PURPOSE:To improve the sudden discharge characteristics of a paste type positive electrode at low temperatures by adjusting lead paste while containing a specified range of aluminosilicate soda for a lead powder compound and applying it to the support body of the positive electrode. CONSTITUTION:Aluminosilicate soda is mixed in a lead powder compound at a rate of 0.2-4wt% and is kneaded by adding water and the lead paste is adjusted by continuing kneading while adding dilute acid. In addition, a grid body made of a lead alloy is filled with it and a paste type positive electrode plate is formed by aging and drying. Thus, since aluminosilicate soda is porous and has an excellent property in the adsorption of positive electrode ions, it effectively actuates the move of a dilute ion and a lead ion at the charge and discharge of the negative electrode. As a result, the sudden discharge characteristics of the lead acid storage battery using this positive electrode can sharply be improved at low temperatures. |
