About the post-processing process of lithium battery intelligent manufacturing

　　In recent years, with the rapid development of the new energy industry and the continuous upgrading of new energy vehicles and power battery industries, battery factories have increasingly higher requirements for automation and compatibility.

　　1000+ elite executives from vehicle companies, core component companies, and parts companies gathered together to discuss new cooperation models, strengthen the deep integration of the new energy vehicle industry chain, and promote the healthy development of the industry.

　　Next, let’s talk about SEI. During the first charge and discharge of a liquid lithium ion battery, the electrode material reacts with the electrolyte to form a passivation layer covering the surface of the electrode material. The passivation layer is an interface layer with the characteristics of a solid electrolyte.

　　Its role is:

　　First, the electronic insulator is an excellent conductor of Li+, and Li+ can be freely inserted and extracted through the passivation layer;

　　Second, the organic solvent is insoluble, which prevents the co-embedding of solvent molecules, avoids the damage to the electrode material caused by the co-embedding of solvent molecules, and greatly improves the cycle performance and service life of the electrode.

　　The third is the metal hard shell negative pressure formation process, which is characterized by the use of imported professional negative pressure solutions, good air tightness, long service life, accurate positioning of the application mechanism, independent intellectual property rights and low probe contact resistance, and two-way fire protection The program comes with a smoke exhaust and drainage system, dual monitoring of smoke and temperature. Another process is the soft pack, the battery of the soft pack needs to use the servo motor + sensor closed-loop control, and the pressure retention performance should be very good.
