摘要： An electrochemical cell and its method of operation includes an electrolyte having a binary salt system of an alkali hydroxide and a second alkali salt. The anode, cathode, and electrolyte may be in the molten phase. The cell is operational for both storing electrical energy and as a source of electrical energy as part of an uninterruptible power system. The cell is particularly suited to store electrical energy produced by a renewable energy source. The positive electrode may comprise a metal selected from Cd, Sn, Hg, Pb, sb, Bi and any cobination thereof, the electrolyte may be a binary salt system comprising an hydroxideand a halide, and the negative electrode may comprise an alkli metal such as sodium (Na).
