Abstract

Nb₂O₅@carbon/reduced graphene oxide (M-Nb₂O₅@C/rGO) composites are fabricated by annealing the precursor of graphene oxide supported Nb-based metal organic frameworks for the first time. The lithium ion capacitor using M-Nb₂O₅@C/rGO as the anode and activated carbon as the cathode delivers a high energy density of 71.5 W h kg⁻¹ and excellent cycling stability.
