ABSTRACT:
A negative electrode for lead-acid storage batteries comprises a grid plate (11) serving as the carrier for the active material and for current supply and return. The grid plate (11) is a network of plastic threads produced by a weaving process which is rendered electrically conductive by coating it, with a highly conductive thin layer of metal and additionally metallized with at least one coating of a lead-tin alloy or of lead. The grid plate (11) is subdivided into storage zones (12) produced by deep-drawing for receiving the active material and into current conducting zones (14) for current supply and return.
