PURPOSE:To obtain a sintered substrate whose deterioration of mechanical strength and conductivity is prevented even if porosity is increased by mixing metal plated organic hollow balls to slurry containing nickel powder and spreading the mixture on the supporter, drying, then sintering them. CONSTITUTION:Metal plating such as nickel plating is applied on the surface of organic hollow balls such as acrylic resin having a particle size of 5-200mum. The hollow balls are mixed with nickel powder, and water and a binder are added to the mixture and they are stirred to prepare slurry. The slurry is spreaded on a perforated metal supporter, dried, then sintered to obtain a sintered substrate for an alkaline storage battery. By this method, contact between nickel particles and contact of nickel particle with the metal supporter are increased. Therefore, even if porosity of sintered substrate is increased, deterioration of mechanical strength or conductivity is suppressed. |
