摘要:木质素储量丰富、含碳量高、具有大量苯环结构，是新型储能设备超级电容器电极材料的潜在原料。木质素含有大量的醚键（占总连接键50%以上），在炭化时容易形成多酚羟基型单元，该结构在充放电过程中能够有效增强赝电容，进而提高超级电容器电极材料的电化学性能。本文综述了木质素复合电极材料、木质素基活性炭材料、木质素模板化碳材料的应用，总结了木质素基超级电容器现阶段的发展方向，展望了木质素基超级电容器电极材料的可应用领域。
Abstract:Lignin is rich in reserves with high carbon content and a large number of benzene structures， which is a potential raw material of electrode material for new energy storage devices supercapacitors. Lignin contains a large number of ether bonds， which account for more than 50% of the total linkage bonds， and easily forms polyphenolic hydroxyl units during carbonization. This structure can effectively enhance the pseudocapacitance during the charging and discharging process， which enables the electrochemical performance of electrode materials in supercapacitors to be improved. The applications of lignin composite electrode materials， lignin activated carbon materials and lignin template carbon materials were reviewed in this paper. The development direction of lignin-based supercapacitors was summarized and prospected. The application fields of ligin-based electrode materials for supercapacitors were prospected.
