摘要:
 针对活性炭电极超级电容器性能偏低的问题,依据双电层电容器工作原理,以活性炭、
乙炔黑、质量分数为15%的聚四氟乙烯、异丙醇为原料,采用粉末压片技术,制备了活性炭质量分
数分别为60%、65%、70%、75%和80%的超级电容器电极材料。通过扫描速率分别为5 mV/s、10
mV/s、20 mV/s、50 mV/s、100 mV/s 和200 mV/s 的循环伏安测试,分析了活性炭电极的比电容、比
能量和比功率。结果表明,当活性炭质量分数为70%、扫描速率为5 mV/s 时,比电容为189. 3 F /g,
比能量为26. 3 W·h /kg; 当活性炭质量分数为70%、扫描速率为20 mV/s 时,比功率为916. 6 W/kg。
确定了电极材料中活性炭的最优配比为70%,为基于活性炭电极的超级电容器制备提供了重要

Abstract:
 For the problem of lower performance of supercapacitors based on activated carbon,according to a
working principle of an electric double layer capacitor,activated carbon electrodes with mass fractions of 60%,
65%,70%,75% and 80% were prepared by a powder compression technology. Activated carbon,acetylene
black,PTFE with the mass fraction of 15% and isopropanol were used as raw materials. The specific capacitance,
the specific energy and the specific power of the activated carbon electrodes were analyzed through cyclic
voltammetry tests with scanning rates at 5 mV/s,10 mV/s,20 mV/s,50 mV/s,100 mV/s and 200 mV/s. The
results show that the specific capacitance is 189. 3 F /g and the specific energy is 26. 3 W·h /kg when the mass
fraction of activated carbon is 70% and the scanning rate is 5 mV/s. The specific power is 916. 6 W/kg when the
mass fraction of activated carbon is 70% and the scanning rate is 20 mV/s. This study confirms the optimal ratio of
the mass fraction of activated carbon is 70%,providing an important reference for preparation of supercapacitors
based on activated carbon electrodes.
