Three dimensional iron oxide/graphene aerogel hybrids as all-solid-state flexible supercapacitor electrodes

Abstract

Three dimensional iron oxide/graphene aerogel hybrid (Fe₂O₃/GA) was synthesized and used as electrode materials in flexible supercapacitor devices, which show high specific capacitance of 440 F g⁻¹ with 89% capacitance retention after 2200 cycles.
