Specifically, it relates to the substrate and the edge of the electrode plate of the collector plate.

Description of the Related Art In an electrode plate for an alkaline storage battery in which a sponge-like metal porous body is used as a substrate and the active material is filled in the substrate, a part of the active material filled in the substrate is removed by an ultrasonic peeling machine or the like. , The current collector plate was welded to that part. Such an electrode plate has conventionally had the following problems.

う。First, when a sponge-like metal porous body having a low metal density is used as a substrate, the active material is filled in a large amount and the energy density increases, but the strength of the substrate decreases. As described above, when the strength of the substrate is low, there is a problem that the welding is difficult or impossible when the current collector plate is welded. On the other hand, if a sponge-like metal porous body having a high metal density is used as the substrate, the strength of the substrate is improved and the current collector plate can be easily welded, but the filling amount of the active material is reduced and the energy density of the electrode plate is reduced. Will fall.

電板溶接部の補強を行なっていた。According to this method, since the strength of the welded portion of the substrate is improved, the welding can be easily performed. Moreover, since the strength of only the welded part is improved,
Since the metal density of the other partial substrates remains low, the filling amount of the active material does not decrease.

Has become. On the other hand, when the battery is vibrated at the portion where the end edge portion of the current collector plate of the electrode contacts, the current collector plate vibrates with the end edge of the current collector plate as a fulcrum. The part of the electrode plate where the end edge of the current collector comes into contact corresponds to the boundary between the part where the substrate strength is improved and the part where the substrate strength is not improved, or the part where the strength is not improved. When it is applied to the part, the strength is low, and the electrode plate is cut.
