[Abstract]:Carbon anode material is the best cathode material for lithium ion battery so far. By designing the microstructure of carbon materials, the energy density, power density and cycle life of lithium-ion batteries can be improved significantly, which can meet the requirements of new energy vehicles for power batteries. Compared with traditional graphite anode materials, hard carbon has the advantages of high lithium intercalation capacity, good rate performance and long cycle life. By changing the carbon source and optimizing the preparation process, researchers have prepared a series of hard carbon materials with unique structure and excellent properties. Based on the latest research progress of hard carbon based lithium ion battery anode materials, the research work of preparing hard carbon materials from different carbon sources is summarized, and the influence of hard carbon microstructure on the lithium intercalation properties of hard carbon materials is briefly analyzed. Finally, the paper summarizes and points out the problems to be solved in this field and the development direction in the future.
