摘要
生物质硬碳具有比容量高、来源广泛、成本低廉等优势,是钠离子电池有潜力的负极材料。首次库仑效率(ICE)低,阻碍硬碳的商业化应用。综述生物质硬碳ICE提升的研究进展,从工艺参数优化、预处理、电解液体系调控和辅材优化等角度概括提升ICE的方法,如优化碳化温度、杂质含量以调控生物质硬碳的结构,优化电解质与电极组分等外部因素。
Biomass hard carbon is a potential anode material for sodium-ion battery due to its high specific capacity,wide source and low cost.The low initial Coulombic efficiency(ICE)of hard carbon hinders its commercial application.The research progress in biomass hard carbon ICE improvement is reviewed.The methods of improving ICE are summarized from aspects of process parameter optimization,pretreatment,electrolyte system regulation and auxiliary material optimization,such as optimizing carbonization temperature and impurity content to regulate the structure of biomass hard carbon,optimizing external factors such as electrolyte and electrode components.
