RECHARGEABLE BATTERY HAVING A WALL ELEMENT AND WALL ELEMENT THEREFOR

The invention relates to a rechargeable battery comprising a battery housing which has a cell cavity, or several cell cavities separated by dividing walls. One or more of the cell cavities have at least one respective positive and negative electrode, separated from each other by at least one separator, and a liquid electrolyte. One or more of the cell cavities have a respective wall element, which partitions the respective cell cavity into at least two volume chambers which communicate with one another. At least in the lower regions of the volume chambers, a communicating connection between the volume chambers for the liquid electrolytes is provided and in the upper region of the volume chambers, a pressure compensation connection between the volume chambers for assuring equal air pressure in the volume chambers communicating chambers is provided. Also disclosed is a wall element for such a rechargeable battery, and a battery housing.
