かることができる。In Figure 1 on page 2, 1 is a positive electrode current collector with nickel plating 1B on both sides of an iron plate, and a positive electrode container that also serves as a positive terminal; 2 is a single metal such as silver oxide, silver peroxide, manganese dioxide, mercury oxide, etc. or a mixture, or a positive electrode mixture to which a conductive agent such as carbon is added, a positive electrode ring that supports the 3u sealing force, 4 a separator, 6 a liquid-containing material, 6 a seal made of nylon, 1 co-packing. , 7 is a stripped negative electrode composed of an aqueous solution mainly composed of frozen zinc powder, a thickener, caustic potash, and caustic soda, and 8 is a negative electrode container. When trying to increase the capacity of conventional batteries, one method is to improve the formulation of the positive and negative electrodes, but there are also ways to increase the capacity by reducing the thickness of the container and increasing the internal volume even with the same external dimensions. It can be measured. For example, diameter 9.5
jff, silver oxide electrolyte oil 5R920 with a thickness of 2,011 mm,
By changing the thickness i of the positive electrode container used from 0.20 ff to 0.16 mm, the capacity can be increased by about 6%.

有していた。Page 3 However, with the conventional positive electrode container material, which is an iron plate plated with nickel, sufficient mechanical strength cannot be obtained if the plate thickness is 0.15 gg or less. Due to this poor caulking, when the battery is sealed, the bottom of the positive electrode container may swell and exceed the predetermined total height of the battery, or a void may be created inside, causing the internal resistance of the battery to vary. Furthermore, the caulking structure of the B portion, which is the opening of the container, became unstable, and the Mt liquid properties also deteriorated.
