摘要：
In this work, NiWO4 was prepared by co-precipitation and modified by ultrasonic and laser irradiation. Its electrochemical properties were investigated by potentiodynamic, galvanostatic and impedance spectroscopy methods. The results show that NiWO4 ultrasonic-modified and exposed to laser irradiation for 420 s has the highest capacitance of 520 F/g at a discharge current of 1 mA. This capacitance value is 2.5 times higher than for NiWO4 ultrasonic-modified and 3.4 times higher than for NiWO4 obtained by co-deposition. The capacitance enhancement of NiWO4 modified by ultrasonic and laser irradiation is the result of stimulation of fast redox reactions, which is confirmed by impedance studies.
