Abstract: The development of electrode materials is one of the key factors in the application of sodium ion batteries. Carbon-based anode materials have attracted the attention of experts and scholars at home and abroad because of their advantages of rich raw materials,low cost,high reversible capacity and good rate performance. In this paper,the recent research progress of the carbon-based anode materials for sodium ion batteries have been briefly reviewed,and the classification and doping modification of graphite and non-graphite carbon-based anode materials are described in detail. Graphite-based materials are graphite and graphene,while non-graphite-based materials are soft carbon and hard carbon and element doping modification is mainly N-and S-based. The electrochemical properties and the possible mechanism of the sodium storage process are discussed in detail as well. The future advances of carbon-based anode materials should mainly focus on improving the low efficiency of coulomb,the phenomenon of severe voltage hysteresis and poor cycle stability. The future modification direction is to increase the carbon layer spacing,reduce the structure into nanoscale and optimize the preparation process to ensure the high cyclical stability and excellent rate performance.

Key words: sodium ion battery, carbon-based anode materials, doping modification, electrochemical performance, charge/discharge mechanism
