摘　　要：以石油焦为原料,KOH为活化剂,经微波加热活化,制备出了超级电容器用高性能活性炭电极材料。以制得的活性炭制成的电极片为电极,6mol/L的KOH溶液为电解液,组装了模拟电容器。研究了加热时间和碱焦比对活性炭比表面积及电容器性能的影响。研究表明:在KOH与石油焦按3∶1的质量比混合,微波辐射时间为15min时,制备的活性炭比表面积达2683m2/g,模拟电容器单电极比电容量达361F/g。High performance activated carbon electrode material for supercapacitor was prepared by heating the mixture of petroleum coke and KOH catalyst in a microwave oven. Supercapacitors were assembled with the electrolyte of 6 mol/L KOH solution and the electrodes made from the prepared activated carbon. The effects of heating time and mass ratio of KOH to petroleum coke on the specific surface area of the activated carbon and the performance of the supercapacitor were studied. The results show that when the mixt...
