(a) CV curves of Ni(OH)2/MWNT hybrid at various scan rates in 1 M KOH. (b) Average specific capacity of Ni(OH)2 nanoplates grown on oxidized MWNTs at various scan rates based on CV data in (a). (c) Average specific capacitance within a voltage range of 0.55 V (from 0 V to 0.55 V vs SCE) of Ni(OH)2 nanoplates grown on oxidized MWNTs at various scan rates based on CV data in (a). (d) Cycling stability of the Ni(OH)2/MWNT hybrid electrode over 1,000 CV cycles at 100 mV s−1. Loading of Ni(OH)2/MWNT was ~1.1 mg cm−2 for the electrode.
