Five kinds of mesoporous carbons (disordered mesoporous carbons (DMCs) which contain ink bottle (DMC-1) and cylinder structure (DMC-2), ordered mesoporous structure (OMCs) including lamellar (OMC-1), hexagonal (OMC-2) and cubic structure (OMC-3)) were selected to study the morphology and temperature on the electrochemical capacitive performance. Cyclic voltammetry and galvanostatic charging−discharging measurements are performed, and the results show that the OMC-2 has the best integrated

Moreover, the temperature on the pore structure and electric performance of DMCs was also studied, and the results show that too high temperature(1600°C) would result in disruption of pore structure which would further lead to the worse electric performance.
