摘要:
A conductive porous body that has a conductive layer almost free from impurities and that enables a metallic porous body having extremely low resistance to be produced with high productivity and production efficiency, and a metallic porous body and a battery plate both produced by using the conductive porous body. The conductive porous body has a nickel conductive layer formed on the surface of the framework of a plastic porous body having a continuous-pore structure. The conductive layer is formed by the deposition of nickel from an aqueous solution containing nickel compounds with the use of a reducing agent containing titanium compounds. The metallic porous body can be obtained by forming a continuous metal-plated layer on the surface of the framework of the conductive porous body. The metal-plated layer is formed by electroplating with the conductive porous body serving as the cathode. The battery plate consists mainly of the metallic porous body.
