Reduced graphene oxide nanosheet modified NiMn-LDH nanoflake arrays for high-performance supercapacitors

Abstract

Reduced graphene oxide (rGO) nanosheets are exploited as a modification layer on a Ni foam-supported NiMn-LDH nanoflake array electrode via a facile dip-coating method. rGO serves as a second electron collector, which promotes rapid charge transport and improves electrochemical reaction kinetics. Asymmetric supercapacitors are also assembled exhibiting excellent electrochemical performance.
