Phosphorus with advantages of super-high specific capacity and high-rate performance is considered as a promising anode material of ion batteries. In recent years, the studies of ion batteries have made a substantial progress and the related research system have been enriched, including the lithium-ion system and the sodium ion system. The current research of phosphorus-based anode materials is reviewed in detail with emphasis on research progress and electrochemical properties of elemental phosphorus, phosphorus/carbon composites, metal phosphide as anode materials. The characteristics and main problems of the phosphorus-based anode material are also analyzed in this paper. It proposes that amorphous coating and the crystallization process are the best way to solve the problem. Effect caused by electrolyte additive FEC on the electrochemical performance of phosphorus anode materials is briefly introduced. Finally, the development prospect of phosphorus anode materials in the future is also forecasted.
