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).
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 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.
In this regard, novel material design, together with next-generation manufacturing technologies, including solvent-free manufacturing, will help in making the process cost-effective and environmentally friendly. Technology is evolving towards Industry 4.0; therefore, it is inevitable for battery manufacturers to get their share.
The benefit of the process is that typical lithium-ion battery manufacturing speed (target: 80 m/min) can be achieved, and the amount of lithium deposited can be well controlled. Additionally, as the lithium powder is stabilized via a slurry, its reactivity is reduced.
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).
