Abstract:

As a novel anode material for lithium-ion batteries, red phosphorus shows a high specific capacity and rate capability in lithium storage and has attracted increasing attention in recent years. In this paper, the research progress on red phosphorus-based anode materials is briefly reviewed, particularly the crucial parameters involved in practical battery applications (e.g., binders, electrochemical characteristics of the electrode, and expansion and contraction rates of the electrode). It is also compared with other new anode materials. The practicability of the red phosphorus anode is emphatically analyzed. The advantages and disadvantages of the red phosphorus anode and the key problems needed to be solved before application are discussed.

Key words: lithium ion battery, red phosphorus composite anode, research progress, practical application
