摘要/Abstract

摘要： 以碳酸丙烯酯(PC)和碳酸乙烯酯(EC)作增塑剂,LiClO4作支持电解质,高比表面积活性炭为电极,内聚合法制作PMMA-PC+EC-LiClO4体系凝胶聚合物电解质(GPE)双电层电容器.应用交流阻抗、循环伏安、恒流充放电等方法研究了该电容器的性能.结果表明,PMMA-GPE的离子电导率在室温下达3.7 mS.cm-1,电容器的工作电压达3 V,比容量达41.6 F.g-1(I=1 mA.cm-2),等效串联电阻仅为几欧姆.

Abstract: Polymethyl methacrylate(PMMA) based gel polymer electrolytes electrochemical double layer capacitors(GPE-EDLCs) were fabricated by an in situ polymerisatonal method with actived carbon electrodes,using propylene carbonate(PC) and ethylene carbonate(EC) as plasticizer,lithion perchlorate as surporting electrolytes.The ion conductivity values of GPEs were evaluated by AC impedance.The properties of PMMA-based GPEs capacitors were researched by impedance spectrum,cyclic voltammetry,galvanostatic charge-discharge.It showed that the ion conductivities of the PMMA-based gel polymer electrolytes reached to 3.7 mS·cm-1 at ambient tempreture.The working voltage of the capacitors reached to 3.0 V.The specific capacitance of the capacitor was obtained as high as 41.6 F·g-1(I=1 mA·cm-2).The equivalent serial resistance of the capacitors were just several Ohm.

Key words: EDLCs, gel polymer electrolytes, PMMA, plasticizer, activated carbon
