Abstract
The effect of nickel oxide such as NiO1+x and LiNiO2 in the Ni based composite anode on the physico-chemical properties of oxidized layer formed on the composite anode prepared by sintering or dispersion coating method was studied. The galvanostatic and potentiostatic polarization behaviors of the Ni, the Ni-NiO, and the Ni-LiNiO2 composite anodes were investigated to elucidate the anodic processes. The electrical conductivity of the oxidized layer formed on the Ni-NiO and the Ni-LiNiO2 composite anodes was large in a well dehydrated melt of NH4F·2HF and its resistance to corrosion during polarization at potentials higher than 4.6 V vs. H2 was high compared with those on the Ni anode, because of the higher content of nickel oxide in the oxidized layer on the anode.Keywords
