ある。Conventional technology and its problems Conventionally, the substrates of the so-called sintered and paste type electrode plates for alkaline batteries have been made of nickel-plated perforated steel plates or expanded steel plates.
Metal, nickel net, foamed nickel sheet, or a microporous material called nickel plaque, which is made by sintering fine nickel powder on a suitable support, is used.
These were filled with negative and positive active materials using an appropriate method to form electrode plates. Relatively recently, instead of these substrates, metal fibers made of iron, nickel, or stainless steel have been made into a felt shape, which is then sintered or nickel-plated as required, and an anode or a cathode active material is attached to this substrate. , a method of preparing an electrode plate by filling with a paste method, an electrodeposition method, a chemical reaction precipitation method, etc. has been proposed. However, there is a problem with forming ears for current collection on these electrode plates, and it is not possible to weld metal pieces for current collection as is, and even if welding is possible, the strength is too weak to be practical. . Therefore, conventionally, as shown in FIG. 1 (a), a plan view of a metal fiber substrate, and (b), an enlarged cross-sectional view taken along the line A-A', the necessary portion 2 of the substrate 1 before being filled with active material is pressed under high pressure to make it denser, and that portion is It was common practice to attach and reinforce a thin metal plate 3 by welding to form an ear part, to assemble this pole plate in a spiral shape, and to weld a current collecting metal piece 4 as shown in FIG. However, in order to actually mass-produce such electrode plates, extremely long thin metal plates must be welded continuously and accurately, which is quite troublesome and disadvantageous in terms of cost.

ろ若干優れた成績が得られている。 If necessary, the entire body may be sintered by heating to 900 to 1100°C for a short time, and if iron fiber is used, nickel plating may be applied.
In the case of a cathode plate, this substrate is coated with an active material made of powder mainly composed of cadmium oxide and made into a paste with an appropriate liquid, and in the case of a cathode plate, a powder mainly composed of nickel hydroxide is pasted. The active material is coated and filled, and then dried and chemically formed using a known method to form negative and anode plates, respectively. The pole group is formed by sandwiching a separator such as a nylon fiber non-woven fabric between the negative and anode plates and winding them up in a spiral shape. The anode plate and the anode plate are shifted in advance so that the anode plate sticks out, and the anode plate is rolled up in the same way as before, and the current collecting metal piece 4 is welded as shown in Fig. 2 in the same way as in the conventional method. The battery can be assembled in exactly the same manner as the conventional method, and the battery performance is actually slightly better than that of the conventional method.
