摘要

无溶剂电极制造(SEF)是电池制造领域的革命性进步,为传统的基于浆料的加工提供了一种引人注目的无溶剂替代方案。SEF具有显著的优势,包括消除有毒溶剂、溶剂回收步骤、降低能耗、降低环境影响、降低总体成本,以及克服在制造较厚电极过程中遇到的粘合剂迁移问题。然而,SEF的实际应用必须克服关键挑战,例如实现均匀的颗粒分布,确保强电极凝聚力和附着力,以及扩大规模以满足工业生产需求。本文对干电极制造技术的现状进行了全面的评估,包括干压、喷雾干燥沉积和3D打印等先进技术。除了对优化电池性能至关重要的机械和电化学因素外,材料的基本化学也得到了详细阐述,并明确了锂离子电池(lib)从实验室到制造阶段的重点。此外,文章强调了最近的重大进展,确定了关键的技术障碍,并概述了在可持续能源存储领域释放干电极制造的全部潜力所必需的必要研究方向。

Solvent-free electrode fabrication (SEF) is a revolutionary advancement in the field of battery manufacturing, providing a compelling, solvent-free alternative to conventional slurry-based processing. SEF offers significant benefits, including reduced energy consumption resulting from the elimination of toxic solvents, solvent recovery steps, a lower environmental impact, overall cost reduction, and overcoming of binder migration, encountered during the fabrication of thicker electrodes. However, the practical application of SEF must overcome key challenges, such as achieving uniform particle distribution, ensuring strong electrode cohesion and adhesion, and scaling up to meet industrial production demands. This review provides a comprehensive assessment of the current landscape in dry electrode fabrication technologies, featuring advanced techniques such as dry pressing, spray dry deposition, and 3D printing. The fundamental chemistry of materials in addition to the mechanical, and electrochemical factors critical for optimizing battery performance is elaborated with a clear focus on lithium-ion batteries (LIBs) from lab to manufacturing stage. Moreover, the article highlights significant recent advancements, identifies critical technical barriers, and outlines imperative research directions necessary to unleash the full potential of dry electrode manufacturing in the realm of sustainable energy storage.
