摘要:

锂离子电池的综合性能不仅取决于材料和结构的创新,还与制造工艺及相关设备技术的进步息息相关。目前电池制造厂商针对不同体系的电池工艺开发多采用穷举法进行实验试错,在工艺仿真技术方面还存在较大的发展空间。面向电池高质量制造发展和数智化升级的行业发展趋势,本文结合宏观电池制造设备和微观电池电极结构两个角度,对电池制造工艺仿真研究现状进行了系统总结,分析了各工序工艺仿真技术机理研究、结构发展及应用前景,并进一步指出当前研究的不足及未来的发展趋势,旨在为优化锂离子电池的制造流程和提高其综合性能提供理论参考。

Abstract:

The overall performance of lithium-ion batteries not only depends on the innovation of materials and structures, but also is closely related to the progress of manufacturing processes and related equipment technologies. At present, battery manufacturers use the exhaustive method of experimental trial and error to develop battery processes for various systems, and there is still much room for development in process simulation technology. Facing the development trend of high-quality battery manufacturing and digital intelligence upgrading, this paper systematically summarizes the current situation of battery manufacturing process simulation research from the two perspectives of macro battery manufacturing equipment and micro battery electrode structure, analyzes the mechanism research, structure development and application prospect of each process simulation technology, and further points out the shortcomings of current research and future development trend, so as to provide theoretical references for optimizing the manufacturing process of lithium-ion batteries and improving their overall performance.
