In 2018, Sun et al. [ 20] proposed an electrochemical method to prepare exfoliated graphite at high yields using a ternary deep eutectic melt containing acetamide, urea, and ammonium nitrate. However, this method requires specific electrolytes and electrode materials, which is not conducive for commercial mass production.

When grinding, screening, or otherwise reducing the particle size of flake graphite, cleavage parallel to the basal plane (basal pinacoid) occurs. The result is the creation of thinner flakes with subsequent reduction of the expansion potential of those flakes. The effect of particle size on graphite exfoliation has good empirical support.
