  • High-temperature storage battery
    Patent number: 5158841
    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.
