(57) [Problem] To provide a lead-acid battery that maintains a high utilization rate of active material for a long period of time by using an electrode active material containing tin oxide fiber that is stable even when held for a long time under a charging potential. Aim. SOLUTION: Tin oxide is a basic component, silicon oxide, Filling a current collector with an electrode active material containing lead oxide containing tin oxide fibers containing at least one metal oxide selected from the group consisting of germanium oxide, aluminum oxide, zirconium oxide, titanium oxide, and hafnium oxide And a lead storage battery using the same. |
