One-step synthesis of Mn3O4/reduced graphene oxide nanocomposites for oxygen reduction in nonaqueous Li–O2 batteries†
Abstract
A Li–O2 battery based on the Mn3O4/RGO nanocomposite (monodispersed Mn3O4 nanoparticles supported on RGO) cathode exhibits excellent ORR activity and an outstanding initial discharge capacity as high as 16 000 mA h g−1.
