NOVELTY - An electrode (E1) for an electrochemical generator comprises: a solvent having metal ions and oxygen dissolved in it, where the metal ions are alkali metal ions, alkali earth metal ions, or lanthanide metal ions; a fluorinated or metalloprotein oxygen dissolution enhancer provided in the solvent for enhancing dissolution of oxygen in the solvent; a metal oxide dissolution enhancer provided in the solvent for enhancing dissolution of metal oxide formed via reaction of oxygen with metal ions in the solvent; and a current collector provided in electrical contact with solvent.    USE - As an electrode for an electrochemical generator for generating an electric current (claimed), as a positive electrode useful for e.g. lithium batteries, primary and secondary electrochemical cells, electrolysis devices, flow cells, and fuel cells, for high performance portable electronic devices and hybrid electric vehicles.    ADVANTAGE - The oxygen and metal oxide dissolution enhancers in the electrode enable an increased oxidation and/or reduction rate, and enhance the stability and efficiency of the electrochemical generators. The electrodes comprise readily available and inexpensive material, and are highly versatile and compatible with a wide range of solid state and liquid anode and electrolyte systems.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) an electrochemical generator (G1) comprising: the positive electrode (E1); a negative electrode comprising an active negative electrode material; and a separator provided between the negative electrode and the positive electrode, where the separator conducts metal ions as a charge carrier;    (2) generating an electrical current involving: providing the electrochemical generator comprising a positive electrode comprising: a first solvent having metal ions and oxygen dissolved in it; a fluorinated or metalloprotein oxygen dissolution enhancer provided in the first solvent; a metal oxide dissolution enhancer provided in the first solvent; a current collector provided in electrical contact with the first solvent; a negative soluble electrode comprising: an electron donor comprising an electron donor metal provided in a second solvent, where the electron donor metal is an alkali metal, an alkali earth metal, a lanthanide metal or their alloy; an electron acceptor provided in the second solvent, where the electron acceptor is a polycyclic aromatic hydrocarbon or an organic radical; a supporting electrolyte comprising a metal at least partially dissolved in the second solvent; a current collector provided in contact with the second solvent; where at least a portion of the electron donor comprising an electron donor metal is dissolved in the second solvent, thereby generating electron donor metal ions and solvated electrons in the second solvent; a separator provided between the negative soluble electrode and the positive electrode, where the separator is non-liquid and conducts the electron donor metal ions as a charge carrier in the electrochemical generator; and discharging the electrochemical generator;    (3) charging (M1) the electrochemical generator involving: providing the electrochemical generator (G1); selecting a charging voltage and/or current for charging the electrochemical generator; and providing the selected voltage and/or current to the electrodes of the electrochemical generator to charge the electrochemical generator; and    (4) discharging and refueling the electrochemical generator involving: providing the electrochemical generator (G1); discharging the electrochemical generator, thereby generating a discharged electrochemical generator; removing all of the electron donor metal, electron acceptor and second solvent from the soluble negative electrode from the discharged electrochemical generator; providing electron donor metal, electron acceptor and second solvent to the soluble negative electrode to the discharged electrochemical generator; removing all of the first solvent, fluorinated or metalloprotein oxygen dissolution enhancer, and metal oxide dissolution enhancer from the positive electrode from the discharged electrochemical generator; and providing first solvent, fluorinated or metalloprotein oxygen dissolution enhancer, and metal oxide dissolution enhancer to the positive electrode to the discharged electrochemical generator; thereby refueling the electrochemical generator.
