Synthesis of Mixture Salt Activated Porous Carbon from Scaphium Scaphigerum and Its Performance as Super Capacitor Electrode Material
Abstract:
A series of porous carbons(PC-1,PC-2 and PC-3) with microporous and suitable mesoporous was successfully prepared by pyrolysis in the absence(PC-1) and existence of ZnCl2(PC-2),or ZnCl2/LiCl(PC-3) activators utilizing soaked scaphium scaphigerum as the precursor.The specific capacitance of PC-1,PC-2and PC-3 electrodes at the current density of 0.5 A/g in three-electrode system is 69,132 and 228 F/g,respectively.Moreover,a specific capacitance up to 166 F/g at the current density of 10 A/g indicates a good rate performance of PC-3.These desirable results reveal that the porous carbons prepared from scaphium scaphigerum by ZnCl2/LiCl activation can be used as high performance electrode materials in supercapacitor.
