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.
This process is mainly used in the production of square and cylindrical lithium-ion batteries. Winding machines can be further divided into square winding machines and cylindrical winding machines, which are used for the production of square and cylindrical lithium-ion batteries, respectively.
Lithium battery manufacturing equipment encompasses a wide range of specialized machinery designed to process and assemble various components, including electrode materials, separator materials, and electrolytes, in a carefully controlled sequence.
Figure 1 introduces the current state-of-the-art battery manufacturing process, which includes three major parts: electrode preparation, cell assembly, and battery electrochemistry activation. First, the active material (AM), conductive additive, and binder are mixed to form a uniform slurry with the solvent.
