る。Conventional Structure and Problems The band-shaped electrode plate of a cylindrical alkaline storage battery is formed by a conventional method. That is, a band-shaped porous core material 3 is prepared as shown in FIG. 1, which is a perforated steel plate plated with nickel and having a perforated portion 1 for the most part and non-perforated portions 2 for both left and right edges. In the case of a nickel positive electrode, carbonyl nickel powder is sintered into the perforated part of this core material to form a nickel sintered substrate to hold the active material, and in the case of a cadmium negative electrode, as shown in Figure 2. It is formed by continuously applying and drying a paste-like active material 4 and cutting it into a predetermined electrode plate width.

て所定幅、所定長さの極板とする。Taking a cadmium negative electrode plate as an example, the conventional method for producing the plate is to produce one continuous strip-shaped electrode plate as shown in Figure 5.
First, cut the unit electrode plate 5 into strips with a predetermined width, and then cut off the core material non-porous portions 2 on both the left and right sides of the plate with a cutter 1"@6 to obtain an electrode plate with a predetermined width and length. .

After spot welding 7, an e-edge tape 8 for guaranteeing was pasted on the surface of the spot weld as shown in r) to complete the unit electrode plate 5a.

のである。However, with such electrode plates, the cutting process to complete the unit electrode plate 5a includes cutting, scraping off the active material, and welding processes, which requires a large number of processing steps and also causes a large amount of material loss. Furthermore, if the spot welding of the lead plate is incomplete, the current collection efficiency decreases, making it difficult to fully demonstrate the electrode plate performance.Objective of the InventionThe present invention solves these conventional problems. Solved, cutting the non-porous part of the core material extending outward from both left and right ends of the strip-shaped plate,
The 'J-to part protruding diagonally in the -E direction is formed integrally with the core material, and the reed part can be obtained with good workability.
Structure of the Invention The present invention aims to ensure welding to the inner surface of the battery case.In order to achieve the above object, the present invention provides a non-porous portion of the core material extending outward from both left and right ends of the electrode plate. It is characterized by having a substantially arrow-like lead part integrally formed with the core material, which is cut at the same time as the electrode plate of a predetermined size is cut, preferably from the dog-sized electrode plate, and projects diagonally upward. The present invention provides a sealed alkaline storage battery that is easy to process, has excellent current collection efficiency, and has good performance.

are processed in advance, and the non-porous portions 2 of the core material extending outward from both left and right ends of the electrode plate are cut as a substantially arrow-like lead portion 10 projecting diagonally upward as shown in FIG. 4. .

芯材無孔部２の切断に伴う材料ロスは生じない。The approximately arrow feather-shaped lead portion 1o is formed by forming a portion on the side of the unit electrode plate that will be cut later (upper side in the figure) when cutting the unit electrode plate 5a from the band-shaped electrode plate shown in FIG. It is best to cut the core material by shifting the position of the non-porous part 2 so that it is biased.
No material loss occurs due to cutting of the non-porous core portion 2.

正極板に本％明を適用することもてきる。In such a band-shaped venerable electrode plate according to the present invention, approximately feather-shaped glue portions are provided integrally with the core material at both left and right ends over the entire width of the electrode plate, and the active proboscis is formed as in the case of the ox. There is no need to scrape off the lead plate or spot weld a separately prepared lead plate, and the current collection efficiency from the electrode plate is extremely good, so the excellent electrode plate performance can be fully demonstrated. Furthermore, when welding to the inner surface of the battery case, the leat part does not peel off at all, and a leat part that is easy to weld can be obtained with no loss of material and with good workability. Of course, the present invention can be applied not only to cadmium negative electrode plates but also to 21.7 Kel positive electrode plates.
