Abstract
Using the method of electrochemical analysis the charge capacity of electrochemical cells with cathode material on the bases of simple and mechanically activated mixtures 0,2α-Fe2O3+0,8Al2O3, 0,2α-Fe2O3+0,8SiO2 та 0,2γ-Fe2O30,8SiO2 has been researched. With the help of method of ultra soft X-ray spectroscopy the influence of mechanical activation method on the distribution of valence electrons of these mixtures has been researched. In this research, the relationship between changes in populations of electronic states in the valence band and intercalation properties of studied mixtures has been studied.
