Second, we find that carbons with smaller ID/IG values have higher capacitances (Figure ), supporting our previous findings from NMR spectroscopy that carbons with smaller graphene-like domain sizes have higher capacitances (Figure ). Strikingly, the plots of (i) capacitance vs. ID/IG (Figure ) and (ii) capacitance vs. the NMR-derived ordered area (Figure ) show very similar correlations. This can be rationalised since in Stage 2 of Robertson and Ferrari's model the ID/IG value is proportional to the area of the ordered graphene-like domains (the square of La), i.e., both correlations show that capacitance increases for porous carbons with smaller graphene-like domains (Figure ). To further compare the insights from the two techniques, we plotted the ordered areas from NMR simulations against the ID/IG intensity ratios from Raman (Figure ). Nanoporous carbons with smaller ordered areas from NMR simulations also show smaller ID/IG values, with a linear correlation between the two parameters (Figure ). This supports the idea above that the two techniques provide two different measurements of the areas of the graphene-like domains. There is, however, an important distinction between the two different spectroscopic probes of the areas of the graphene-like domains, which may manifest in future measurements of a wider range of carbon materials. Specifically, the NMR spectroscopy approach measures structural disorder as experienced by the electrolyte ions adsorbed in the carbon pores (achieved through measurement and simulation of the ring current shifts for the adsorbed electrolyte ions). In contrast, the Raman spectra measure the carbon disorder irrespective of any electrolyte sorption, and provide an overall measurement of disorder throughout the carbon, regardless of whether electrolyte ions can actually access the various carbon surfaces. Therefore the NMR approach provides more targeted information, providing both the in-plane domain sizes as experienced by adsorbed ions, as well as the in-pore ion adsorption capacities via integration of the resonances from in-pore ions. For the series of carbons studied here, all the materials are highly porous with a BET surface area larger than 1000 m 2 /g, and the electrolyte ions are able to access the material porosity in all cases. In this scenario the ordered areas measured by NMR and the ID/IG ratio are correlated with each other (Figure ), and both are inversely correlated with capacitance (Figure ). However, we should also consider the hypothetical scenario of a porous carbon with very limited porosity accessible to the electrolyte ions -a case where low capacitance would be expected. In this scenario the ordered area probed by NMR spectroscopy may no longer be correlated with the ID/IG ratio from Raman. While the Raman spectra would still measure carbon disorder, they would give no indication of whether electrolyte can access the pores or not. In contrast, the NMR spectra would reveal a very low uptake of electrolyte ions in the carbon pores (through a low in-pore peak integral), and would lead to the expectation of low capacitance.
