The invention provides a lithium battery positive electrode precursor and a spray pyrolysis rapid synthesis method and application thereof, and the spray pyrolysis rapid synthesis method comprises the following steps: mixing a metal source solution and an additive to obtain a mixed solution; the additive comprises organic acid and organic alcohol; and carrying out spray pyrolysis on the mixed solution to obtain the lithium battery positive electrode precursor. According to the spray pyrolysis rapid synthesis method, ester substances are generated in situ through the organic acid and the organic alcohol during spray pyrolysis, the particle size of particles is controlled, particle aggregation is prevented, and the particle sphericity, the particle size distribution uniformity and the like of the lithium battery positive electrode precursor are improved, so that the multiplying power, the cycle performance and the like of the battery are improved. 本发明提供了一种锂电正极前驱体及其喷雾热解快速合成方法与应用，所述喷雾热解快速合成方法包括如下步骤：将金属源溶液和添加剂进行混合
