本文选用NaO H与KO H为活化剂，通过化学活化法制备煤基活性炭，分析了活化剂对活性炭电化学性能的影响。通过X RD分析可知，自制活性炭属于无定型炭。从电化学性能图分析，部分活性炭具有明显的氧化还原峰，能够提供较高的赝电容，电化学性能较好。NaO H ：KO H ：煤＝2∶2∶1样品随着电流密度的增大，比电容衰减较小，电容保持率高，电化学性能优异。

By selecting NaOH and KOH as chemical activators to prepare coal‐based activated car‐bon ,this paper analyzed the electrochemical performance of the activated carbon with different propor‐tion of quality activator .The XRD pattern showed that the self -made activated carbon belongs to the amorphous carbon .The electrochemical performance chart shows that part of the activated carbon has obvious redox peak ,capable of providing a higher pseudo capacitance as depicted .The electrochemical performance is better for a sample of the composition of NaOH ∶KOH∶coal=2∶2∶1 .With the in‐crease of current density ,the specific capacitance attenuates ,and high capacitance retention is mainta‐nined .
