摘要：

Lightweight grids for lead-acid battery plates are prepared from flexible graphite sheets of mass density 1.1 g cm(-3). The grids are coated with a lead layer followed by a corrosion-resistant polyaniline layer by electrodeposition. The grids are about 70% lighter than conventional lead-acid battery grids. The suitability of these grids are evaluated by cyclic voltammetric experiments. Lead-acid cells are assembled with positive and negative plates made from these lightweight grids. The specific energy of the lead-acid cells is found to be ca. 40 Wh kg(-1) at the C/5 rate. (C) 2007 Elsevier B.V. All rights reserved.
