る。 Generally, in both alkaline electrolyte batteries and organic electrolyte batteries, thin batteries have an anode can and a cathode terminal plate that fit together through packing that contacts the inner bottom surface of the anode can in order to reduce the total height of the battery. It has a unique structure. This assembly involves positioning a cathode terminal plate with an annular gasket fitted around its periphery with its outer surface facing down, filling the concave part of the cathode terminal plate with a paste-like cathode agent, and
A thin absorber plate, an annular insulator, a separator, etc. are placed on top of it in order, and finally a disc-shaped anode mixture is placed on top of it, and an anode can is placed over the whole to cover it, with the open end turned inward. It is usually curled and sealed.

There are many cases where the thickness of the battery is uneven and the product value is lost.
Furthermore, since the battery has a large number of component parts, assembly work is extremely complicated.
