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-Fe₂O₃0,8SiO₂has 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.
