The manufacturing data of lithium-ion batteries comprises the process parameters for each manufacturing step, the detection data collected at various stages of production, and the performance parameters of the battery [25, 26].
Fig. 1 shows the current mainstream manufacturing process of lithium-ion batteries, including three main parts: electrode manufacturing, cell assembly, and cell finishing .
The current research on manufacturing data for lithium-ion batteries is still limited, and there is an urgent need for production chains to utilize data to address existing pain points and issues.
In recent years, the rapid development of electric vehicles and electrochemical energy storage has brought about the large-scale application of lithium-ion batteries [, , ]. It is estimated that by 2030, the global demand for lithium-ion batteries will reach 9300 GWh .
With the rapid development of new energy vehicles and electrochemical energy storage, the demand for lithium-ion batteries has witnessed a significant surge. The expansion of the battery manufacturing scale necessitates an increased focus on manufacturing quality and efficiency.
The products produced during this time are sorted according to the severity of the error. In summary, the quality of the production of a lithium-ion battery cell is ensured by monitoring numerous parameters along the process chain.
