Sodium-ion batteries(SIBs)are the most promising new system for large-scale energy storage applications.Finding low cost and high-performance anode materials has become the key to the development of sodium ion batteries.Hard carbon(HC)is one of the most promising anode materials for industrialization.In view of the shortcomings of HC materials,such as low first coulombic efficiency(ICE),poor magnification performance and poor cycling stability,this paper reviews the strategies to improve the sodium storage performance of HC anode materials based on the microstructure characteristics and sodium storage mechanism of HC materials,including carbonation process regulation,heteroatomic doping,surface modification,electrolyte optimization etc.The design thought of hard carbon materials is summarized at last.
