ELECTROCHEMICAL STORAGE BATTERIES AND MODULES THEREFOR

摘要

A battery module for a sodium sulphur battery containing a plurality of cells comprises a container housing the cells with an evacuated region between the cells and the walls of the container, this evacuated region containing a plurality of layers of metal foil between the cells and the wall. At least one tube extends through the module in contact with the cells for conveying a thermally-conductive fluid by means of which the cells can be heated or cooled.
