Nickel oxide is a promising material for supercapacitors owing to its high theoretical specific capacitance; however, its practical capacitance is far below the theoretical limit. In this work, we report a novel Ni/NiO composite supported by carbon nanofibers as a pseudocapacitor electrode. Characterization of this sample by X-ray diffraction, transmission electron microscopy, scanning electron microscopy, X-ray photoelectron spectroscopy, Brunauer-Emmett-Teller analysis, and contact angle… CONTINUE READING
