The invention relates to a preparation method for synthesizing a lithium battery cathode material through a solvent-free solid-phase method. The method comprises the following steps that solid-state high-hydrocarbon fatty acid and / or solid-state high-hydrocarbon fatty acid salt and flake graphite are mixed evenly to obtain a multifunctional auxiliary; the multifunctional auxiliary and raw materials are added into mixing equipment together to prepare a precursor; high-temperature sintering is performed on the precursor after heat treatment is performed on the precursor, and then the lithium battery cathode material is obtained. According to the method, by adding the multifunctional auxiliary of which the main components comprise the solid-state high-hydrocarbon fatty acid and / or the solid-state high-hydrocarbon fatty acid salt in the mixing stage, the problem that diversified scattering of the raw materials is difficult is solved through the lubrication action of high-hydrocarbon fatty acid radicals, metal ions carried by the high-hydrocarbon fatty acid salt can also be evenly dispersed in the precursor in the mixing process to serve as a doping ion source in body doping, and the high-hydrocarbon fatty acid radicals can be decomposed at high temperature to generate gas, so that the fluffy degree of the precursor is increased and hardening is relieved; therefore, generation of oxygen vacancy is reduced in the sintering process, and the prepared lithium battery cathode material has the advantages of being few in defect, excellent in electrochemical performance and the like.
