<p><P>PROBLEM TO BE SOLVED: To provide a control-valve type lead-acid storage battery with a long life in which a paste type negative electrode plate and a paste type positive electrode plate are used. <P>SOLUTION: Into dilute sulfuric acid and aliquots of water, barium sulfate powders, lignin powders, and cut fibers which are surface-treated by silica and alumina of the average particle diameter of≤0.03μm are added and kneaded so that a slurry is prepared beforehand, and lead powders are added to the slurry and kneaded so that a paste-formed active material for the negative electrode is prepared. The prepared paste-formed active material for the negative electrode is made to be filled into a current collector made of a lead alloy, aged/dried, and the paste type negative electrode is manufactured and used for manufacturing the control-valve type lead-acid storage battery. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
