Synthesis method of discontinuous vapor deposition carbon-coated lithium manganese iron phosphate material

The invention relates to a synthetic method of a discontinuous vapor deposition carbon-coated lithium manganese iron phosphate material, and belongs to the technical field of lithium battery preparation. The invention discloses a synthetic method of a discontinuous vapor deposition carbon-coated lithium manganese iron phosphate material. The synthetic method comprises the following steps: (1) preparing a precursor; (2) pre-sintering organic carbon coating; (3) performing vapor deposition carbon coating on the rotary kiln; and (4) crushing and sieving. The synthesis method of the discontinuous vapor deposition carbon-coated lithium manganese iron phosphate material disclosed by the invention comprises the following steps: selecting raw materials to prepare a precursor, then carrying out two-stage sintering of pre-sintering organic carbon coating and rotary kiln vapor deposition carbon coating on the precursor, and then crushing and sieving to obtain the discontinuous vapor deposition carbon-coated lithium mang
