The “nonsticky” surface of a highly stable RuO 2 /carbon nanotube cathode enhances the formation and decomposition of cathode surface‐induced, solvation‐mediated, micrometer‐sized discharge products Li 2 O 2 in Li–O 2 batteries and thus significantly improves the specific capacity, overpotentials, and cycle life. These findings contribute to a new understanding how the cathode surface controls Li–O 2 electrochemistry.
