ABSTRACT:
A grid has a grid structure (11) made of acid proof synthetic resin. A grid rib structure constitutes the grid structure and part of the grid rib structure inclusive of at least a connector lug (12) and a portion contiguous thereto is immersed in molten lead or lead alloy to form a lead or lead alloy film (16) coated on the grid structure. The portion to be coated with the lead or lead alloy film includes part of a frame rib (13) and an active material support rib (14, 15) which constitute the grid rib structure, and the active material support rib constituting the grid mesh is partly cut off (18) to enhance the coating of the lead or lead alloy film, the reduction in weight of the grid and ease of working for the coating of the lead or lead alloy film on the grid structure.
