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].
Production steps in lithium-ion battery cell manufacturing summarizing electrode manufacturing, cell assembly and cell finishing (formation) based on prismatic cell format. Electrode manufacturing starts with the reception of the materials in a dry room (environment with controlled humidity, temperature, and pressure).
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].
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.
Manufacturing of Lithium-Ion Battery Cells LIBs are electrochemical cells that convert chemical energy into electrical energy (and vice versa). They consist of negative and positive electrodes (anode and cathode, respectively), both of which are surrounded by the electrolyte and separated by a permeable polyolefin membrane (separator).
Battery manufacturing generates data of multiple types and dimensions from front-end electrode manufacturing to mid-section cell assembly, and finally to back-end cell finishing. Most of these data is utilized for performance prediction, process optimization, and defect detection [33, , , ].
