摘　　要：通过过热蒸气活化法制备的柏木炭中含有大量的中孔,可用于制备以1mol/L硫酸为电解液的双电层电容器(EDLCs)。在50mA/g电流密度下,柏木炭的质量比电容(C50)为190F/g;在1000mA/g电流密度下,其质量比电容(C1000)为140F/g。按C1000/C50定义的性能倍率约为0.72。测得的高电容量可归因于微孔和大孔所造成表面的贡献。以简易浸泡法负载少量NiO粒子后,柏木炭的质量比电容可以提高约13%,体积比电容提高约27%,而其性能倍率保持不变。Cypress charcoals, which were prepared under super-heated steam and had a relatively large amount of mesopores, were used in electric double layer capacitors （EDLCs） in 1 mol/L H2 SO4 electrolyte. The gravimetric capacitance of cypress charcoals was about 190F/g at a current density of 50mA/g （C50） and 140F/g at 1000mA/g （C1000） and the performance rating defined by C1000/C50 was about 0.72. The capacitance observed was explained by the contributions from the surfaces from the micropores and the larger pores. By loading minute NiO particles through a simple impregnating process, the capacitance of the loaded charcoals was enhanced by about 13% in gravimetric capacitance and by about 27 % in volumetric capacitance and the performance rating was kept the same.
