ABSTRACT:
A sulfur/aluminum battery in which an aluminum anode and an aqueous alkaline/polysulfide electrolytic solution are in direct contact. At high polysulfide concentrations, parasitic chemical reactions between the aluminum and sulfur are minimized, allowing for efficient oxidation of the aluminum anode, and resulting in a battery having high energy and power densities.
