can be minimized. A predetermined amount of electrolyte required for battery design can be promptly absorbed by the positive electrode mixture without substantially reducing the liquid absorption of the pressed positive electrode mixture. Therefore, a high-performance zinc alkaline battery can be provided.
