  1. In summary, the optimal production conditions of GIC were as follows: the ball milling media was stainless-steel beads, the size of the ball milling media was 6 mm, ball mill time was 4 h, ball mill speed was 500 r/min, the decomposition temperature was 200 ℃, the decomposition time was 4 h, and the mass ratio of flake graphite to NaHCO3 was 1:1
  2. At this condition, the expansion volume of GIC was 142 mL/g
