Abstract

Sponge-like porous Ni(OH)2-NiF2composite (PNC) film was successfully synthesized by the anodization of nickel in a NH4F and H3PO4containing electrolyte. Thanks to the good conductivity and the highly porous architecture, PNC exhibited not only a high specific capacitance, but also a superior rate capability and a good cyclability (2090 F g-1at 10 mV s-1, capacitance >1200 F g-1at 100 A g-1after 2000 cycles). Anodization of nickel is proven to be fast and facile and can be easily scaled up. The method described here is promising for the fabrication of supercapacitor electrodes with excellent performance.
