木质素及其衍生碳在电化学储能材料中的应用

Application of Lignin and Lignin Derived Carbon in Electrochemical Energy Storage Materials

木质素作为存有量巨大的可再生天然碳基有机聚合物,具有特殊的天然纤维结构及丰富的官能团等特性。将不同的木质素进行热处理碳化及激活后,可转变为高附加值的碳材料,如多孔碳、碳纳米纤维、活性碳等。本文从木质素复合材料及木质素衍生碳两个方面进行了介绍,对造纸工业副产品木质素在电化学储能材料中的最新应用研究进行了综述。结合目前双碳背景,木质素及其衍生碳的研究对造纸行业副产品的综合利用具有极大的意义,为造纸工业的清洁化生产提供了新的思路。

As a renewable natural carbon based organic polymer with huge reserves,lignin has unique natural fiber structure and rich functional groups.After heat treatment,carbonization and activation,different lignin will be transformed into high value-added carbon materials,such as porous carbon,carbon nanofibers,activated carbon,etc.The lignin composite materials and lignin derived carbon were introduced,and the application research of by-product lignin in electrochemical energy storage materials in the papermaking industry in recent years were reviewed in this paper.Under the current dual carbon background,the research on lignin and lignin derived carbon has great significance for the comprehensive utilization of by-product in the papermaking industry,providing new ideas for the clean production of the paper industry.
