【摘要】 以CO2活化酚醛树脂所得活性炭为电极材料,采用不同浓度无机电解液(LiCl、NaCl和KCl)组装成纽扣式双电层电容器,并对其进行恒流充放电和循环伏安测试,考察电容器的电容性能．运用低温 N2吸附表征活性炭的比表面积和孔结构．实验结果表明,KCl更适于作双电层电容器的电解液,高流量 CO2活化时所得活性炭对比电容的提高有利．更多还原

【Abstract】 In this work, the electrode material was the carbon activated with different speed of CO2 to phenol resin, and the performance of the capacitors was tested in KCl,NaCl and LiCl of different concentration. These four carbons were characterized by using N2 adsorption. Results showed that the specific capacitance of material enhanced due to the higher speed of CO2 and KC1 is fit for super capacitor as electrolyte without corrosion.更多还原
