摘要
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. ? 2024 Fine Chemicals.
