Abstract

PURPOSE:To increase the retainability of an active material, and strengthen the adhesion of a grid thereto by forming a groove on the side of a grid rib. CONSTITUTION:Each grid rib 2 of lead or lead alloy is cast to such a form as projecting in a thicknesswise direction. In this case, a lead-acid battery grid body 1 with a groove 3 on the side of the grid rib 2 can be easily manufactured, in accordance with a process where the groove 3 is formed on the side of the rib 2 by bending each projected section 2a of the rib 2. Also, the grid body 1 is charged with paste, and this paste is formed into an active material. According to this construction, the active material is enhanced in terms of retainability, and the adhesion of a grid thereto is also enhanced. Thus, the number of grids can be reduced to realize light weight, and the separation or a drop of the active material from the grid body 1 can be prevented, thereby enabling a drop in battery lifetime to be prevented. At the same time, the charge and discharge characteristics of a battery can be enhanced.
