Abstract
The object of the present invention is to improve the short-term discharge power after the thermal cycles, as the object of the improvement of the characteristics of the lead acid battery. An electrode for a lead acid battery comprising an electrode active material layer comprising a lead containing material, a porous carbon material and a binder, and a current collector, wherein when a weight of lead atom is A and a weight of porous carbon material is B, B/(A+B)×100 satisfies 1.0 to 90%; and said binder is a crystalline polymer having a melting temperature of 40° C. or less or amorphous polymer, is used.
