摘　　要：以KOH为活化剂,对中间相炭微球(MCMB)进行化学活化处理,制备了具有高比表面积和发达孔道结构的多孔炭材料,并探究此材料作为电极材料在超级电容器中的应用。结果表明:当KOH和MCMB的质量比为5:1时,MCMB表面的大量微孔结构被进一步刻蚀成介孔结构,且出现了大面积裂痕,但不破坏MCMB的球形度。将此材料应用在超级电容器的电极材料上,体现出良好的充放电可逆性,较高的比电容(在0.5 A/g和5 A/g的电流密度下的质量比电容分别为195 F/g和160 F/g),较高的功率密度(1251.0 W/kg),较小的内阻(0.462Ω)。KOH was used as an activator to chemically activate mesocarbon microbead(MCMB),so as to prepare the porous carbon material with high specific surface area and well-developed pore structure,and the application of this material as an electrode material in supercapacitors was explored.The results showed that when the mass ratio of KOH to MCMB was 5∶1,a large number of microporous structures on the surface of MCMB were further etched into mesoporous structures,with large area of cracks,but the sphericity of MCMB was not destroyed.When applying this material to the electrode material of the supercapacitor,the activated MCMB showed good reversible charge-discharge behavior,high specific capacitance(mass specific capacitance of 195 F/g and 160 F/g at current densities of 0.5 A/g and 5 A/g,respectively),high power density(1251.0 W/kg),and low internal resistance(0.462Ω).
