ABSTRACT:
An improved reversible electric cell of the type which includes a soluble metal cathode, a chemically nonreactive electrode and an electrolyte comprising an aqueous solution of a metal halide is disclosed. The electrode is provided with open channels or grooves in which a dispersion, of paste-like consistency, is disposed. The dispersion or mixture comprises an inert conducting powder and an alkylammonium perchlorate. The alkylammonium perchlorate combines with the halogen released upon charging to form an addition product in a solid state. This prevents the halogen from being dissolved in the electrolyte during the charging cycle which would corrode soluble metal cathode and discharge the cell.
