Zusammenfassung:	The invention relates to a kind of lead acid battery used in electric motor car. It consists of shell, slab lattice, active material and electrolyte. The weight percentage of alloy of positive pole slab lattice is as follows: Sb 0.1-2%, Cd 0.5-2.5%, Sn 0.03-0.5%, Al 0.005-0.1%. Lead being the rest. The invention makes improvement and adjustment on battery in sides of alloy formula of slab lattice, active material formula of positive pole, electrolyte, etc., thus prolonging service life of the battery. The invented battery provides service life more than double that in prior art and merits of lowering cost for using electric motor car, reducing times for replacing battery.
