Recently, a method of filling an active material into a foam metal having a high porosity and a continuous three-dimensional network structure has become mainstream. After filling the foamed metal with an active material by a known method, it is temporarily dried to remove excess active material adhering to the surface, pressurized, and subjected to post-treatments such as surface treatment to obtain an electrode plate. The original plate of is manufactured.

る。Here, although it is necessary to attach a lead to this electrode, the following method is generally known because it is difficult to weld a lead to a foam metal filled with an active material. As shown in FIG. 7, a pressing press roll (2) is passed through one end of the foam metal (1) before being filled with the active material to form a crushed portion (3) obtained by crushing the foam metal in its thickness direction. Let After that, the foamed metal is filled with the active material, but the uncrushed portion is filled with the active material, whereas the crushed portion is not filled with the active material. Therefore, the lead plate (5) can be welded to this portion.

もない。The problems at this point are as follows. After the lead is welded to the electrode plate that has been filled with the active material, dried, and pressed, there are several additional steps to complete the battery. In those steps, when the electrode plate is transported, stored, etc. It is unavoidable that external force is applied to the lead. On the other hand, the electrode plate before the active material is filled, that is, the metal foam itself is a flexible material, but when the active material is filled, and the drying and pressing steps are performed, the material becomes a hard but brittle material. That is, in the vicinity of the welded portion of the lead of the electrode plate, inconveniences such as cracking or chipping of the electrode plate or dropping of the active material are likely to occur. It goes without saying that it causes deterioration of battery performance.

As long as the entire inclined surface (8) is filled with the active material, cracks, chips and the like cannot be prevented due to the property that the electrode plate is hard and brittle. Rather, near the tip of the inclined surface (8) (9)
Is likely to be bent by external force as shown in Fig. 10,
The possibility that the active material will fall off will increase.

In a welded electrode, a non-filled region not filled with an active material is provided in a thickness direction between a crushed portion for welding a lead plate and an active material filled portion. . And, the non-filled region may include an inclined surface, or all of the inclined surface,
Alternatively, it is effective to form a part of the inclined surface.

A boundary line (L) between the active material filling portion (4) and the non-filling region of
That is, in this case, the tip of the lead plate (5) was positioned at the step (6) at a right angle between the crushed portion (3) and the non-crushed portion and fixed by welding. On the other hand, in the present invention, on the other hand, in this case, as shown in FIG. 6 (b), the tip of the lead plate (5) is positioned at the right-angled step (6), but the position of the boundary line (L) is lowered so that the non-crushed portion of the active material is The non-filling area (7) is formed.

悪影響を及ぼさなくすることができる。In this way, the lead plate is welded and fixed to a part of the foam metal, and a non-filled region where the active material is not filled, that is, a flexible buffer region is provided around the lead plate, and this buffer region leads. The external force applied to the plate and the deflection of the lead plate can be absorbed, and the hard but brittle active material filling region of the electrode plate can be prevented from being adversely affected.

A crushed part (3) was prepared by crushing. Although the crushed portion (3) shown in FIG. 7 is generally known, the crushed portion (3) as shown in FIG. It is desirable to secure the active material-filled portion to the maximum by minimizing the requirement 3). At the same time that the crushed portion was formed by pressing, an inclined surface (8) was formed at the boundary between the crushed portion (3) and the active material filled portion (4).

の境界は図３に示すように傾斜面（８）である。Next, the foam metal plate (1) is filled with an active material. At this time, in the crushed portion (3), the pores inside the foam metal (1) are crushed, so that the active material is not filled. Also, the inclined surface (8) formed by pressing is not filled with the active material in the vicinity of the crushed portion (3) because the pores inside the metal foam plate (1) are crushed. Thereafter, as shown in FIG. 2, the lead plate (5) is welded to the crushed portion (3), and the area of the crushed portion (3) is fixed by welding to the crushed portion (3) of the lead plate (5). The non-filled region (7) not filled with the active material was provided between the edge of the lead plate (5) and the active material filled portion (4) by setting the area larger than the contact area with. The non-filled region absorbs the external force applied to the lead plate (5), the deflection of the lead plate (5), etc., so that the active material filled portion (4) is not adversely affected. The boundary between the active material filled portion (4) and the non-filled area (7) is an inclined surface (8) as shown in FIG.

一層大きくなる。Further, in the above embodiment, the inclined surface (8) is provided around the crushed portion (3), but the inclined surface (8) also has a non-filled region in which the active material is not partially filled. Is as described above. In this non-filling region, the taper is tapered so that the concentration of the external force is relieved, and the effect of absorbing the external force is further increased.

（８）でも上記効果が期待できるようになる。When the inclined surface (8) is formed by cutting instead of pressing, unlike the pressing, there is no collapse of the pores in the foam metal on the inclined surface (8) and the active material is The entire inclined surface (8) is filled. Therefore, the effect of absorbing the external force at the tapered portion cannot be expected as it is. Therefore, if a part or all of the active material of the inclined surface (8) is removed by an appropriate method such as ultrasonic waves, the above effect can be expected even with this inclined surface (8).

The inclined surface (8) shown in Fig. 4 is divided into a lower inclined surface (8 ') and an upper inclined surface (8 ") as shown in Fig. 4 and then filled with an active material. A non-filled region (7) in which the active material is not filled is crushed by a pressure press to form a flat surface in the gap 8 ') (8 ").
And Thereafter, the lead plate (5) was welded and fixed to the crushed portion (3) to prepare a battery electrode.
