PURPOSE:To obtain a maintenance-free battery with the excellent initial performance and life performance by using an alloy lattice made of specific amounts of individual nucleus chemical agents such as antimony, tin, aluminum, arsenic, and sulfur and a remaining amount of lead. CONSTITUTION:A lead storage battery is formed using an alloy lattice made of nucleus chemical agents including 2% or less, by weight, of antimony, 0.1% or more, by weight, of tin, 0.001-0.1%, by weight, of aluminum, a proper amount of arsenic, and an infinitesimal amount of sulfur, or selenium, or copper and a remaining amount of lead. Accordingly, the hydrogen over voltage of a cathode plate is prevented from being dropped, requiring to supply no water, thus a maintenance-free battery can be obtained, and the stability of Sb of the Pb-Sb melted alloy is improved due to the coexistence with Al, the work performance is improved, the terminal voltage for rapid discharge is improved due to the adition of Sn furthermore, the crystallinity of the alloy is made extremely fine due to the addition of the nucleus chemical agents, thereby the initial performance and life performance can be improved. |
