Abstract
Freestanding Ni(OH)2nanoflakes on CNT films (NNCF) electrode with high specific capacitance is effectively fabricated via a facile chemical precipitation method. The CNT films function as conductive networks and the nucleation centers of Ni(OH)2nanoflakes. The resulted ultrathin α-Ni(OH)2exhibits a high specific capacitance of 3351 F g−1at a scan rate of 2 mV s−1and a good cycling stability with a visibly low capacitance loss of 15% at a high scan rate of 70 mV s−1, suggesting promising potential for supercapacitor applications.
