Applications of New Activated Carbon Meterials in the Electric Double-layer Capacitor

Abstract

 以椰壳为原料,利用特定的物理 化学方法在一定条件下制得双电层电容器活性炭电极材料.实验表明,该活性炭经压制成型后制作的双电层电容器,具有大的比电容,文中同时研究了酸处理、二次活化以及电极冷压成型方法对电极性能的影响.A new type activated carbon whose precursor was coconut shell could be obtained using specific physics-chemistry activation, and the activated carbon was applied as the material of electrode in EDLC(electrical double-layer capacitor),which had a large specific capacitance,and could charge and discharged in some large currents. Carbon dioxide and acid were used to modify carbon,and the effects of post-treatment on surface area and pore volume were investigated. A moulding method which has influence on some properties of carbon electrode with PTFE additive was researched in the paper.作者联系地址:上海大学环境与化学工程学院,上海大学理学院化学系,上海大学理学院化学系,上海大学理学院化学系,上海大学理学院化学系,上海大学理学院化学系,上海大学理学院化学系 上海200072 ,上海200436 ,上海200436 ,上海200436 ,上海200436 ,上海200436 ,上海200436Author's Address: 1, JIANG Hua~2,FANG Jian-hui~*2,SHI Li-yi~2,YIN Ren-he~2,WEN Yi~2, LIU Ji-quan~2 1.School of Environmental and Chemical Engineering,Shanghai University,Shanghai 200072,China, 2.
