Synergistic additives for electrochemical cells with electrodeposited fuel

Abstract

An embodiment of the invention provides for an electrochemical cell comprising: a fuel electrode comprising a metal fuel, a second electrode, an ionically conductive medium communicating the electrodes, the ionically conductive medium comprising at least two different additives, wherein at least one additive is selected from the group consisting of: macroheterocyclic compounds, phosphonium salts, hetero-ionic compounds and their derivatives; and, at least one additive is selected from the group consisting of: macroheterocyclic compounds, phosphonium salts, hetero-ionic compounds, and their derivatives. The fuel electrode and the second electrode are operable in a discharge mode wherein the metal fuel is oxidized at the fuel electrode functioning as an anode, whereby electrons are generated for conduction from the fuel electrode to the second electrode via a load. An ionically conductive medium and methods of operating an electrochemical cell are also disclosed.
