Through the establishment of appropriate numerical models, simulation analysis of the respective link in the manufacturing process can effectively predict and optimize the process flow, reduce the experimental cost, and improve the production efficiency and overall performance of the battery .
It is one of the hot research topics to use the systematic simulation model of lithium-ion battery manufacturing process to guide industrial practice, reduce the cost of the current experiment exhaustive trial and error, and then optimize the electrode structure and process design of batteries in different systems.
Key challenges include the complexity of both the product and process, the novelty of battery production in regions like Europe and the U.S., the scale and automation level of facilities, the availability of skilled workers. Additionally, cultural, and linguistic barriers can further complicate operations.
Due to the requirement of high quality development and the digital intelligent upgrade in the battery manufacturing industry, digital simulation and digital twin technology would be employed to develop and optimize the battery manufacturing process.
Nevertheless, mixing and coating may be the processes of highest importance for quality. In general terms: the key to profitable battery cell produc- tion is to optimize throughput (the number of cells produced per unit of time) and yield (the percentage of cells without defects).
According to the existing research, each manufacturing process will affect the electrode microstructure to varying degrees and further affect the electrochemical performance of the battery, and the performance and precision of the equipment related to each manufacturing process also play a decisive role in the evaluation index of each process.
