To extract the sizes of the graphene-like domains in the synthesised nanoporous carbons, we conducted NMR simulations based on our previously established method, and as applied in previous studies (Figure ). In general, the synthesised carbons follow the trend observed in our previous study that carbons with smaller calculated ordered domain sizes generally have higher capacitance. Here our new lowtemperature synthesised carbons have both smaller graphene-like domains and larger capacitances compared to our previous commercial activated carbon series, extending the limits of our master plots (Figure ).
