<p>1,138,718. Water-activatable dry-charged lead-acid storage cells. GOULD-NATIONAL BATTERIES Inc. 26 Sept., 1967 [26 Sept., 1966], No. 43799/67. Heading H1B. Water-activatable lead-acid cells contain a polyelectrolyte complex of ionically bonded polycationic and polyanionic organic resins containing sulphuric acid in an amount sufficient to provide a sulphuric acid electrolyte upon the addition of water to the cell. The acid-containing complex may form the plate separators of the cell. The separators may comprise a sheet of the complex or a felt or porous, inert, organic resin impregnated with the complex. Direct contact between the complex and the plates may be avoided by porous ribs on the surface of the separator or by sheets of acid resistant material. Alternatively the acidcontaining complex may be in a separate chamber connected to the cell. In the examples the sulphuric acid is absorbed on a complex of poly (sodium styrenesulphonate) with poly- (vinylbenzyltrimethylammonium chloride). The vents of the cells or batteries are hermetically sealed before storage to prevent deterioration.</p> |
