One kind of Cu 2 + , Co 2 + , Zr 4 + , Ag + Composite doped with ferric fluoride The positive electrode material and preparation method

One kind of Cu2 +, Co2 +, Zr4 +, Ag + and a positive electrode material modified iron fluoride doping method of preparation, the method copper, cobalt salt, a zirconium salt, silver salt with a synthetic raw material for some time after the heat treatment and milling in a high energy ball mill FeF3 obtain a positive electrode material. Cu2 + partially occupied by Fe ion coordinated FeF3, contribute to enhancing its discharge potential, increase the energy density; Co2 + doping through, help to improve the lithium ion conductivity material; Zr4 + doped by high, increase in the ratio of the material capacity while fine-tune the size of lithium ion channel; doped by Ag +, conversion decreases activation energy charging; this helps improve the rate characteristics and the energy density, thereby improving the overall electrochemical properties of the material.
