- Abstract
- CoMn2O4 nanoparticles supported on N-doped reduced graphene oxide (CoMn2O4/N-rGO), for rechargeable zinc-air battery were prepared by a hydrothermal method. The CoMn2O 4 supported on nitrogen-doped graphene oxide showed better oxygen electrode potential compared with CoMn2O4 dispersed on graphene oxide. The zinc-air battery can be reversibly charged/discharged for hundred cycles with a good cycle performance. The improved battery performance of CoMn2O4/N-rGO can be attributed to the synergistic effect of covalently coupling between the nitrogen-doped graphene sheets and spinel cobalt manganese oxide. © 2014 Elsevier B.V.
