摘要/Abstract

摘要： 以椰壳炭化料为原料,KOH为活化剂,在不同工艺条件下制备了超级电容器用活性炭电极材料。考察了碱炭比、活化温度和活化时间对活性炭孔隙结构及其用作电极材料的比电容的影响。结果表明,在KOH与椰壳炭化料质量比为4:1,活化温度800℃,活化时间60 min的条件下,可制得比表面积2891 m²/g,总孔容积1.488 cm³/g,中孔率73.6%,比电容达235 F/g的优质活性炭电极材料。

Abstract: Activated carbon for supercapacitor was prepared from coconut shell carbide by KOH activation. The effects of the ratio of KOH/carbon, activation temperature and activation time on the pore structures and specific capacitance of activated carbon were investigated. The results showed that the high quality activated carbon as electrode material could be prepared under the conditions of the mass ratio of KOH/carbon 4:1, activation temperature 800℃ and activation time 60 min. Under these conditions, its specific surface area of the sample was 2 891 m²/g, total pore volume was 1.488 cm³/g, the mesopore ratio was 73.6 % and specific capacitance was 235 F/g.

Key words: coconut shell carbide, activated carbon, electrode material, supercapacitor, specific capacitance
