In this work, nickel and cobalt binary sulfide nanoparticles are successfully decorated on the surface of multi-walled carbon nanotubes to form a composite (Ni-CoS/MWCNT) via a facile glucose-assisted hydrothermal method. By introducing the conductive MWCNT and tuning the Ni/Co molar ratio for the Ni-CoS/MWCNT composites, the optimized one shows a high capacity up to 153 mAh g(-1), superior rate capability and excellent electrochemical stability. On this basis, advanced hybrid supercapacitor (HSC) is assembled by using the Ni-CoS/MWCNT composite as the cathode and reduced graphene oxide as the anode. As-fabricated HCS is able to be operated reversibly in a full voltage region of 0-1.6 V and achieves a high specific capacity of 33 mAh g(-1) at 1 A g(-1), therefore delivering a maximum energy density of 23 Wh kg(-1) at a power density of 684 W kg(-1). Furthermore, the HSC still retains 90% of its initial discharge capacity after 2000-cycle consecutive charge/discharge test at 4 A g(-1). (C) 2015 The Electrochemical Society.
