Figure 12. Oxidation of graphite by targeted spraying of the blue GIC with water. Image 1: Blue graphite intercalation compound. Image 2 & 3: Spraying the GIC with water. Color change due to the strong oxidation of graphite. Image 4 & 5: The gradual mixing of the organic electrolyte with water oxidizes the entire graphite surface. Image 6: After 5 minutes of electrolysis, exfoliation takes place on the graphite foil, whereby large yellow flakes break off
