PURPOSE:To provide an electrode plate having high chemical converting efficiency without using sulfate by kneading a specific mixture in a specific compound, forming a paste-like active material while feeding water, to be applied to a lead grid member, followed by aging and drying, and obtaining a cathode plate. CONSTITUTION:A mixture of particulate silica and tribasic lead sulfate added into minium is kneaded. The resultant mixture is further kneaded while feeding water, thus obtaining a paste-like active material. The obtained active material is applied to a lead grid member, followed by aging and drying, thereby obtaining a cathode plate. It is possible to provide an electrode plate for a lead-acid battery having high chemical converting efficiency without taking specific corrosion measures by a method using kneading liquid not including sulfate. |
