Tóm tắt

Successfully fabricated porous carbon (CDC) nanomaterials from coke (CD) by Hummer method. The fabricated nanomaterials are porous, with an average size of 30 - 40 nm. CDC electrode works well, stably with capacitance retention of 74.7% after 1000 cycles. The constant current discharge method determined the CDC specific capacitance to be 118 F/g corresponding to a current density of 0.01 A. The specific capacitance decreased with increasing current density. CDC electrodes conducted electricity well. The charge transfer resistance was very small. The results on the electrochemical properties of the material showed that the energy storage capacity of the CDC material was good and stable.
