The Progress and Future Prospects of Lithium Iron Phosphate Cathode Materials

Abstract

Generally, the lithium iron phosphate (LFP) has been regarded as a potential substitution for LiCoO2 as the cathode material for its properties of low cost, small toxicity, high security and long life. However, it still has many disadvantages like poor electrical conductivity and low ion mobility. This article will focus on the preparation of lithium iron phosphate cathode materials successfully at the present stage, introduce its development status, and predict the future development direction of such materials. Analysis shows that with significant modification and process, both performance and cost of this material will be significantly improved. These results show some potential ways for the further wide application of LFP positive electrode.
