NOVELTY - A lithium salt, iron salt, phosphate, and doped metal are mixed, to obtain powder to which dispersant is added, mechanical activation is carried out and dried. The dried powder is roasted, to obtain precursor powder of doped lithium-iron-phosphate to which carbon source material is added, pulverized and dried. The dried powder is put into tube-shaped furnace, roasted under nitrogen atmosphere and cooled to room temperature, to obtain anode material which is pulverized and screened, to obtain metal doped carbon-coated lithium iron phosphate anode material.    USE - Preparation of metal doped carbon-coated lithium-iron-phosphate anode material used for lithium-ion battery.    ADVANTAGE - The metal doped carbon-coated lithium-iron-phosphate anode material is economical. The method provides anode material simply and rapidly without pollution.    DETAILED DESCRIPTION - A lithium salt, iron salt, phosphate, and doped metal (M) in mol ratio of 1:(1-x):x:1, where x=0.005-0.04 are mixed, to obtain powder. To the obtained powder de-ionized water or other dispersant is added and is taken in container which is fixed in ultrasonic equipment. Mechanical activation is carried out at a mixing speed of 100-500 rate/minute and at a frequency of 20-300 kHz for 2-10 hours and dried below 100 degrees C. The dried powder is taken in a tube-type furnace, roasted for at 350-450 degrees C for 2-10 hours under nitrogen atmosphere, to obtain precursor powder of doped lithium-iron-phosphate. To the obtained precursor powder carbon source material containing carbon (5-20 wt.%) is added, pulverized for 2-10 hours and dried below 100 degrees C. The dried powder is put into tube-shaped furnace, roasted at 550-700 degrees C for 8-16 hours under nitrogen atmosphere and cooled to room temperature, to obtain anode material. The obtained material is subjected to grinding and screening, to obtain metal doped carbon-coated lithium-iron-phosphate anode material of formula (LiFe1-xMxPO4/C). The lithium salts are lithium carbonate, lithium phosphate, lithium hydroxide and lithium nitrate, preferably lithium carbonate. The iron salts are ferrous oxalate and ferrous acetate, preferably ferrous oxalate. The phosphate is diammonium phosphate and monoammonium phosphate, preferably diammonium phosphate. The doped metal is magnesium acetate, magnesium oxide, chromic oxide, N-butanol tetrabutyl, titanium oxide, praseodymium oxide, chromium acetate and cerium oxide. The dispersant is de-ionized water, absolute ethanol, distilled water and acetone, preferably de-ionized water. The carbon source material is acetylene black, graphite, sucrose, glucose, epoxy resin or other organic material capable of being decomposed into carbon, preferably acetylene black.
