This Chapter describes battery cell production processes as well as battery module and battery pack assembly processes. Lithium-ion cell production can be divided into three main process steps: forming, aging, and testing. Cell design is the number one criterion when setting up a cell production facility.
Sub-process steps in battery cell production involve a great number of companies that have the know-how for specific production steps and offer various production technologies for these steps. However, these companies have very little know-how regarding the production steps before or after their particular specialism.
The first stage in battery manufacturing is the fabrication of positive and negative electrodes. The main processes involved are: mixing, coating, calendering, slitting, electrode making (including die cutting and tab welding). The equipment used in this stage are: mixer, coating machine, roller press, slitting machine, electrode making machine.
The formation process involves the battery's initial charging and discharging cycles. This step helps form the solid electrolyte interphase (SEI) layer, which is crucial for battery stability and longevity. During formation, carefully monitor the battery's electrochemical properties to meet the required specifications. 6.2 Conditioning
