露出し、しかも内骨1と充填した活物質ペースト4との
間に隙間5を生じる。However, the strength of the lattice body is decreasing as the thickness of the lattice body is reduced, and the inner bone 1 is deformed by the pressure applied when the lattice body is filled with the active material paste, and the inner bone 1 is deformed. Is pushed down to. As a result, as shown in FIG.
The inner bones are partially exposed on the surface of the electrode plate without sufficiently wrapping around to the back side of the above, and a gap 5 is formed between the inner bones 1 and the filled active material paste 4.
このような極板では、内骨1が活物質層の中央になく
偏在していることから、化成中に極板が湾曲したり、電
池使用中にも活物質の反応分布が不均一になって、充放
電サイクル寿命が短かくなる原因となる。In such an electrode plate, since the inner bone 1 is unevenly distributed in the center of the active material layer, the electrode plate is curved during formation, and the reaction distribution of the active material becomes non-uniform even during battery use. As a result, the charge / discharge cycle life becomes short.

が反対面にまで達することなく途中で止まる。そして、
内骨の裏側まで、充填されたペースが十分に回り込む。Operation In the lattice body according to the present invention, since the internal bone has an arched shape in which the internal bone is convex on the center line of the lattice body which is most deformed under the pressure when the active material paste is filled, the internal bone is not deformed. Stops halfway without reaching the other side. And
The filled pace wraps around to the back of the inner bone.

生じなかった。FIG. 2 shows a state in which the lattice material is filled with the active material paste 4 from the side where the inner bones 1 are convex. The inner bone 1 is deformed by the paste filling pressure and the whole is located in the center of the active material layer. When this electrode plate was formed, the reaction distribution was uniform because the inner bone 1 was in the center of the active material layer, and the electrode plate was not curved.
