摘要
采用常压干燥法制备了炭气凝胶,对所制得的炭气凝胶进行了电化学性能的测试,并与日本进口的超级电容器用超级活性炭进行比较。实验结果表明,炭气凝胶具有优良的电容性能,电双层比电容量和高扫描速度下(100mV/s)的质量比电容量分别达到21μF/cm2和89F/g,高于日本进口超级电容器用超级活性炭。
In this paper, carbon aerogel was synthesized by ambient pressure drying. The electrochemical properties of carbon aerogel ware studied. The results showed that carbon aerogel electrodes exhibited excellent electrochemical behavior. Compared to the commercial super activated carbon imported from Japan, carbon aerogels had better mass specific capacitance at high sweep rate (100mV/s)and electric double layer (EDL) specific capacitance (89F/g and 21μF/cm^2 respectively).
