摘要
A preparation method of olivine Li1+xFe1+yPO4 is disclosed, wherein −0.2≦x≦0.2 and −0.2≦y≦0.2, which includes the following steps: (A) adding iron powder, lithium salt, and phosphate into an acid solution to form a mixture, wherein the molar ratio of Li+:Fe2+:PO43− is 1+x:1+y:y; (B) stirring the mixture; (C) drying the mixture to obtain solid precursor powder; and (D) heating the precursor solid powder at a temperature over 500° C. to form olivine structured powders.
