In this work first described the new relatively simple approach to the synthesis of nanolayers of Ni-doped CuO via of Successive Ionic Layer Deposition (SILD) method. The study of Ni-doped CuO nanolayers, synthesized of SILD, has been carried out by HRTEM, XRD, FTIR and XPS spectroscopy methods; it was demonstrated that they had been formed of nanorods with dimensions of about 10-15 nm and tenorite crystal structure CuO were formed. The research electrochemical properties of nanolayers were carried out in 1 KOH solution by using techniques of cyclic voltammetry and galvanostatic curves method. The electrochemical study of nickel foam electrodes modified by Ni-doped CuO nanolayer prepared by 30 SILD cycles demonstrates that specific capacitance is 154 mAh/g (1240 F/g) at current density 1 A/g. Repeated cycling after 1000 charge-discharge cycles demonstrates 8% capacitance fade from the initial value, so such electrodes may be used as effective electroactive materials for alkaline battery and pseudocapacitors.
