Abstract：Lithium-ion batteries, with their numerous outstanding properties, have found extensive application in diverse domains. Nowadays, hard carbon is deemed as one of the most promising anode materials for secondary ion batteries, owing to its high capacity, low potential, extensive availability and eco-friendliness. Among various carbon source materials, biomass materials have garnered significant attention on account of their plentiful resources and low expenditure. This paper summarizes the relevant research results at home and abroad on the preparation of hard carbon electrode materials from biomass waste in recent years. By comparing different types of biomass hard carbon electrode materials and their preparation methods, the opportunities and challenges faced in the current research of biomass hard carbon materials are sorted out. This paper has certain reference value for obtaining hard carbon anode materials with better performance, lower cost and wider application by using biomass materials.
