摘要:
选取日本50F活性炭为电极材料,四氟硼酸四乙基氨盐/碳酸丙烯酯为电解液,从极片尺寸、极片所受压力、电极片在电解液浸泡时间研究影响超级电容器一致性制备的因素.结果表明:5组超级电容器电荷转移电阻减小,平均比容量从最初的94.6 F·g-1增加到110.8 F·g-1,提高17.1%;比容量方差从2.92降到0.20,一致性明显提高;经过1 000次循环,比容量保持率均在95.0%以上,循环稳定性强.
Abstract:
In this paper, 50F activated carbon from Japan was selected as electrode material, tetraethylammonium tetrafluoroborate/propylene carbonate as electrolyte, from the size of the electrode, the pressure of the electrode, the electrode immersion time in electrolyte to study on the influence factors of supercapacitors consistent preparation. Result show that, the impedance resistance of the five sets of supercapacitors was reduced, and the average specific capacitance increased from the initial 94.6 F·g-1 to 110.8 F·g-1, with an increase of 17.1%. The variance of the specific capacitance decreased from 2.92 to 0.20, and the consistency was obviously improved. After 1 000 cycles, the specific capacitance retention rate is above 95.0%, and the cycle stability is strong.
