The tutorial for making your own lithium battery is as follows:
Step One: Ingredients. High vacuum stirs materials fully automatically for 10 hours to evenly disperse materials needed for lithium batteries, improving overall battery consistency and performance. Why are you doing this? Since ingredients are the core of lithium battery production, poor quality ingredients directly affect the performance of lithium batteries.
Step 2: Coating. It adopts automatic feeding system, automatic knife adjustment system and online side thickness system to evenly cover the positive and negative electrode sheets. Why are you doing this? As the coating is the basis of lithium battery production, it determines the consistency of the battery. Once the leavesCoated positive and negative electrodes, the positive and negative materials are relatively loose, and a certain pressure must be applied to the electrode sheets to compact the positive and negative electrode materials within a certain range.
Step 4: Divide. Depending on the battery model, the positive and negative electrode sheets need to be cut to the required widths. For example, in an 18650 lithium battery, the width of the pole piece is between 56 and 58 mm.
Step 5: Production and winding. Use a fully automatic film making machine to weld the positive and negative electrode tabs to the positive and negative electrode sheets. A fully automatic winding machine is used to wind the positive and negative electrode sheets and separator together into a cylindrical shape.
Step 6: Lower rolling trough and vacuum drying. The kernel is placed into the steel shell, the tab of the negative electrode is automatically welded, and the groove is automatically rolled. In addition, it is fired under high vacuum and high temperature to dry out a small amount of moisture, so that the performance of the lithium battery can be guaranteed.
