PURPOSE:To enhance the utilization rate of an active material by packing a supporting body with both the active material and a powder, which is obtained by making a core powder in contact with a dispersion prepared by dispersing silicone into a disperse midium before the mixture is dried and crushed. CONSTITUTION:As an original solution, a cold-vulcanized silicone rubber emulsion containing a stabilized silicone rubber is prepared by using one kind of liquid. Next, the original solution is diluted with water,and a carbon powder obtained by carrying out 100-200 mesh sieving is kneaded into the diluted original solution. Next, the carbon powder moistened with the solution by stiring is dropped onto a high-speed rotary disk, and the carbon powder cores are dried while being separted. After that, thus obtained carbon powder is added to a paste prepared by kneading lead powder, sulfuric acid and water together, and the mixture paste is applied to a lead alloy grid before the grid coated with the mixture paste is dried, thereby making a pasted electrode. As a result, the diffusion path of electrolyte into the electrode body is secured due to the porous elastic particles excisting in the porous matter. Consequently, the utilization rate of the active material can be increased. |
