摘要
通过水热活化/去甲基化复合改性的方法改性木质素,用聚乙二醇二缩水甘油醚((PEGDE)交联制得改性木质素薄膜并组装成超级电容器。系统研究了交联改性木质素薄膜的结构和性能,并分析了超级电容器的电化学性能。结果表明:当PEGDE添加量为200%时,超级电容器的电化学性能最好,在0.2 A·g^(-1)的电流密度下,质量比电容达到了181.82 F·g^(-1),并且能量密度和功率密度分别高达6.06 W·h·kg^(-1)和102.02 W·kg^(-1)。
The lignin was modified by hydrothermal activation/demethylation,and the modified lignin film was crosslinked with polyethylene glycol diglycidyl ether (PEGDE) and assembled into a supercapacitor.The structure and property of crosslinked modified lignin film was systematically studied,and the electrochemical performance of supercapacitor was analyzed.The supercapacitor exhibited the best performance fabricated with lignin film crosslinked by PEGDE at a content of 200%,mass specific capacitance,energy density and power density was 181.82 F·g^(-1),6.06 W·h·kgand 102.02 W·kg^(-1),respectively,at a current density of 0.2 A·g^(-1).
