However, the parasitic reactions involving the discharge product of NaO\n            <jats:sub>2<\/jats:sub>\n            or K anode with electrolytes and the severe Na or K dendrites plague their rechargeability and cycle stability. Herein, we report a hybrid Na\/\/K\n            <jats:sup>+<\/jats:sup>\n            -containing electrolyte\/\/O\n            <jats:sub>2<\/jats:sub>\n            battery consisting of a Na anode, 1.0 M of potassium triflate in diglyme, and a porous carbon cathode. Upon discharging, KO\n            <jats:sub>2<\/jats:sub>\n            is preferentially produced via oxygen reduction in the cathode with Na\n            <jats:sup>+<\/jats:sup>\n            stripped from the Na anode, and reversely, the KO\n            <jats:sub>2<\/jats:sub>\n            is electrochemically decomposed with Na\n            <jats:sup>+<\/jats:sup>\n            plated back onto the anode. The new reaction pathway can circumvent the parasitic reactions involving instable NaO\n            <jats:sub>2<\/jats:sub>\n            and active K anode, and alternatively, the good stability and conductivity of KO\n            <jats:sub>2<\/jats:sub>\n            and stable Na stripping\/plating in the presence of K\n            <jats:sup>+<\/jats:sup>\n            enable the hybrid battery to exhibit an average discharge\/charge voltage gap of 0.15 V, high Coulombic efficiency of &gt;96%, and superior cycling stability of 120 cycles.
