The alkaline storage battery has many excellent characteristics in such as large current discharge, low temperature and long life and has been adopted in various fields.
There are two types based on the electrode plate structure, one is a pocket type and the other is sintered type; it is possible to select each of the types. The pocket electrode plate makes excellent the storage battery in mechanical strength, due to a small box (a pocket) made of perforated thin steel plate filled with active material and conductive auxiliary material. The sintered electrode plate, which is filled with active material in the fine pores of the porous base made by sintering nickel powders in reducing atmosphere, configures the excellent storage battery in high rate discharge and low temperature characteristics.
The stationery alkaline storage battery is classified as follows based on the characteristics of structure and electrode plate type.
| Seal type | |
