Abstract
An electrical storage battery consisting of one or a plurality of cells, each comprised of a normally positive electrode for reducing a halogen disposed in electrical contact therewith and a normally negative electrode having an oxidizable metal disposed in electrical contact therewith during an electrical discharge of the cell. The cell is filled with an aqueous metal halide electrolyte which is adapted to be circulated between the cell and a storage area containing a replenishable halogen hydrate which is progressively consumed during discharge of the battery. A replenishment of the oxidizable metal is also effected periodically accompanied by a withdrawal of a controlled portion of the electrolyte to maintain the volume thereof within a preselected range.
