Superior radical polymer cathode material with a two-electron process redox reaction promoted by graphene

Abstract

Poly(2,2,6,6-tetramethyl-1-piperidinyloxy-4-yl methacrylate) (PTMA) displays a two–electron process redox reaction, high capacity of up to 222 mA h g−1, good rate performance and long cycle life, which is promoted by graphene as cathode material for lithium rechargeable batteries.
