  • 摘要: 以花生壳为原料,氢氧化钾为活化剂,采用微波加热制备出活性炭,所制活性炭用于制备电化学电容器用电极材料。通过氮气吸附、恒流充放电及循环伏安对所制活性炭的孔结构及电化学性能进行研究。结果表明,活性炭的比表面积、总孔容、比电容以及能量密度在炭化时间(6-10min)以及KOH与花生壳的质量比(0.6-2.0)的范围内存在最大值。当KOH/花生壳的质量比为1.0,微波功率为600W,活化时间8min,所制活性炭(AC1-600-8)比表面积达1277m2/g,并且经1000次循环后,其能量密度高达8.38Wh/kg。因此采用微波加热、KOH活化是一种快速制备电化学电容器用活性炭的低成本方法。
