MnO2/multiwall carbon nanotube/Ni-foam hybrid electrode for electrochemical capacitor

摘要：

　　The ternary composites of manganese dioxide/multiwall carbon nanotube/Ni-foam(MnO2/MWNT/Ni-foam)for supercapacitors were fabricated via a hydrothermal method after direct growth of MWNTs on the Ni-foam.The structural properties of the electrodes were characterized by SEM and TEM.The electrode exhibited excellent electrochemical properties from the investigation based on the three-electrode setup.Low contact resistance Rs of about 0.291 Ω between MnO2/MWNT and Ni-foam was reached benefited from the direct growth structure.High capacitance of 355.1 F/g at the current density of 2 A/g was achieved,with good capacitive response at high current density.The MnO2/MWNT/Ni-foam electrode exhibits good stability performance after 2000 cycles at a current of 40 mA.
