How to make lithium-ion batteries for electric vehicles?

Dry a small amount of water. Sort the batteries according to their capacity. 06 Put the bare cells into the shell, spot welding, and vacuum drying. The bare cells are covered with packaging aluminum foil. The positive and negative materials are relatively sparse. Due to the process, the actual capacity of the battery is inconsistent, and the cells are completely sealed. 04 Cut According to the battery model, 07 injection will add the electrolyte to the battery cell. The battery can only be used as a power source after chemical conversion, and the positive and negative materials are compacted to a certain range. The production process of high-quality lithium-ion batteries for electric vehicles is very rigorous, because only in this way can its quality be guaranteed. The top and sides are thermally sealed to make the positive and negative pole piece rolls, respectively. Put a certain amount of pressure on the pole piece. To cut the positive and negative pole pieces into corresponding widths, 09 separate capacity In the manufacturing process, pass certain charge and discharge tests. 02 Coating: Intermittently and uniformly coat the slurry on the surface of the conveying current collector and dry, fully stir and disperse it. 05 Wind the small strips of positive and negative pole pieces and the separator film into a bare cell to make the internal positive and negative electrodes Material activation. 08 Formation The assembled battery is given a certain current. 10 Molding The shape of the battery cell is finally produced, so that the performance of the lithium-ion battery is guaranteed, and then it is baked at high vacuum and high temperature. Prepare a slurry, 03 cold press positive and negative electrode sheets after coating, mix the electrode active materials, binders, solvents, etc., in addition.
