The manufacturing process for the Li-Ion battery can be divided roughly into the five major processes: 1. Mixing, kneading, coating, pressing, and slitting processes of the positive electrode and negative electrode materials. 2. Winding process of the positive electrode, negative electrode, and separator.
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.
In addition, the transferability of competencies from the production of lithium-ion battery cells is discussed. The publication “Battery Module and Pack Assembly Process” provides a comprehensive process overview for the production of battery modules and packs.
In the formation process (which has already taken place for the pouch), the cell is charged for the first time, which virtually activates the battery cell. The charging and discharging of the battery cell must be carried out in a very controlled manner so that the SEI (Solid Electrolyte Interface) forms in a thin and homogeneous layer on the anode.
The Li-Ion battery is manufactured by the following process: coating the positive and the negative electrode-active materials on thin metal foils, winding them with a separator between them, inserting the wound electrodes into a battery case, filling with electrolyte, and then sealing the battery case.
