中文摘要：
以沥青焦为原料，采用KOH活化法制备了具有高比表面积的超级活性炭（SAC），采用N2吸附、X射线衍射（XRD）和X射线光电子能谱（XPS）对其孔结构、微晶结构以及表面官能团进行了表征，研究了其作为超级电容器电极材料在1mol／L的Et4NBF4／碳酸丙烯酯电解液体系中的电化学特性。结果表明，所制活性炭的比表面积（SBET）达2893m^2／g，孔径主要分布在1—4nm范围，其质量比电容（Cm）和能量密度分别达到190F／g和59W·h／kg。
英文摘要：
A super-activated carbon（SAC） with high specific area has been prepared from raw pitch coke using KOH as activation agent. The pore structure, graphite- like crystallite structure and surface functional groups of SAC were studied respectively with N2 adsorption/desorption isotherms, X-ray diffraction（XRD） and X-ray photoelectron spectroseopy（XPS）. The specific capacitance of SAC was measured in lmol/L Et4NBF4/propylene carbonate electrolyte. Results indicated that SAC has higher specific surface area （2893 m^2/g） and the pore size is mainly distributed in the range of 1 to 4 nm. The weight specific capacitance and energy density are 190 F/g and 59 Wh/kg respectively.
