Mean State

The electrode potential of the nickel oxide electrode has been determined as a function of water and solute activity in aqueous solutions of potassium hydroxide. The electrode, which was charged to a mean state of oxidation corresponding to 50% Ni II and 50% Ni III, was examined after long periods of time and by cathodic and anodic e.m.f. decay measurements after polarization in order to establish the quasi-reversible potentials by two methods. The results are discussed in terms of the stoichiometry of the potential-determining reaction, and distinction between mixed and true reversible potentials is made.

Lithiated nickel oxide films were thermally synthesized using Ni / Li / Ni films at various temperatures between 873 K and 1123 K. Structural and electrochemical properties of the synthesized films were investigated by means of X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and galvanostatic charge–discharge half-cell tests between 4.5 V and 2.5 V. Lithiated nickel oxide films with the composition near stoichiometric LiNiO 2 could be obtained under annealing conditions (973–1073 K, 1 h). Surfaces of synthesized films consisted of some particles and became smoother with an increase in annealing temperature. Particles with the sharpest edge were formed at 1023 K. Cells with synthesized electrodes showed reversible Li ion transfer and clear voltage plateaus in charge–discharge curves that can confirm the phase transformation of LiNiO 2.
