Aluminum-Chlorine Battery

Abstract

Laboratory models of an aluminum-chlorine battery have been constructed and tested. The cells have an aluminum anode, a cathode consisting of chlorine stored on powdered graphite, and a molten aluminum chloride-sodium chloride electrolyte. The cells are normally operated as secondary cells, charging being accomplished by application of a reverse potential. Typical cells have an open circuit voltage of 2.55 volts, of which about 0.4 volt appears to be due to a concentration difference established in the electrolyte during electrical charging. With respect to the maximum current achievable, the conductivity of the melt seems to be the limiting factor.
