It was l. In addition, good and uniform filling was observed, and the active material was strongly bonded to the network structure of the substrate, with almost no dropout of the active material due to vibration or the like. In order to solve this problem, according to the conventional method, a three-dimensional reticular strip plate made of the same material with a thickness of 24 mm was filled with the active material-containing paste using a pair of four-layers for filling active material paste, and then immediately heated and dried. An electrode plate manufactured by compressing it with a pair of pressure soles with a thickness of 1@s has a filling amount of active material of α129 (0(10) /
It was d. Regarding the filling state of the active material, good filling was observed in the surface layer portions on both sides of the compressed plate, but the amount of active material packed in the inner center layer was extremely small. However,
The bond between the active material and the substrate structure was weak, and it was observed that the active material easily fell off due to vibration or the like.

Therefore, compared to the conventional method, the amount of active material filled is increased, and the active material can be evenly filled to the center of the compressed plate.Next, this compressed plate is heated and dried. , it is possible to avoid inconveniences such as separation of the active material from the three-dimensional network substrate and subdivision, which occur when converting the plate after drying the conventional active material. It can be dried in close contact with the tissue substrate.
It is obtained as a filled active material that is firmly bound to the substrate, and therefore has the effect of extending the life of the electrode plate.
