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
