PURPOSE:To uniformly distribute an adequate amount of electrolyte in plates and retainers by pouring a sulfuric acid containing gel mainly comprising silica into retainers, and performing formation in a container with step constant current. CONSTITUTION:Conventional production and assembly processes are omitted, and non-formed plates are assembled and put into a container. An adequate amount of dilute sulfuric acid is impregnated into plates and retainers, then, a sulfuric acid containing gel mainly comprising silica is poured into the retainers. Formation is performed in the container with step constant current, and controlled in the potential at which closed reaction is undergone in the final stage of the formation. thereby, the electrolyte is uniformly distributed into the plates, and in addition the process is simplified. |
