For the method of manufacturing an anode plate for use, the lead powder is covered with a film that is insoluble or difficult to dissolve in an acidic solution but is soluble in an alkaline solution and is substantially impermeable to sulfuric acid but permeable to water. Alternatively, the lead powder is covered with a coating which is insoluble or difficult to dissolve in sulfuric acid but soluble in lead hydroxide and substantially impermeable to sulfuric acid but permeable to water. Such a coating can be formed using, for example, a material whose main component is a mixture of a silicate and a silicofluoride salt. Magnesium silicate (Mg 2 SiO 4 ) or the like can be used as the silicate, and magnesium silicofluoride (Mg 2 SiF 6 ) or the like can be used as the silicofluoride salt.

Then, the water that has penetrated into the film reacts with the lead monoxide in the lead powder to produce lead hydroxide, and an alkaline solution is produced in the film. When the liquid in the coating becomes an alkaline solution, the coating dissolves and the lead monoxide is exposed.
At this stage, almost 100% of red lead has completed the reaction with sulfuric acid, and lead sulfate (PbSO 4 ) and lead dioxide (PbO 4
