Abstract
The electrochemical process of intercalation-deintercalation of sulphuric acid into chromium trioxidegraphite intercalation compounds (CrO3-GICs) has been studied using 12 M H2SO4. It is shown that the anodic oxidation reactions of CrO3-GICs and cathodic reduction of the product of anodization are different when compared to those occurring in the pure graphite. The differences in the slow cyclic potentiodynamic curves, depending on the method of preparation of CrO3-GICs, are considered. The practical implications of the electrochemical transformation of CrO3-GIC for battery applications are shown.
