Effects of Different Electrolyte Concentrations and Scan Rates in Mesoporous Carbon Electrode-Based Capacitance

Article Preview

Abstract:

A series of mesoporous carbon sample had been synthesized by using a modification of template silica, SBA-15. Sucrose was added into a large pore size of SBA-15 by using incipient wetness impregnation method. A proper carbonization and removal silica process had been done to produce large pore size of mesoporous carbon. Two electrode cells were prepared by coating mesoporous carbon into stainless steel mesh as a supercapacitor electrode. A few of electrolyte concentration also had been investigated by cyclic voltammetry using a various concentration of KOH in the range 1-12 M. It shows that 6M KOH gives a better performance of EDLC.
