摘要:
以新型碳材料——碳原子线为超级电容器电极材料.碳原子线由天然高分子淀粉高温催化热解而得,并通过浓硝酸处理的方法对其进行表面官能化.酸处理后碳原子线电极的电容性能测试采用循环伏安法,恒流充放电法和交流阻抗法.实验结果表明,酸处理后的碳原子线电极显示出较高的电容性能,在5 mol/L硫酸水溶液中,在0.2 A/g的放电电流密度下,该电极的比电容可达256 F/g,同时具有较低的等效串联电阻和较好的循环稳定性.
Abstract:
A novel carbon m a terial nam ed carbon atom w ires( CAW ) is used fo r e lec trode m ater ia l in supercapacitors. The CAW is fabricated by the py ro lysis o f starch cata lyzed by Fe and treated by concentrated nitr ic ac id to be surface functionalized. The capac itance per fo rm ance of the trea ted- CAW e lectrode is investigated by use o f the cyc lic vo ltamm etry, ga lv anosta tic charge /d ischarge and AC im pedance me thods. The resu lts show ed that the specific capac itance o f 256 F /g o f the e lectrode is ach ieved w ith the d ischarg e current density of 0.2 A / g in the solution o f 5 mo l/L H2 SO 4. In add ition, the treated-CAW e lectrode is found to have low equivalen t ser ies resistance ( ESR) and good cyc ling stab ility.
