極間の接触状態が不良となり、特に電池の衝撃試験によ
って内部抵抗が高くなるという問題点があった。Problems to be Solved by the Invention As described above, button-type batteries, especially thin button-type batteries, have thin terminal plates, so unless the filling volume ratio of the active material in the terminal plate is reduced, Immediately after filling, the active material may protrude due to a slight impact. Therefore, in a thin button-shaped battery having a flat terminal surface as described above, the filling volume ratio of the active material in the terminal plate is 80 to 88%, and it has not been possible to increase the filling volume ratio any higher. Therefore, inside the battery shown in FIG. 2(b), the active material 2 made of zinc faces the surface of the impregnating material 3, the surface of the separator 4 in contact with the lower side thereof,
In addition, the elastic pressing force applied to the surface of the positive electrode mixture 6 that is in contact with the lower side is weak, and the impregnating material 3. There was a problem in that the contact condition between the positive electrode and the negative electrode through the separator 4 was poor, and the internal resistance became high especially when the battery was subjected to an impact test.
本発明は上記問題点に鑑み、セパレータを介した正極、

It is an object of the present invention to provide a button-shaped battery that can improve the contact state between negative electrodes and eliminate deterioration of battery characteristics caused by impact tests.
問題点を解決するための手段 この目的を達成するため、本発明の電池は、正。Means to solve problems To achieve this objective, the battery of the present invention uses a positive battery.
負いずれか一力価の端子板においてその端子面の外周部

、従来より内容積が小さくなる。Function: With this kind of battery, even if the terminal surface shape changes, the height and outer diameter of the terminal plate can be maintained at the same level as before, and even immediately after filling the terminal plate with active material, if the filling amount is the same as before, there will be no protrusion. Does not occur. Moreover, after the battery is configured, in order to make the total battery height the same, the terminal board is recessed into the battery by the volume (the ring-shaped part that is the middle area between the outer periphery and the center of the terminal surface). The product becomes smaller.

。Therefore, even if the active material filling amount is the same as in the past, the filling volume ratio of the active material in the terminal board can be increased to nearly 100%, and the filling volume ratio of the active material in the terminal board can be increased to nearly 100%. The elastic pressing force applied to the counter electrode mixture surface in contact with the lower side is increased, and the contact between the positive electrode and the negative electrode via the impregnating material and the separator is made good without loosening.
Deterioration of battery characteristics due to impact tests can be prevented.
