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].
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.
Fig. 1 shows the current mainstream manufacturing process of lithium-ion batteries, including three main parts: electrode manufacturing, cell assembly, and cell finishing .
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.
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.
Production chain for lithium-ion batteries Lithium-ion cells are galvanic elements that convert electrical energy into chemical energy and vice versa . Hence, they are able to store and release large amounts of energy, e.g. electricity generated by solar or wind energy used to power an electric vehicle.
