In FIG. 3, 21 is a sealing plate that also serves as a negative electrode terminal made of stainless steel, 22 is a battery case that also serves as a positive electrode terminal made of stainless steel, 23 is a gasket made of polypropylene, 24 is manganese dioxide, a conductor and a binder. outer diameter phi 5 of disc-shaped positive electrode obtained by forming a positive electrode mixture composed of 25 at the negative electrode, and a metal lithium plate active material.

々な弊害を生じる。According to the above conventional proposal, the expansion of the disk-shaped positive electrode 24 can be released in the longitudinal direction of the battery against the reduction in the thickness of the lithium negative electrode 25 caused by the discharge. The degree of tightness inside the battery was kept good, and abnormal discharge due to insufficient contact pressure could be effectively suppressed.
On the other hand, however, the positive electrode 24 expands intensively in the vertical direction due to the discharge, and hence the height of the battery swelled beyond the initial assembly dimension from the time when the discharge depth exceeded 50% of the capacity. The increase in the height of the battery depends on the magnitude of the discharge current, but when it is large, it reaches 0.3 to 0.5 mm. This increase in the battery height causes various harmful effects when used by being incorporated in a device.

Further, when the height of the battery increases greatly, the sealing plate 21 also serving as the negative electrode terminal and the battery case 27 also serving as the positive electrode terminal are greatly deformed, and the caulked portion of the gasket 23 is distorted, so that the liquid leakage resistance is extremely high. It got worse.

The thickness of the lithium negative electrode decreases due to discharge, but the positive electrode responds by expansion of the molded body in the vertical direction,
Further, the plateau-shaped flat portion (10) of the inner case of the battery pushes up the positive electrode molded body by the spring action, so that the molded body presses the separator and makes good contact with the lithium negative electrode surface. This action maintains the degree of tightness inside the battery.
