Abstract

Provided are a battery electrode plate, a manufacturing method for the same, an electrode plate group having said electrode plate, and a lead-acid battery. The electrode plate is equipped with a collector and an active material layer supported on the collector. The collector is an expanded grid manufactured by an expansion method. The electrode plate comprises two projection ends, each having a projection, and a planar intermediate portion disposed between the two projection ends. The ends are thicker than the intermediate portion, and if the thickness of the intermediate portion is taken as H2, and the difference between the thickness of the ends and thickness of the intermediate portion is taken a s HI, H1/H2, the ratio of HI to H2, is 3-9%. In the present invention, the electrode plate i s designed so that the ends thereof form projections, and the projection ends have projections, and the ends of the electrode plate are thicker than the other part of the electrode plate, whereby moderately increasing the pitch between the positive electrode plate and the negative electrode plate results in a significant improvement in the cycle life, capacity and discharge efficiency of a battery.
