The development of cheap, efficient and stable carbon anode materials for sodium ion batteries is one of the important researchdirections in the field of electrochemical energy storage. Sulfur doped needle coke based polyporous carbon (S-NC) was prepared by atwo-step process of mechanical ball milling combined with sulfur doping using needle coke as carbon source and sublimed sulfur as sulfursource, and was applied to the negative electrode of sodium ion batteries. The results of SEM, TEM and XPS indicate that the sulfur doping strategy can effectively reduce the particle size of carbon materials, increase the layer spacing of carbon materials, and increase thedefect density of carbon skeleton. The results of nitrogen adsorption and desorption test show that compared with undoped carbon, the porevolume of S-NC is significantly increased, and it is rich in mesoporous. The electrochemical test results show that the prepared sulfurdoped carbon (S-NC-600) exhibits excellent sodium storage properties when the doping temperature is 600 ℃ . When the current densityis 0.05 A/ g, the specific capacity of S-NC-600 is 487.3 mAh/ g. At 2 A/ g high current density, the specific capacity is 275.5 mAh/ g,and after 1 000 cycles of charge and discharge, the capacity retention rate is 90.7%, showing good rate performance and cycle stability,which can provide theoretical support for the preparation of carbon anode for high efficiency sodium-ion batteries.
