Description of the Related Art Conventionally, for electrodes used in alkaline storage batteries such as nickel-cadmium storage batteries, nickel salts and cadmium are deposited on a porous sintered substrate obtained by sintering nickel powder using a punching metal as a conductive core. There is a sintering method in which a solution such as salt is impregnated and treated with an alkali to make it an active material. On the other hand, there is a non-sintering manufacturing method in which a paste-like active material is directly held on a three-dimensional porous metal plate such as a conductive core, a metal fiber sintered body, or foamed nickel.

あり、生産性が低下するという欠点を有していた。Incidentally, as a method of attaching the collector terminal to each electrode, there is a method in which the collector terminal portion 2 is provided in advance on the core body 1 of the electrode as shown in FIG. However, according to this method, the part 3 of the core body excluding the collector terminal portion 2 is not required, which is a material loss, and the step of forming the collector terminal portion 2 in advance and punching it out is complicated by changing the model. Therefore, there is a drawback that productivity is lowered.

接で集電端子を溶接する方法がある。Further, in order to eliminate material loss and improve productivity, after cutting the electrode plate into a desired size, a part of the active material layer of the electrode plate is peeled off to expose the surface of the conductive core. There is a method of mounting a current collecting terminal on the exposed surface and welding the current collecting terminal by electric welding with a pair of welding electrodes composed of an upper surface of the current collecting terminal and an opposite surface on which the current collecting terminal is mounted.

下するという欠点を有する。However, in this method, the peeling of the active material layer becomes insufficient, and when foreign matter remains between the welding electrodes, the active materials such as nickel hydroxide and cadmium hydroxide and the binder are Since the conductivity is extremely poor, sufficient conduction cannot be obtained between the welding electrodes, and sparks are likely to occur, which makes welding difficult. Therefore, there is a drawback that the production efficiency and the reliability of welding are reduced.

れている。In order to solve these drawbacks, Japanese Patent Publication No. 54-31575 discloses a method of attaching a collector terminal.
An edge of each predetermined electrode plate is projected on each of the upper and lower end faces of an electrode body formed by inserting a separator between the negative electrode plate and these electrode plates, and a myriad of convex portions are formed on the surface mounted on the edge. A method has been proposed in which a current collecting terminal made of a perforated metal plate having a hole is fixed by electric welding with a pair of welding electrodes abutting on the current collecting terminal.

ない端縁を設け、陰、陽極板をずらして捲回しなければ

るという欠点を有している。However, in this method, since the convex portion of the current collector terminal is hard to be embedded in the edge of the electrode plate, in order to prevent a short circuit between the shade and the anode plate, the edge without the active material layer having a width of about 1 mm is formed. And the negative and positive plates must be displaced and wound. Therefore, it has a drawback that the volume energy density of the electrode plate is lowered.

とを特徴とするものである。A method for manufacturing an electrode plate for an alkaline storage battery according to the present invention is a method in which an active material layer of an electrode plate having an active material layer formed on a conductive core is subjected to ultrasonic waves in a direction perpendicular to the surface of the conductive core. Peel by applying vibration to expose the surface of the conductive core, place the collector terminal on the part of the electrode plate from which the active material layer has been separated, press the ultrasonic horn from the top, and place it horizontally against the surface of the conductive core. It is characterized in that the current collecting terminal is welded by applying ultrasonic vibration in the direction.

不良となる場合がある。[Operation] When a current collector terminal is placed on the core body surface from which the active material layer has been peeled off and the current collector terminal is welded by resistance welding, if foreign matter remains between the core body surface and the current collector terminal, sparks or the like will occur. May result in poor welding.

が上述の条件を満足していることを見出した。According to various experiments conducted by the inventor, it has been found that the welding method using ultrasonic vibration in the horizontal direction can provide a highly reliable welding state even if some impurities remain on the welding surface. Further, it was found that the peeling of the active material on the back surface of the core body is not necessary and the removal rate of the active material on the welded surface is as high as possible, which is a factor for obtaining a good welded state. Based on these results, as a result of various studies on the peeling method of the welded portion, it was found that the active material removing method by ultrasonic vibration in the vertical direction satisfies the above conditions.

を防止する事が出来る。When an alkali-resistant resin adhesive tape is attached to the opposite surface of the electrode plate to which the current collecting terminal is welded, the rough active material surface may penetrate the separator or the active material may fall off. Since nothing happens, it is possible to prevent an internal short circuit during winding.

ない。Further, when the area of the pressing surface (hereinafter abbreviated as a chip) at the tip of the ultrasonic horn that presses the current collecting terminal is made larger than the area of the current collecting terminal, the end of the current collecting terminal warps and the separator is removed. There is no danger of penetrating and causing an internal short circuit.

The pressure was changed between 5 × 10 4 Pa and 9.0 × 10 4 Pa, and ultrasonic vibration with a horizontal frequency of 20 kHz and an amplitude of 60 μ was applied to the conductive core for 0.5 seconds, and the above-mentioned collection was performed. Welded the electrical terminals. The results of examining the tensile strength of the welded portion at this time are shown in FIG. The value in the figure is 1
