Note: The particle size of CB was measured by TEM, and the nitrogen surface area (NSA) was determined by the nitrogen adsorption/desorption profiles at −196 °C from P/P0 = 0.05 to 0.30 according to the Brunauer–Emmett–Teller (BET) method based on ASTM D6556. STSA means statistical thickness surface area, which represents the external surface area of CB according to ASTM D6556. Oil adsorption number (OAN) stands for the particle packing style of CB according to ASTM D1765. Ash content was measured based on the method in ASTM D1506-15.
