PURPOSE:To improve the property of active material for higher utilization factor by using the active material containing lead acid barium. CONSTITUTION:Dilute sulfuric acid is being gradually added to lead powder and kneaded therewith to form paste. To the paste, lead acid barium which has acid proof, oxidation resistance and high conductivity and still out of which harmful impurities to a battery are not solved is added and kneaded again. As conductive additive is formed of lead and barium in this way, if it is solved into electrolyte there is no harmful effect to the battery. It is thus possible to enhance the conductivity of active material and improve the utilization factor. |
