LEAD/SULPHURIC ACID STORAGE BATTERY

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 uncrosslinked 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.
