Abstract: A high-temperature storage battery is bounded by a thermal insulation and has an inner space in which electrically interconnected storage cells are disposed and secured. The storage cells are secured in such a way that an adequate cooling and heating of the storage cells is made possible. In order to form a storage cell block, the storage cells are embedded in a sealing compound or a course-grained loose material. Cooling devices are integrated in the storage cell block or disposed on the outside directly adjacent the block for conducting heat to the block. Heating elements are provided for heating up the storage cells.

Abstract: In order to uniformly distribute a coolant, e.g. air, over gaps between electrochemical cells in high-temperature storage batteries, it has already been proposed to place an open chamber above the groups of cells from which the coolant is preferably conveyed to the cells through holes in a distributor panel. The object of the invention is to even further improve the distribution of the coolant. In order to achieve a uniform, quasi-flat incident flow profile for the coolant over the distributor panel, an antechamber is provided for receiving the coolant from at least one inlet opening and for passing the coolant through several throttle locations into an open chamber and then through holes in the distributor panel to the cells. The invention can be applied to sodium/sulphur batteries, for example.
