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.

Key words: Lithium-ion battery, electrode manufacturing, battery manufacturing process simulation, electrode microstructure, battery manufacturing equipment
