    摘要: An electric cell using aluminum in a negative electrode has a positive electrode (3, 4), the negative electrode (1) containing aluminium or aluminium alloy, and an electrolyte arranged between the positive electrode and the negative electrode. The electrolyte includes: at least one ion selected from a group of a sulfate ion (SO 4 2- ) and a nitrate ion (NO 3 - ); and an additive. The additive is selected from an organic acid, a salt of the organic acid, an hydrate of the organic acid, an ester of the organic acid, an ion of the organic acid, and derivatives thereof. Thus, the electric cell of the present invention using aluminum in a negative electrode allows the improvements in the voltage and the capacity of the cell as the generation of gas depending on the self-discharge can be prevented.

    摘要: 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.
