The samples were analyzed by N2 adsorption, scanning electron microscopy （SEM）. Cyclic voltammetry and galvanostatic charge-discharge were used to characterize the electrochemical performance of the samples. The results showed that the pore size was mainly in the range of 0.5-9.0 nm. Supercapacitors based on the sample AC （Activated carbon） have low ESR and excellent power property.展开更多
