Carbon nanofoam papers containing primarily 10 - 20 nm mesopores support high MnOx loadings ( 60 wt % ) and device - level capacitance ( 30 F g ( - 1 ) ) , but the small mesoporous network hinders electrolyte transport and the low void volume restricts the quantity of charge - compensating ions within the electrode , making the full capacitance only accessible at slow rates ( 5 mV s ( - 1 ) ) .
