ABSTRACT:
A lead/sulphuric acid storage battery with negative and positive electrode plates, between which plastics microporous separators or glass-fiber separators are arranged, comprises un-crosslinked natural or synthetic rubber to combat antimony poisoning in the battery. The rubber is preferably in the form of a layer comprising un-crosslinked natural or synthetic rubber or is incorporated into a carrier layer on the separators, on the side facing the negative electrode plate. Alternatively, the un-crosslinked natural or synthetic rubber can be incorporated into the separator sheet or into the negative electrode plate. The deposition of the rubber as a coating onto the inner walls of the battery box is also possible.
