Paper Title:
High-Temperature Performance of Amorphous Nickel Hydroxide Coated with La(OH)3
  Abstract

La(OH)3 coated amorphous nickel hydroxide was prepared by chemical coprecipitation method. The microstructure, surface morphology and chemical composition of the prepared sample were analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS). Electrochemical performances of the sample were characterized by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and charge/discharge measurements. The results demonstrated that the coating of La(OH)3 dramatically decreased electron transfer resistance and increased oxygen evolution potential of amorphous nickel hydroxide. Moreover, the high-temperature performance of amorphous nickel hydroxide was significantly improved after the coating of La(OH)3.
