The rapid design of advanced materials depends on synthesis parameters and design. A wide range of materials can be synthesized using precursor reactions based on chelated gel and organic polymeric gel pathways. The desire to develop high-performance lithium-ion rechargeable batteries has motivated decades of research on the synthesis of battery active material particles with precise control of composition, phase-purity, and morphology. Among the most common methods reported in the literature to prepare precursors for lithium-ion battery active materials, sol-gel is characterized by simplicity, homogeneous mixing, and tuning of the particle shape. The chelate gel and organic polymeric gel precursor-based sol-gel method is efficient to promote desirable reaction conditions. Both precursor routes are commonly used to synthesize lithium-ion battery cathode active materials from raw materials such as inorganic salts in aqueous solutions or organic solvents. The purpose of this review is to discuss synthesis procedure and summarize the progress that has been made in producing crystalline particles of tunable and complex morphologies by sol-gel synthesis that can be used as active materials for lithium-ion batteries.
先进材料的快速设计取决于合成参数和设计。基于螯合凝胶和有机聚合物凝胶途径的前驱体反应可以合成多种材料。开发高性能锂离子可充电电池的需求推动了数十年来对电池活性材料颗粒合成的研究，以精确控制其组成、相纯度和形态。在文献报道的制备锂离子电池活性材料前驱体的最常见方法中，溶胶-凝胶法具有操作简单、混合均匀以及可调节颗粒形状的特点。基于螯合凝胶和有机聚合物凝胶前驱体的溶胶-凝胶法能够有效地促进理想的反应条件。这两种前驱体路线通常用于从水溶液或有机溶剂中的无机盐等原料合成锂离子电池正极活性材料。本综述的目的是讨论合成过程，并总结通过溶胶-凝胶合成制备具有可调谐和复杂形态的晶体颗粒（可作为锂离子电池活性材料）所取得的进展。
