How to assemble lithium iron phosphate batteries for electric vehicles?

Electric vehicle lithium iron phosphate battery packaging method Electric vehicle lithium battery complete assembly equipment has four parts: raw material testing equipment, finished product manufacturing equipment, finished product testing equipment, and finished product packaging equipment. Lithium battery packaging and processing production technology is very strict and complicated. Different types of lithium batteries have different processing technology and numerous processing equipment. If you do lithium battery packaging, the equipment is not much, and the production equipment of about 10,000 yuan can be assembled and processed in a small size. The first step: the ingredients are mixed with high-vacuum and fully automatic materials for 10 hours, and the materials required for the lithium battery pack of electric vehicles are evenly dispersed, which improves the consistency and comprehensive performance of the battery. 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. 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. Step 4: Slitting According to the model of the lithium battery pack, cut the positive and negative plates 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 film making machine for sheeting and winding, weld the positive and negative lugs to the positive and negative sheets. And using a fully automatic winding machine, the positive and negative plates and the separator are wound together 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 pack for electric vehicles can be guaranteed.
