In the present work nickel-cobalt oxide nanocomposite were prepared using well known co-precipitation method. For comparison nano nickel oxide and nano cobalt oxide was also prepared. The samples were annealed at 500°C and characterized using SEM, TG, FTIR, XRD and UV. The dielectric studies at various frequencies of nickel-cobalt oxide nanocomposite were also done. The results showed that the capacitance of the as prepared and the annealed samples varied from milli farad to pico farad range. From this study it can be concluded that the present material by proper tuning can be used as a supercapacitor.
