ABSTRACT:
In an electric storage battery having plate electrodes, the capacity and useful life is improved through uniform distribution of concentration and temperature of the electrolyte by means of electrolyte circulation. A synthetic plastic plate positioned between the plate electrodes and the housing wall of the storage battery contains a plurality of vertically extending transport tubes which are open at their upper and lower ends. The bottom portions of the transport tubes, which are immersed in the electrolyte, are connected to compressed air ducts. The compressed air is mixed with the electrolyte present in the transport tube in such a manner that the electrolyte-air mixture present therein is lifted, due to its lower specific gravity, by the electrolyte which surrounds the transport tube. The electrolyte leaving the transport tube produces continuous circulation within the storage battery, and this ensures permanent exchange of the electrolyte present between the plate electrodes.
