) and ion adsorption capacities (0.6-0.8 mmol g -1 ), in which case the capacitive performance was more strongly dominated by the sizes of the graphene-like domains. However, with a wider range of nanoporous carbons including carbons with evidently large (HTC-750; 1.24 cc g -1 and HTC-750_1; 0.93 cc g -1 ) and small (HTC-1200_1; 0.32 cc g -1 ) pore volumes, a correlation is observed (Figure ). between gravimetric capacitance and F Δδ values, with commercial activated carbons, their thermally annealed counterparts and CDC data added from previous studies. (c) Relationship between gravimetric capacitance and calculated ordered domain size of the synthesised nanoporous carbons, with commercial activated carbons, their thermally annealed counterparts and CDC data added from previous studies. (d) Correlation between gravimetric capacitance and edge length per unit area for synthesised carbons, with commercial activated carbons and their thermally annealed counterparts data added from previous studies. See Methods for detailed definitions of the edge length per unit area.
