Lithium-based systems opened a new era for high-energy and high-power batteries and more and more replace other battery technologies such as lead–acid and nickel-based systems. From the late 1960s, many battery technologies were explored and emerged because conventional aqueous batteries fail to satisfy the booming demands for portable
The production of the lithium-ion battery cell consists of three main process steps: electrode manufacturing, cell assembly and cell finishing. Electrode production and cell finishing are largely independent of the cell type, while within cell assembly a distinction must be made between pouch cells, cylindrical cells and prismatic cells.

The production process of a lithium-ion battery cell consists of three critical stages: electrode manufacturing, cell assembly, and cell finishing. The first stage is electrode manufacturing, which involves mixing, coating, calendering, slitting, and electrode making processes.
In the next section, we will delve deeper into the battery cell assembly processes. Battery cell assembly involves combining raw materials, creating anode and cathode sheets, joining them with a separator layer, and then placing them into a containment case and filling with electrolyte.
To complete the formation process, 3-5 cycles at 0.1 C at room temperature and 3-5 cycles at higher C-rate at higher temperature are required to control the thickness of the SEI layer. This takes several days and means the bottleneck in the battery formation process and the battery production itself.
After the battery module is assembled, it needs to be placed into the battery tray. As this tray is a key structural component of the vehicle as well as integral in protecting the battery cells, it needs to be of the highest strength and stability.
