It is an object of the present invention to provide the above battery that can be easily and reliably positioned.

口端を内方へカールして封口するのが普通である。However, in recent years, the demand for thin batteries has been increasing due to their smaller size and lighter weight.
The structure is such that the anode can and the cathode terminal plate are fitted through a gasket that contacts the inner peripheral surface and inner bottom surface of the anode can, and there is sufficient protection against liquid leakage from the contact surface between this gasket and the anode can. Currently, no countermeasures have been found yet.
For example, on the inner surface of the anode can that contacts the gasket,

This is time-consuming and reduces the workability of assembly.On the other hand, in general, when assembling this type of battery, a cathode terminal plate with an annular gasket with an L-shaped cross section fitted around its periphery is placed with its outer surface facing downward. Fill the concave part of the cathode terminal board with a paste-like cathode agent, place the absorber thin plate, ring-shaped insulator, separator, etc. on top of it in order, and finally place the disk-shaped anode mixture. It is common practice to place an anode can over the entire container and curl the open end inward to seal it.

づいて説明する。However, it is very difficult to place the anode mixture in the center of the battery due to the fact that the battery itself is small, and even if it can be placed in the center, it may rub due to the pressure during sealing. This often happens, and the thickness of the battery J may be uneven, which may impair its commercial value. In the above thin battery, a liquid packing impregnated ring having an inner diameter approximately equal to the diameter of the anode mixture and an outer diameter approximately equal to the inner diameter of the bottom of the anode can is disposed between the inner bottom surface of the anode can and the bottom surface of the gasket. By doing so, leakage of liquid at the contact surface between the anode can and the gasket is sufficiently prevented, and the center positioning of the anode mixture during battery assembly is made easy and reliable. Hereinafter, the present invention will be explained with reference to the drawings regarding an alkaline electrolyte battery.

Leakage from the contact surface between the anode can and the gasket is sufficiently prevented. FIG. 3 shows one step in the assembly process of the battery of the above example, in which a gasket 3 is fitted around the periphery, a cathode terminal plate 2 is filled with a cathode agent 5, and an absorber 9 is placed on top of the cathode agent 5.
, an insulator 11, a separator 10, and a liquid backing impregnated ring 4 are placed thereon.
The anode mixture 8 is fitted into the hole as shown in the figure.

The table below shows the leakage resistance test results and anode mixture misalignment accident of Battery A of the present invention, which used a paper ring impregnated with asphalt pitch as a liquid backing impregnated ring, and Battery B, which did not use any ring. This shows the incidence rate.

。In addition, the leakage in the table is the result of the contact between the anode can and the gasket when 5 rails each of Battery A and Battery B, which did not shift in position, were left in an atmosphere of 60°C and 90% relative humidity for 20 days. This is the number of batteries that were found to be leaking from the surface, and the positional deviation is the number of batteries that are uneven in total height when batteries with 5 fences are assembled based on the respective configurations of Battery A and Battery B. It is the number of pieces. From the table above, it can be seen that the battery of the present invention has excellent leakage resistance, and the occurrence of misalignment of the anode mixture during assembly is extremely rare.
