| 摘要 |
A reduced weight lead-acid battery is produced incorporating light-weight negative battery plates each comprising an electrically-conductive open mesh grid formed from a strip of expanded, punched or cast metal, a pair of outer lower density support layers such as polymer or polymer-coated glass fibre or low density metal on each side of the central open grid, preferably arranged in a rectangular lattice, attached to each other through openings in the grid preferably by an acid-resistant adhesive, and an electrochemically-active paste saturating the void spaces thereof. An acid-resistant thermoplastic resin adhesive or ties or lugs may be used to attach the support layers together.
