摘　　要：介绍了以商用活性炭为电极材料组装成的超级电容器正、负极的自放电曲线和自放电速率的变化;研究了电极电位对电容器自放电性能的影响。研究结果表明:负极自放电的影响大于正极,即超级电容器的自放电速率基本由负极自放电速率决定。The electrodes made of commercial-available activated carbon were assembled to symmetry electric double-layered capacitor. The self-discharge curve and self-discharge rate variation of the supercapacitor were introduced in this paper. The effects of electrode potential on self-discharge were studied. The results showed that the self-discharge of negative electrode was greater than that of positive electrode, the self-discharge rate of supercapacitor was determined by self-discharge rate of negative electrode basically.
