The invention belongs to the technical field of lithium supplementing materials of lithium ion batteries, and particularly relates to a preparation method of lithium ferrite. By adopting a solvent method, an iron source, a lithium source and organic acid are mixed in a water-containing solvent to obtain ferric hydroxide colloid with smaller particle size. Meanwhile, the organic acid reacts with alithium source to generate a lithium salt, and the lithium salt and the ferric hydroxide colloid can be attached to the surface of the ferric hydroxide colloid after being heated to form a precursor solution with higher activity. And after the obtained precursor solution is dried, lithium ferrite with relatively high purity can be obtained only by once sintering, so the problems of repeated sintering, insufficient sintering reaction, long sintering time and high impurity content of a conventional solid-phase method are solved.
