How are high-quality lithium batteries for electric vehicles made?

After years of development, the lithium battery industry has formed a complete industrial chain with a high degree of specialization and engineering. With the support of national policies and the introduction of the new national standard for electric vehicles, lithium batteries will be the first choice for electric travel tools in the future. So, how are high-quality lithium batteries for electric vehicles made? Master tell you! The first step: the ingredients are mixed with high-vacuum and fully automatic materials for 10 hours to disperse the materials needed by the lithium battery evenly, and improve the consistency and comprehensive performance of the battery. Why do you want to do this? Because ingredients are the core area of u200bu200blithium battery production, poor ingredients directly affect the performance of lithium batteries. The second step: the coating adopts an automatic feeding system, an automatic knife adjustment system, and an online thickness measurement system to coat the positive and negative plates evenly. Why do you want to do this? Because coating is the basis of lithium battery production, coating determines the consistency of the battery. The third step: After coating the positive and negative electrodes of the roll, the positive and negative materials are relatively loose, and a certain pressure must be applied to the pole pieces to compact the positive and negative materials to a certain range. The fourth step: according to the battery model, the positive and negative plates should be cut into the required width. Such as 18650 lithium battery, the width of the pole piece is within 56-58mm. Step 5: Using a fully automatic tablet machine for film making and winding, weld the positive and negative lugs to the positive and negative plates. A fully automatic winding machine is used to wind the positive and negative plates and the separator into a cylindrical shape. Step 6: Put the bottom rolling groove and vacuum drying core into the steel shell, automatically weld the negative lug, and automatically roll the groove. In addition, after high-vacuum and high-temperature baking, a small amount of moisture is dried, so that the performance of the lithium battery can be guaranteed.
