The present invention relates to a method for manufacturing a paste-type nickel positive electrode, which is a positive electrode that supports a paste-like active material as a component, which allows easy attachment of current collecting ears, and has excellent current collecting performance.

されている。Typical alkaline storage batteries include those that use nickel as the positive electrode and cadmium, zinc, or hydrogen as the negative electrode. Such nickel positive electrodes for alkaline storage batteries are conventionally made by impregnating a substrate obtained by molding and sintering carbonyl nickel with a nickel salt water bath solution, and then converting the nickel salt into nickel hydroxide in an alkaline aqueous solution. It has been common to use sintered nickel positive electrodes manufactured by the manufacturer. but,
This nickel positive electrode was not economical because the manufacturing process of the sintered substrate, the impregnation and conversion process of the active material, etc. were extremely complicated. Therefore, as an alternative to this sintered nickel positive electrode, a paste type nickel positive electrode is available, which is obtained by directly filling a paste containing nickel hydroxide as a main component into a substrate with a three-dimensional structure, such as nickel fiber nonwoven fabric. Proposed.

Using the vibration cutting method to cut nickel ingots, the wire diameter is reduced to 10.
This short fj! It is obtained by processing the fibers into a solid iron cloth by a method such as dispersion, and then sintering them in a reducing atmosphere. When the nickel fiber nonwoven fabric obtained by such a method is used as a substrate for a nickel positive electrode, the porosity is 90 to 9.
Since it is large (5 pieces), a large amount of nickel hydroxide, which is an active material, can be filled, and a large-capacity nickel positive electrode can be obtained. However, since such a substrate does not have a metal core like a punched metal in a sintered type, it is very difficult to attach a current collecting lug for an electrode, which is necessary when used as an electrode. Conventional mounting methods include, for example, removing the pasty active material that has adhered to the mounting area9, or applying strong pressure to the area before filling to make it thinner; In some cases, sufficient effects were not obtained.

We got the idea that it could be attached to the board by spot welding, and welded the current collector ears for the electrodes directly to the metal plate, and recognized that a similar effect could be obtained when actually used, and developed the present invention. I was able to complete it.

A metal plate made of a thin nickel plate or nickel-plated steel plate is placed and attached by spot welding at appropriate intervals, then filled with a paste-like active material, dried, and rolled in a direction parallel to the long length. After applying pressure with a press and cutting the metal plate, a current collector lug for the electrode is welded to the metal plate to form a nickel positive electrode, and the process from the roll-shaped sintered substrate to cutting is performed in a continuous process. be.

に該金属板を長尺方向と直角方向に基板と点溶接する。An example of the method for manufacturing a paste-type nickel positive electrode of the present invention will be described. First, as a substrate, short nickel fibers are made by cutting a nickel ingot into a wire diameter of several 10 to 100 μm using the chatter vibration cutting method, which is processed into a nonwoven fabric by a method such as dispersion, and then sintered in a reducing atmosphere. It is pressed to a thickness. The metal plate made of nickel plate or nickel-plated steel plate to be welded to this

隔は、電極の巾寸法またはその２倍とする。The reason why spot welding was used was that the electrode current collecting lug was welded to a metal plate that did not sandwich the electrode and had plain surfaces on both the front and back. The interval between welding points is preferably 10 to 20 times, depending on the shape of the welding machine. The spacing between the silver and metal plates shall be equal to or twice the width of the electrode.

る。On the substrate obtained by the above method, the uncoated portion of the attached metal plate and the current collecting lug for the electrode are superimposed, and a nickel positive electrode is obtained by spot welding. The nickel positive electrode of the present invention obtained in this manner has excellent charge and discharge characteristics because the current collecting tab for the electrode can be easily attached, and at the same time, the current collecting plate functions as a conduction path for electrons. It is possible to achieve this.

Nickel plates 2 having a width of 5iam, a length of 300im, and a thickness of 0.1mm are applied perpendicularly to the longitudinal direction at intervals of 40jtas on a rolled substrate 1 with a thickness of 1.5mm, and in step B
Spot welding 3 was performed at the blade spacing. This substrate is shown in FIG. Next, a paste-like active material containing nickel hydroxide as the main component is filled in step C, dried in step D, and then adjusted to a thickness of 0.7n with a roll press in step E, and then cut with a cutting machine in step F. It is cut to a size of width 40n and length 601mm, and a polarization collector tab 5 made of a nickel plate is welded onto the nickel plate 2 attached to the upper end of the nickel positive electrode 4. This is shown in FIG. This was wound together with a cadmium negative electrode and a separator, and an AA-sized storage battery was manufactured by inserting the can, injecting a KOH electrolyte, and sealing. The discharge capacity when this storage battery was charged at a current of O,]C for 15 hours and then discharged at various current values from 0.2C to 5C is shown by the solid line (A) in FIG. For comparison, a 4th nickel positive electrode a was prepared using a conventional method in which a paste-like active material was removed from a nickel nonwoven fabric as a substrate, and then a current collecting ear for the electrode was attached by welding.
The evaluation test similar to that of the AA size storage battery made using the nickel-free positive electrode 4 was carried out, and the results are as shown in the dashed line (b) in Fig. 5. The test results of the same battery with a bonded nickel positive electrode are also shown in the fifth column.
