Abstract
A grid for a battery plate is made by forming a metal sheet is formed into a grid-like shape. Rupture due to torsion or stress concentration does not occur in a basal portion of a wire which is drawn out from a node of the grid, thereby preventing corrosion due to electrolyte from advancing so as not to cause a crack of corrosion in an early stage. The invention provides also a battery using the grid for a battery plate, a method of producing the grid for a battery plate, and a battery using it.
