Abstract

An electrochemical cell includes a negative electrode comprising a first active metal, a positive electrode comprising a second active metal, and an electrolyte comprising salts of the two active metals, a salt of the cathodic metal and a salt of the anodic metal. In operation, the electrolyte composition varies such that in a charging mode the salt of the anodic salt decreases, while the salt of the cathodic salt increases, and in a discharging mode the salt of the anodic salt increases, while the salt of the cathodic salt decreases. 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 an intermittent renewable energy source.
