Abstract

PURPOSE:To lengthen the Japanese-Industrial-Standard-prescribed life of deep charging and discharge, by filling a Pb-Ca alloy base with a paste obtained by mixing diluted sulfuric acid, water and a powder of lead manufactured from a Pb-As alloy. CONSTITUTION:A paste obtained by mixing diluted sulfuric acid, water and a powder of lead manufactured from a Pb-As alloy by a ball mill process or a Burton-Pott process is filled in a Pb-Ca alloy base to manufacture a positive electrode plate. Since alpha-PbO2 which is relatively inactive electrochemically is produced because of the presence of As, it is hard for a discharge reaction to advance, and the fall in the degree of electric contact with an active material is suppressed. This results in lengthening the Japanese-Industrial-Standard- prescribed life of deep charging and discharge.

Lead powder produced by the Le method or Barton Pot method is kneaded with water and dilute sulfuric acid to form a paste-like substance, which is filled into a lead alloy substrate, and then processed through an acid soaking process, aging process, and drying process to form a non-chemical form. Plate plates are manufactured.

Problems with conventional anode plates using paste: Because there is a large amount of PbOs, which is relatively active electrically and chemically, the discharge reaction progresses deeply, creating a PbBoa layer at the substrate-active material interface. . As a result, electrical contact between the base and the active material is impaired, making it difficult for the active material to be discharged. Because of this, pb-ca
In the case of lead-acid batteries that use a metal-containing base anode, there is a drawback that in the JIS standard life test, which involves deep charging and discharging, the capacity rapidly decreases due to deterioration of the anode plate.
