The invention relates to a zinc-site sodium-copper co-doped synergistic nitrogen-sulfur doped carbon-coated modified zinc titanate negative electrode material and a preparation method and applicationthereof. The preparation method comprises the following steps: (1) preparing a nitrogen doped carbon material; (2) dissolving a zinc source, a sodium source and a copper source to obtain a solution A;dissolving a titanium source to obtain a solution B; mixing the two solutions to obtain a solution C; (3) adding the nitrogen doped carbon material into the solvent to obtain a solution D; and (4) mixing the solution C and the solution D, stirring, centrifugal drying, mixing the obtained solid powder with a sulfur source and sintering so as to obtain the negative electrode material. The preparednegative electrode material has uniform particle size, stable and compact structure, high conductivity and good cycle stability. The negative electrode plate and the lithium ion battery prepared by the negative electrode material have good cycle performance and long service life and meet the requirements in practical application.
