Structure and Electrochemical Performance of Cu and Al Codoped Nanometer α-Nickel Hydroxide

Abstract:

Nanometer α-nickel hydroxide codoped with Cu and Al has been synthesized by the ultrasonic-assisted precipitation method. The crystal structure and particle size were analyzed by X-ray diffraction (XRD) and particle size distribution (PSD). The electrochemical performance of the samples was characterized by the charge/discharge test and cyclic voltammetry. The results of electrochemical tests demonstrated that the speciﬁc discharge capacity of Cu/Al codoped α-nickel hydroxide (330 mAh/g) is much higher than that of pure spherical nickel (240 mAh/g), and it exhibits a relatively good electrochemical reaction reversibility and large proton diffusion coefficient.
