Method of making a battery
A method of making a battery includes forming a strip of interconnected grids from a grid material by feeding a continuous strip of the grid material along a linear path aligned with the longitudinal direction of the strip and punching grid material out of the strip. Each interconnected grid includes a plurality of wires, with each wire having opposed ends joined to one of a plurality of nodes to define a plurality of open spaces. The method also includes modifying at least one of the wires at a position intermediate the opposed ends of the wire such that a first transverse cross-section taken intermediate the opposed ends of the wire differs from a second transverse cross-section of the wire taken at one of the opposed ends of the wire. The method further includes applying paste to the strip and cutting the strip to form a plurality of plates.
