With a dataset of 23 nanoporous carbons including 10 commercial activated carbons, their thermally annealed counterparts at varying temperatures (Figure ), and three TiC-CDCs from previous studies, symmetric EDLCs with organic electrolyte (1 M NEt4BF4 in acetonitrile). First, we find that carbons with larger D band FWHMs tend to have higher capacitances (Figure ). This supports the idea introduced above that carbons with broader distributions of graphene-like domain sizes exhibit enhanced capacitances.
