Low O 2 availability at the cathode in Li–air cells (A) is considered to be the major reason for their low practical capacity and power performance. Common organic electrolytes (blue) preclude the existence of a three‐phase gas/electrolyte/catalyst interface (B). Moreover, O 2 solubility is low in most organic electrolytes. To tackle these problems, an artificial three‐phase reaction zone (C) is created by implementing special oxygen carriers (perfluorocarbons, yellow) into the cathodic active sites.
