The manufacturing and assembly of components within cells have a direct impact on the sample performance. Conventional processes restrict the shapes, dimensions, and structures of the commercially available batteries. 3D printing, a novel manufacturing process for precision and practicality, is expected to revolutionize the lithium battery industry owing to its advantages of customization, mechanization, and intelligence. This technique can be used to effectively construct intricate 3D structures that enhance the designability, integrity, and electrochemical performance of both liquid‐ and solid‐state lithium batteries. In this study, an overview of the development of 3D printing technologies is provided and their suitability for comparison with conventional printing processes is assessed. Various 3D printing technologies applicable to lithium‐ion batteries have been systematically introduced, especially more practical composite printing technologies. The practicality, limitations, and optimization of 3D printing are discussed dialectically for various battery modules, including electrodes, electrolytes, and functional architectures. In addition, all‐printed batteries are emphatically introduced. Finally, the prospects and challenges of 3D printing in the battery industry are evaluated. As an innovative technology, 3D printing can construct customized 3D architectures. Precision structural design helps to address the current challenges faced by different types of lithium batteries, and thus 3D printing has the potential to transform the battery manufacturing process. Its feasibility and practicality in the lithium battery manufacturing industry are the subjects of this review.
