The Effect of Morphology and Temperature on the Electrochemical Capacitive Performance of Mesoporous Carbons Synthesized Using Reverse Copolymers

摘要

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 morphologyand temperature on the electrochemical capacitive performance. Cyclic voltammetry and galvanostaticcharging?discharging measurements are performed, and the results show that the OMC-2 has the bestintegrated electrochemical performance owning to synergistic effects of the hexagonal mesostructuredand ordered pore arrangement. Moreover, the temperature on the pore structure and electric performanceof DMCs was also studied, and the results show that too high temperature(1600°C) would result indisruption of pore structure which would further lead to the worse electric performance.
