Lightweight grids for lead-acid battery grids have been prepared from acrylonitrile butadiene\udstyrene (ABS) copolymer followed by coating with lead. Subsequently, the grids have been electrochemically\udcoated with a conductive and corrosion-resistant layer of polyaniline. These grids are about\ud75% lighter than those employed in conventional lead-acid batteries. Commercial-grade 6V/3×5Ah (C20-rate)\udlead-acid batteries have been assembled and characterized employing positive and negative plates constituting\udthese grids. The specific energy of such a lead-acid battery is about 50 Wh/kg. The batteries can\udwithstand fast charge–discharge duty cycles.
