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

進行し、基体−活物質界面にｐｂｓｏ、層を生成する。Function: In an anode plate using a conventional paste, since there is a large amount of α-PbO, which is relatively inactive electrochemically, the discharge reaction proceeds deeply and forms a PBSO layer at the substrate-active material interface.

この結果、基体と活物質との電気的な接触を損ない、活
物質が放電され難くなる。As a result, electrical contact between the base and the active material is impaired, making it difficult for the active material to be discharged.

触の低下が抑制される。In the anode plate according to the present invention, α-PbO, which is relatively inactive electrochemically, is generated due to the presence of Se.
Discharge reaction is difficult to proceed. Therefore, deterioration of electrical contact with the active material is suppressed.

ためであると考えられる。This difference in the activity of α-PbO is considered to be due to the presence of Se, which increases the 0/Pb ratio of pb(L), resulting in a stable form.
