望されているものであった。To hang a sintered substrate using this core, a slurry containing nickel powder is applied to the surface of the core, dried and then sintered, or nickel powder alone is coated on the core and then sintered. A nickel sintered body is provided by performing this process. However, this sintered substrate does not have sufficient adhesion between the nickel sintered body and the core, and when an alkaline battery is obtained by making electrodes with this sintered substrate, it is difficult to maintain the adhesion during use. However, if the sintered body and the core body were to separate from each other, there was a risk that the life of the alkaline battery would be prematurely shortened. Therefore, there is a need for a sintered substrate that has excellent adhesion between the sintered body and the core.

The adhesion to the nickel sintered body was tested for the perforated iron plate (comparative example core) that was used only with nickel plating. That is, a known nickel slurry consisting of an aqueous methylcellulose solution and nickel powder was applied to each of the core surfaces, dried, and then heated at 950°C in a reducing atmosphere.
After sintering for 10 minutes to form a sintered substrate with the sintered body in close contact with it, a tensile test jig was attached to the surface of each sintered substrate via an epoxy resin adhesive, and the core body was The peel strength of the sintered body in the vertical direction was measured. The results are shown in Table 1.

An accelerated life test was conducted. As a result, the alkaline battery using the comparative example core showed separation between the core and the sintered body after about 100 cycles and reached the end of its service life as an alkaline battery, but the alkaline battery using the core of Example (1) Even after 200 cycles, no peeling occurred between the core and the sintered body, and it was confirmed that the sintered body could withstand long-term use.
