<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a lead acid storage battery which is small in size and light in weight and has a long trickle charge lifetime. <P>SOLUTION: The lead acid storage battery is manufactured by laminating a non-formed paste type positive electrode plate and a non-formed paste type negative electrode plate through a separator, and filling a dilute sulfuric acid electrolytic solution, then forming a battery case. Here, graphite is added 0.5-1.5 mass% to the lead powder in the active material of the paste type positive electrode plate, and phosphoric acid is added 0.05-1.0 mass% to the dilute sulfuric acid electrolytic liquid to manufacture the lead acid storage battery. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
