Disclosed is a preparation method for a high capacity lithium-ion battery negative electrode material. The preparation method for the high capacity lithium-ion battery negative electrode material, in which raw materials are proportioned according to parts by weight, comprises the following process steps: (1) titanium dioxide, lithium carbonate, tin nanoparticles, and a resin are mixed into a uniform slurry; (2) a precursor powder is produced via spray drying; and, (3) under the protection of a noble gas, the powder produced in step (2) undergoes a high temperature treatment and is then cooled and sieved to produce the high capacity lithium-ion battery negative electrode material. |
