Abstract
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.
