<p>The invention discloses a method for synthesizing lithium iron phosphate which is a lithium-ion battery anode material, comprising the process of roasting the reaction raw materials including lithium salt, ferrous salt and phosphorus compound in a vacuum environment. The method adopts the vacuum sintering method to synthesize lithium iron phosphate, the lithium-ion battery anode material, and the synthesizing process requires no protection of inert gases, so as to reduce the manufacturing costs, simplify the processes and achieve lithium iron phosphate with excellent performance. For the process of synthesizing the precursor organic matter which is used in the raw materials, the carbon which is produced by the decomposition of precursor organic matters at high temperatures will not be consumed when adopting the method and the final carbon content in the synthetic product can be precisely controlled.</p> |
