The invention discloses a preparation method of an anode material LiMxNiyMn2-x-yO4. The processes are as follows: (1) metering Li, Ni, Mn and salt doped with metal M according to the ratio of a chemical formula LiMxNiyMn2-x-yO4, putting the materials into a reactor, then adding water to form mixed solution, in the chemical formula, x is smaller than or equal to 0.3 and greater than or equal to 0, and y is smaller than or equal to 0.5 and greater than 0, metering fuel according to the molar ratio of the fuel to the Li being 0.5-2.5 to 1 and putting the fuel into a container; then adding water to form fuel solution; adding the fuel solution into the mixed solution; agitating for 5-10 hours at a normal pressure at 50-80 DEG C and heating to 90-95 DEG C to agitate until foaming, or directly agitating until foaming at the normal pressure at 80-95 DEG C to obtain precursor slurry; (2) inputting the precursor slurry into a fuel tower, atomizing the precursor slurry through high-pressure air, and burning the atomized precursor slurry under the action of the fuel and compressed air, wherein the combustion product is precursor powder; (3) carrying out tempering on the precursor powder for 1-10 hours at 600-1000 DEG C at the normal pressure, and then naturally cooling the precursor powder to a room temperature to obtain the LiMxNiyMn2-x-yO4.

The invention discloses a preparation method of a magnetic carbon material and belongs to the technical field of carbon materials. The problems that wastewater is produced in a conventional process ofpreparing the magnetic carbon material by taking ferroferric oxide as a magnetic component, the preparation process is complicated and equipment is expensive can be solved. The preparation method specifically comprises the following steps: taking ferrocene and red phosphorus as raw materials, uniformly mixing the two materials according to a feed mass ratio of (0.5-3):1, and heating in a closed reactor with oxygen content of 5-25%, wherein the temperature rise mechanism comprises the following steps: raising the temperature to 400-500 DEG C at a rate of 1-5 DEG C per minute, maintaining the constant temperature for 1-5 hours, and naturally cooling to a room temperature; opening the reactor to take out the reaction product, heating under the temperature condition of 40-80 DEG C, initiatingcombustion, and collecting the obtained black fluffy combustion product, namely the magnetic carbon material. The preparation method of the magnetic carbon material disclosed by the invention has theadvantages of being simple and reliable in process route, capable of realizing large-scale preparation and the like.
