ABSTRACT:
A laminated alkaline battery grid has two thermoplastic outer gridwire network layers and a thermoplastic inner gridwise network layer sandwiched between the outer layers. A plurality of elongated intersecting welds extend as narrow channels in criss-cross fashion across the faces of the grid and bond the networks together. The channels are defined by walls formed by the fusion and exudation of the thermoplastic from the networks during welding and serve to divide the networks into a plurality of substantially symmetrical gridwire pockets. A metal coating on the gridwires and walls renders the thermoplastic grid conductive.
