The present invention relates to a positive electrode plate for an alkaline storage battery, particularly a paste-type nickel plate, and an object of the present invention is to provide a high-performance, low-cost, and highly productive nickel positive electrode plate. Conventionally, as a nickel positive electrode plate for an alkaline storage battery, a sintered type electrode plate is well known, in which a porous substrate made by sintering nickel powder into a perforated steel plate or a nickel net is filled with an active material. This porous substrate is made by simply sintering nickel powder into a perforated steel plate or nickel net, and the bond between the nickel powder particles is weak and falling off occurs when the porosity is increased.
The limit is about 80%. In addition, since these porous substrates have weak bonds between nickel powder particles, they always require a core metal such as a perforated steel plate or nickel net, and have the disadvantage that the amount of active material filled per unit volume is reduced by the volume of the core metal. ing. Furthermore, since the pores of the porous material are as small as 10 μm or less,
The filling method is limited to the solution impregnation method, which involves repeated complicated steps. In an attempt to improve these drawbacks, for example, a solid active material is directly filled into a nickel-plated iron fiber sintered body, a nickel fiber sintered body, etc. without a core metal. A so-called paste filling method is used. Another type of electrode plate that is directly filled with a solid active material is a pocket type electrode plate, but this type has a structure in which a perforated steel plate is processed to create a pocket part and the active material is filled in the pocket part. The perforated steel plate occupies a large volume, and the packing density per unit area is quite low. Hitherto, inexpensive methods for manufacturing metal fibers include cutting methods and methods in which metal powder is processed and sintered into fibers. The cutting method uses a fixed bit shape with a wire diameter of several mm.
There are two types of cutting: one is cutting fibers by moving a metal wire, and the other is so-called chatter vibration cutting, which utilizes automatic vibration during cutting. Metal fibers can be manufactured with a diameter of about 4 μm, and the thinner the fiber diameter, the greater the surface area and the better the utilization of the active material. On the other hand, as the fiber diameter increases, the surface area decreases and the active material utilization rate definitely decreases, so fibers with a diameter of 50 μm or more have little merit. Considering the pore distribution, tensile strength, and active material utilization rate of a substrate that is easy to fill with active materials in practical use,
The thickness is preferably about 4 to 50 μm. A porous substrate is obtained by uniformly distributing the fibers using an air-laid method or other methods and then sintering them in a reducing atmosphere at a high temperature of about 1000°C. By controlling the amount of fiber, sintering temperature, time, etc., a porous substrate having a porosity of about 85 to 98% and satisfying practical strength can be obtained. Note that if this porous substrate is made of iron fiber, nickel plating of 10 to 20% is required to prevent corrosion in an alkaline electrolyte. Conventionally, when these porous substrates are filled with an active material containing nickel hydroxide as a main component, the active material utilization rate is lower than that of, for example, a sintered electrode plate. The present invention has been made to improve this point, and focuses on the fact that the active material utilization rate can be improved by applying cobalt plating to the porous substrate in advance. According to the present invention, first, a porous substrate is plated with cobalt of about 1 to 2 μm, and the cobalt-plated porous substrate is coated with nickel hydroxide as a main component and a small amount of cadmium hydroxide or cobalt hydroxide. The active material contained in a crystalline state is filled in a slurry form with a solvent such as water, and then dried.
Adjust the thickness and use it as a positive electrode plate. An embodiment of the present invention will be described in detail below. After distributing the nickel fiber obtained by the chatter vibration cutting method using the air lading method, it was sintered at 1050°C for about 30 minutes in a reducing atmosphere to a thickness of 2 mm and porosity.
A 95% porous substrate was obtained. After that, it is heated in a plating bath consisting of cobalt ammonium sulfate, ammonium acetate, acetic acid, formalin, cadmium sulfate, etc.
~2 μm cobalt plating was applied. To this cobalt-plated porous body, about 10% by weight of nickel powder is added to a eutectic material consisting of 94% by mole of nickel hydroxide, 5% by mole of cobalt hydroxide, and 1% by mole of cadmium hydroxide, and then mixed well. A slurry made by adding about 40% by weight of water and about 2% by weight of carboxymethyl cellulose was filled, dried, and the thickness was adjusted to obtain a positive electrode plate of 0.7 mm. The packing density of the active material is approximately 1.8 g/cc.
This positive electrode plate was cut into 4 x 4 cm pieces, charged and discharged in a potassium hydroxide electrolyte, and the energy density (mAh/
cc) was measured. For comparison, the energy density (mAh/cc) of a positive electrode plate with the same dimensions but not plated with cobalt was determined. Table 1 shows the results in potassium hydroxide electrolyte with a specific gravity of 1.24.
After filling for 15 hours with 0.1C current, 0V with 0.2℃ current
A comparison of energy density (mAh/cc) when discharged to (VS.Hg/HgO) is shown.

Next, iron fibers with a fiber diameter of 20 to 30 μm and a length of about 50 mm obtained by a shaving method in which an iron wire with a wire diameter of several millimeters is moved onto a fixed cutting tool and cut are uniformly distributed using an air lading method. , under hydrogen atmosphere
Sintered at 900℃ for 30 minutes, thickness 2mm, basis weight approx.
A porous body of 500 g/m 2 was prepared and nickel plated to a thickness of approximately 3 μm in a nickel sulfate plating bath.
The fiber diameter is 20mm by the chatter cutting method of iron ingots.
Porous iron fibers with a length of ~40 μm and approximately 30 mm are made in the same manner as nickel plating, or nickel powder or nickel oxide powder is mixed with an organic binder such as carboxymethylcellulose to form a slurry, and a large number of thin, approximately 50 μm long iron fibers are prepared. After extruding it from a nozzle to form a non-woven fabric,
℃, in a high-temperature reduction furnace under a hydrogen atmosphere to form a nickel fiber porous body (high-temperature reduction method). A positive electrode plate plated with cobalt and a positive electrode plate not plated with cobalt were prepared, and the energy density of the positive electrode plates was measured.
The results are shown in FIG. As is clear from FIG. 1, no matter what type of fibrous porous material is used, the active material utilization rate can be improved by plating with cobalt. From this, it is presumed that the contact surface between the fibrous porous material and the active material plays an important role in improving the active material utilization rate. In other words, cobalt changes from Co→ in the anode direction in the alkaline electrolyte.
Since it has the property of dissolving once as HCoO 2 →Co 2 O 3 and precipitating, it is presumed that the active material utilization rate is improved because it has the effect of completely connecting the current collector surface and the active material. The metal fiber positive electrode plate of the present invention has an energy density that is approximately 40% higher than that of a conventional nickel powder sintered electrode plate. The reason for this is that high-density packing of the active material is now possible due to no need for a metal core and the use of a highly porous substrate, and a higher active material utilization rate than conventional metal fiber positive electrode plates can be achieved. This is because the. In today's world where batteries are required to be more compact, the present invention makes it possible to manufacture a nickel positive electrode plate with high energy density and at low cost, and its industrial value is extremely great.
