Synthesis of a MnO 2 Nanosheet/Graphene Flake Composite and Its Application as a Supercapacitor having High Rate Capability

Synthesis of a MnO 2 Nanosheet/Graphene Flake Composite and Its Application as a Supercapacitor... Hydrothermal treatment of KMnO4 and graphene flakes (GFs) leads to MnO2 nanosheets decorated on GFs. The resulting MnO2/GF (MG) composite has been tested as a supercapacitor electrode in aqueous electrolyte and found to exhibit good cycling stability with a specific capacitance of 147 Fg−1 at a current density of 5 Ag−1 (see figure). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png ChemPlusChem Wiley

Abstract

Hydrothermal treatment of KMnO4 and graphene flakes (GFs) leads to MnO2 nanosheets decorated on GFs. The resulting MnO2/GF (MG) composite has been tested as a supercapacitor electrode in aqueous electrolyte and found to exhibit good cycling stability with a specific capacitance of 147 Fg−1 at a current density of 5 Ag−1 (see figure).
