Phosphorus-Based Composite Anode Materials for Secondary Batteries

Secondary batteries play important roles in energy storage. Secondary batteries such as lithium/sodium-ion batteries are promising for portable electronic devices, electric vehicles and green energy storage. The research on novel electrode materials is important for rechargeable battery of next generation. Phosphorus is attractive as anode materials due to its high theoretical specific capacity and abundant resources. However, there are many unknown aspects of phosphorus materials, which hinders its development and application, especially in the field of energy storage. This paper focuses on the properties of all the allotropes of phosphorus, and briefly introduces the research advances of phosphorus anode in recent years, including preparation, the effects of matrix structure on electrochemical performances and on the mechanisms. Meanwhile, the paper prospects the development trend of phosphorus based composites, aiming at further application in secondary batteries.
