Abstract
MnO2 nanowires, 5-10 mu m long and ca. 20 nm in diameter, were intercalated with the RGO layers and Co3O4 nanoparticles. The MnO2 nanowire-incorporated ternary composites electrodes exhibited significantly higher specific capacitance than the RGO/Co3O4 binary composite in supercapacitors. The ternary composite exhibited a high rate capacitance, such as 1560 F g(-1) of specific capacitance at current density of 2 A g-1, as well as excellent cycling stability (94.1% capacitance retention after 1500 cycles). The ternary composite approach offers an effective methodology for enhancing the device performance of metal-oxide based supercapacitors for long cycling applications. (C) 2015 Elsevier B.V.
