FIG. ( 1 ) shows a battery generally designated ( 1 ), which is a lead-acid battery. The battery ( 1 ) includes the components normally found in a GMF (glass microfibre) battery. The battery ( 1 ) includes a container or box ( 2 ) of tough flame retardant material and positive plates or electrodes ( 3 ) comprising lead alloy grids covered with an active material of lead dioxide. In one embodiment of the battery ( 1 ), acid gelling material such as silica or the like (for example fumed silica or sodium silicate) is introduced into each GMF separator ( 5 ), preferably, during the manufacture of the separator itself. In a second embodiment, a gel is made up outside the separator container, for example, by mixing sodium silicate solution (water glass) and sulphuric acid and the battery is filled with the gel, thus allowing a gel to develop generally uniformly throughout the container and battery. |
