Nano nickel oxide (NiO) is synthesized facially and hydrothermally. XRD confirms FCC as NiO crystal structure. FT-IR proves functional groups and purity levels. NiO electrochemistry is fully revealed using CV, GCD and EIS, in 1M KOH electrolyte. CV identifies the PC behavior of NiO, via observing redox peaks. Furthermore, the GCD curve exhibits the specific capacitance 185F/g, at a current density 0.3A/g, with superior cyclic stability of 93%, up to 1500cycles. Research results confirm the Nano
