Date Jul. 23, 1981.In a one-cell or multi-cell lead salt electric storage battery with electrodes of first order, the anode of the cell or each cell has an active anode body (4) consisting of graphite fibers in textile structure. This active anode body is connected with an electrolyte-impervious, electrically conductive cell closure (1) consisting of moulded artificial resin with moulded-in, uniformly distributed short graphite fibers. The connection between the active anode body and the cell closure is established either by gluing with an artificial resin glue (5) with mixed-in short graphite fibers, or by embedding fibers at the surface of the active anode body in the artificial resin of the cell closure (1) by temporary softening of the surface of the artificial resin by heat or by the application of a volatile solvent. The electrolyte consists of lead silicofluoride (PbSiF6) with or without addition of lead methane sulfonate (Pb(CH3SO3)2) dissolved in water. The graphite fibers used for the anode body and the artificial resins with admixed short graphite fibers are such as are capable of withstanding a gas development test specified in the description. Important examples are pitch-based graphite fibers having a solid matter density above 1.8 g/cm3. The cell or each cell of the battery may be permanently hermetically closed because no gas is developed within the battery at any time. |
