Introduction of common equipment in the production process of lithium battery packs. If you want to ensure the quality of lithium battery packs, you must ensure that the production equipment for producing lithium battery packs works well.
There are many steps in the production of lithium battery packs, and there are many production related equipment.
The main production steps of the lithium battery pack
Pulping
The special solvent and binder for pulping are mixed with the powdered positive and negative active materials respectively, and stirred at high speed to form a slurry of positive and negative materials.
Coating film
The coating film is uniformly coated on the surface of the metal foil, dried, and made into positive and negative pole pieces respectively.
assembly
The assembly is carried out according to the positive electrode sheet--separator--the negative electrode sheet--the separator is placed in the order from top to bottom, and the battery core core is wound up, and then the electrolyte is injected, the sealing process is completed, that is, the assembly process of the battery is completed. Made into a finished battery.
Chemical detection
The product is charged and discharged with a dedicated battery charge and discharge device. Each battery is tested and the qualified finished battery is screened out.
For the production equipment used in these production steps, Cuneng Electric Xiaobian will focus on some important production equipment below.
The main production equipment of lithium battery pack
Coating machine
The coating machine is specially designed for coating the positive and negative electrodes of lithium battery packs on aluminum foil and copper foil. The high-end coating machine has the advantages of extrusion die method and continuous coating, which can provide better coating. Cloth effect.
Winding machine
The winder is mainly used for the winding of lithium battery pack batteries. It is suitable for pole pieces and various diaphragms. Good winder can automatically wind, automatically change needles, automatically paste tape and automatically cut, easy to operate, efficient.
Heating and shaping machine
The heating and shaping machine is also specially applied to the electric core. The heating plate is made of brass plate, which has good thermal conductivity, safety and environmental protection.
Sealer
Sealing and welding machine is a plastic welding machine dedicated to welding lithium battery packs or large and irregularly shaped thermoplastic workpieces. It is a reliable and extremely durable plastic welding machine with quick setting, quick mold change, simple and intuitive Program control and extremely high security features.
The steps of lithium battery pack production are actually relatively cumbersome. The contents of the production steps are only a general overview. The application range of lithium battery packs is also more common, so the safety of lithium battery packs is also worthy of attention. Not only should we pay attention to whether there is a problem in the production process, but also pay attention to whether the production equipment is running stably.
