摘　　要：生物质材料是由生命体衍生得到的材料,具有可再生、可降解的特征,而且其结构中富含多种活性基团,能与电极活性材料产生氢键、离子-偶极和化学键等强相互作用。传统的油溶性黏结剂因活性基团缺乏、使用有机溶剂等特点,不利于电池综合性能和绿色发展,而采用生物质黏结剂是一种实现高循环性能、抗容量衰减的有效手段之一。该文综述了生物质黏结剂的分类及特点、与活性材料之间的作用机理,重点介绍和总结了生物质黏结剂在锂离子电池和钠离子电池中的应用,并展望生物质黏结剂在电化学领域的发展方向。未来的研究仍应集中于对天然生物质进行改性,使其兼具良好的黏附性、分散性、导电性和自愈性,以便更好地利用生物质材料的结构特性和功能特性。Biomass materials are derived from living organisms and possess renewable and degradable characteristics,which contain various active groups that can interact strongly with electrode active materials through hydrogen bonding,ion-dipole interactions,and chemical bonding.Traditional oil-soluble binders,lacking active groups and relying on organic solvents,are not conducive to achieving comprehensive battery performance and green development.On the other hand,the use of biomass binders proves to be an effective approach in achieving high cycling performance and resistance to capacity degradation.Herein,the characteristics of biomass binders and the mechanisms of their interaction with active materials were reviewed.And the application of biomass binders in lithium-ion and sodium-ion batteries were emphatically introduced and summarized.The future development direction of biomass binders in the field of electrochemistry was also discussed.It was suggested that future research should focus on natural biomass modification to achieve properties such as good adhesion,dispersion,electrical conductivity,and self-healing capabilities to enable better utilization of the structural and functional properties of biomass materials.
