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 .
2.1. State-of-the-Art Manufacturing Conventional processing of a lithium-ion battery cell consists of three steps: (1) electrode manufacturing, (2) cell assembly, and (3) cell finishing (formation) [8, 10].
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.
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.
However, there are still key obstacles that must be overcome in order to further improve the production technology of LIBs, such as reducing production energy consumption and the cost of raw materials, improving energy density, and increasing the lifespan of batteries .
