Abstract:

With the rapid development of portable electronic products,electric vehicles and energy storage,the demand for high energy density batteries is more and more urgent.Cathode materials are the main limits for the energy-density of batteries.Transition metal fluoride phosphates(A2MPO4F;A=Li,Na;M=Mn,Fe,Co,Ni) is a type of competitive cathode materials with high-capacity(~300 mA·h/g) and high energy density(>1 000 W·h/kg).The research progress related to the A2MPO4F cathode materials on the structures,synthesis methods and improving techniques for electrochemical performance were mainly introduced.The key challenges of A2MPO4F cathode materials faced,especially the difficulties in realizing the two electron reaction,were discussed.Finally,the future trends and perspectives for performance enhancement were prospected.

Key words: lithium-ion batteries, sodium-ion batteries, cathode materials, transition metal fluoride phosphates
