Analysis of Electro-chemical Properties of LiMn0.6Fe0.4PO4 Coated with Hydroxyl Cobalt
In order to improve the cycling and rate fast charging performance of Lithium-ion batteries,LiMn0.6Fe0.4PO4 needs to be modified.In this paper,hydroxylated cobalt oxide is coated and sintered to form a cobalt compound coating with trivalent Co on the surface.The high valence Co compound has a high lithium-ion diffu-sion coefficient and electronic conductivity,which can significantly improve the lithium-ion diffusion rate and electro-chemical reaction rate at the LiMn0.6Fe0.4PO4 interface,and improve the cycling and low-temperature per-formance of LiMn0.6Fe0.4PO4.
