Lightweight plastic grids for lead/acid battery plates have been prepared from acrylonitrile butadiene styrene copolymer. The grids have been coated with a conductive and corrosion-resistant tin oxide layer by a novel rapid thermally activated chemical reaction process. X-ray powder diffraction and X-ray photoelectron spectroscopy show the coated tin oxide film to be $SnO_2$-like. The grids are about 75% lighter than conventional lead/acid battery grids. A 6 V/1 Ah lead/acid battery has been assembled and characterized employing positive and negative plates made from these grids. The energy density of such a lead/acid battery is believed to be more than 50 Wh/kg.
