Toward high practical capacitance of Ni(OH)2 using highly conductive CoB nanochain supports

Ultrathin porous Ni(OH)(2) sheets were grown on the surface of nano-chain CoB as cores via a facile two-step solution-based method at ambient conditions. The resultant CoB@Ni(OH)(2) of 27.89 wt% Ni(OH)(2) loading has a high specific capacitance of 1504.4 F g(-1) at 0.5 A g(-1), 1293.7 F g(-1) at 2 A g(-1) and 746.8 F g(-1) at 6 A g(-1).
