How are 3.7 volt 18650 lithium battery made?

　　After years of development, the lithium battery industry chain has formed a complete industry chain with a high degree of professional division of labor.

　　With the implementation of new national policies and the promulgation of new national standards for battery vehicles, the proportion of lithium electric vehicles in the sales market is also increasing.

　　How are 3.7 volt 18650 lithium battery made? Do you know? What are the production steps?

　　1. Homogenize

　　Mix the electrode active material, binder, organic solvent, etc. together, mix and disperse thoroughly, and mix into a slurry.

　　2. Coating

　　The slurry is intermittently and evenly coated on the surface of the transmission current collector and dried to form positive and negative pole piece rolls respectively.

　　3. Cold pressing

　　After the positive and negative electrodes are used, the materials of the positive and negative electrodes are relatively sparse, and the working pressure of the electrode plates must be given.

　　4. Cutting pieces into strips

　　Depending on the cell model, the positive and negative films must be divided into pairs of total width.

　　5. Winding

　　Small strips of positive and negative electrode plates and a separator are rolled together to form a bare cell.

　　6. Shelling, spot welding, vacuum drying

　　Wrap the exposed lithium-ion core in aluminum platinum, heating the top and sides. In addition, through the high-temperature heating of the high vacuum pump, a small amount of moisture is dried, thereby ensuring the lithium battery characteristics.

　　7. Injection

　　Lithium battery electrolyte is added to the lithium core, and the lithium core is completely sealed.

　　8. Formation

　　After assembly, a certain current is given to the rechargeable battery to produce positive and negative chemicals and negative chemicals inside the battery.

　　9. Divide capacity

　　During the entire manufacturing process, due to processing technology, the specific capacity of rechargeable batteries is inconsistent. According to certain charging tests, rechargeable batteries are classified by volume.

　　10. Forming

　　The appearance of the lithium-ion battery cell undergoes final processing.

　　High-Quality Batteries The car lithium battery production process is very careful, because only in this way can its quality be guaranteed.

　　However, the quality of the current lithium battery sales market is uneven. Therefore, when choosing a lithium-ion electric vehicle, do not be greedy and cheap, and try your best to choose one that is well-known and reliable and has guaranteed after-sales service!
