<P>PROBLEM TO BE SOLVED: To provide an electrode for a lead battery by preventing a short circuit between electrodes from occurring upon a chemical treatment in a battery jar, where the chemical treatment in the battery jar makes an untreated electrode into the electrode for lead battery, the lead battery meets requirements of a lead battery for automotive use and industrial use, and the requirements are effective discharge performance, miniaturization, weight reduction, sealed packaging, and prolongation of a service life. <P>SOLUTION: The untreated electrode is manufactured through a step for charging an active material into a substrate, a step for pre-drying the substrate charged of the active material, a step for ripening the substrate, and a step for drying the substrate, where the electrode for lead battery is manufactured by chemical-treating the untreated electrode charged of the active material with dilute sulfuric acid after the ripening step for manufacturing the untreated electrode. <P>COPYRIGHT: (C)2004,JPO |
