A lead battery or accumulator in which each electrode is wrapped in a web of say, fiber glass, the electrolyte consists of a mixture of sulphuric acid and phosphoric acid, and the electrolyte is made thixotropic by addition of a jell-forming material, such as silicon dioxide with a particle size of 0.01 to 0.02 microns. The web provides pockets which hold the electrolyte, and between adjacent electrodes there are disposed perforated, undulant spacers. The electrode grids are preferably made of a lead-calcium base. Preferably the electrodes are charged while dry, then wrapped in the fiber web, then assembled into the battery housing; then the electrolyte is introduced into the housing; and the housing is ventilated. |
