摘要：

Both structural and electrochemical properties of non-doped nickel hydroxide produced by a new synthesis route of electrodialysis are investigated. A comparison with two spherical beta-type Ni(OH)(2) is made. Structural characterization is carried out by X-ray diffraction, vibrational spectroscopy and thermal analysis. Electrochemical properties are studied by cyclic voltammetric and chronoamperometric experiments. The material obtained by electrodialysis is found to have a highly defective structure, which corresponds to a complex electrochemical behavior. More particlarly, it is shown that this new nickel hydroxide is more stable regarding the beta -> gamma transformation.
