✦ Synopsis

By means of cyclic voltammetry, a study of the redox reactions has been made on stage 1 sulfuric acid-graphite intercalation compound (H,SO,-GIC) prepared by anodic oxidation of graphite in sulfuric acid electrolyte. It was found that further oxidation of the stage 1 GIC gives rise to the reversible ionization reaction of carbon atoms in the graphite basal plane and also of sulfuric acid molecules produced in the interlayer spacing. This ionization reaction and the reverse deionization reaction are responsible for plateaus observed in the current vs. potential curve. These redox reactions between the stage 1 GIC and its ionized state were analyzed in situ by means of X-ray diffractometry.

The relation between the compositions of alkali metal-graphite intercalation compounds and the crystallite size of pristine graphite was mathematically analyzed taking into account the inplane structure and the stacking sequence of the graphite intercalation compounds. It has been found that the ato
