An organic bifunctional catalyst poly(2,2,6,6‐tetramethylpiperidinyloxy‐4‐yl methacrylate) (PTMA) has been prepared and coated on carbon surface during electrode preparation. The PTMA has been applied as an efficient bifunctional catalyst for lithium–oxygen batteries with lower overpotentials, enhanced rate performances, and prolonged cycle life.
