Electrochemical storage cell, particularly of the alkali metal and sulfur type having at least one storage cell with insulation around the cell to minimize heat loss, and an interspace between the cell and the insulation. A heat exchanger in the form of a closed hollow body is partially filled with a vaporizable medium. The heat exchanger has two heat exchange zones in open communication. A first heat exchange zone is disposed in the interspace for preventing overheating of the cell by vaporization of the cell contained therein. The second heat exchange zone is disposed adjacent means for absorbing heat to condense vapors of medium which flow from the first heat exchange zone to the second heat exchange zone.

Electrochemical storage battery of alkali metal and sulfur with at least one storage cell, insulation around the cell, to minimize loss of heat from the cell, an interspace between the cell and the insulation, a heat exchanger in the form of a closed hollow body partially filled with a vaporizable medium, said heat exchanger having at least two heat exchange zones in open communication, with a first heat exchange zone disposed in the interspace and embedded in a heat storage medium filled in the interspace for preventing overheating of the cell by vaporization of the medium contained therein, and a second heat exchange zone arranged in a heat storage medium, provided in a heat insulated container positioned beside the storage battery to condense vapors of medium which flow from the first heat exchange zone to the second heat exchange zone and also to return heat to the storage battery and prevent cooling during pauses in operation of the battery, and a heater for heating the second heat exchange zone if the temperature of the storage battery is too low, in which case the second zone is heated to effect heat transport from the second zone to the first zone.
