How lithium batteries are made？-CSIP

Step 1 Dosing

 
High vacuum completely automatic mixing of accoutrements for 10 hours to disperse the accoutrements needed for lithium batteries to ameliorate the thickness and overall performance of the batteries. Why do this? Because dosing is the core area of lithium battery product and poor dosing directly affects the performance of the lithium battery. 
 

Step 2 Coating 

 
Borrow automatic lading system, borrow automatic cutter conforming system and online consistence dimension system to fleece the positive and negative electrode pieces unevenly. Why do this? Because coating is abecedarian to the product of lithium batteries, and coating determines the thickness of the battery. 
 
 

Step 3 Roll alignment

 
After the positive and negative electrode wastes are carpeted, the positive and negative accoutrements are fairly loose and need to be given a certain pressure to compact the positive and negative accoutrements to a certain range. 

 
Step 4 incising

 
Depending on the type of battery, the positive and negative electrodes need to be slit to the needed range. For illustration, for 18650 lithium batteries, the range of the pole piece is within 56- 58 mm. 
 
 

Step 5 Producing and winding

A completely automatic product machine is used to weld the positive and negative lugs to the positive and negative electrode wastes. A completely automatic winding machine is used to wind the positive and negative electrodes together with the diaphragm into a spherical shape. 
 

Step 6 Point bottom rolling groove and vacuum drying 
 

The core is placed in the sword shell, the negative lugs are automatically welded and the groove is automatically rolled. In addition, it's also ignited at high temperature under high vacuum to dry out a small quantum of humidity so that the performance of the lithium battery is guaranteed. 
 
 

Step 7 Chemical composition 
 

The lithium battery needs to be tested for charge and discharge before payload, and the battery is charged before leaving the plant. 
 
 

Step 8 Assemble the lithium battery 
 

Automatic welding machine, multiple battery assembly with connecting pieces welded together, and also installed on the circuit board, in the aging test, examination shipments. 
 

In short, the process of making quality lithium batteries for electric vehicles is veritably rigorous, because only also can its quality be guaranteed. For druggies, the choice of lithium batteries should be more conservative, don't be greedy for cheap, so as not to encounter poor quality lithium batteries.
