Summarising, our analysis suggests that both the sizes of the graphene-like domains and the ion adsorption capacity are key factors that determine the capacitance of nanoporous carbons. Raman spectroscopy measurements show similar results with respect to disorder, with carbons having smaller ID/IG values and larger D band full width half maxima (FWHM) generally exhibiting higher gravimetric capacitance (Figure ), aligning with other previous observations. 32 While both techniques suggest that low temperature-synthesised carbons have smaller graphene-like domains, it is worth noting that Raman spectroscopy does not provide information on the ion adsorption capacity of the carbons, and therefore NMR provides a more complete picture.
