Graphene help researchers to develop efficient oxygen catalysts for lithium-oxygen batteries

Researchers from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) and Henan Agricultural University have designed two-dimensional (2D) Mn3O4 nanosheets with dominant crystal planes on graphene (Mn3O4 NS/G) as efficient oxygen catalysts for Li-O2 batteries, achieving ultrahigh capacity and long-term stability.
