Abstract
The electron structure of the NixTiSe2 system has been studied by the electromotive force (EMF) method in Cu|Cu+|NixTiSe2 and Na|Na+|NixTiSe2 electrochemical cells. Two critical transitions have been found in this system at x = 0.25 and x = 0.35. At these compositions, a change in the nature of the chemical bond of nickel with its local environment occurs. The simple and useful EMF method has been applied as the instrument to study features of electron structure. A comparative analysis of critical points in the electronic structure of the MexTiSe2 (Me = Fe, Co, Ni) intercalate compounds was carried out.
