SEI (Solid Electrolyte Interphase) is also a solid electrolyte interface membrane. When a lithium-ion battery is charged and discharged for the first time, a small amount of polar aprotic solvent in the electrolyte undergoes a reduction reaction after gaining some electrons, and combines with lithium ions to form an interface film with a thickness of about 100-120nm, which is SEI. SEI is usually f...

In the production process of pouch cell battery, there are many factors that can lead to abnormal gas production, which can be divided into several categories: First, the film formation of the cell itself is unstable. In the subsequent cycle process, the SEI film on the surface of the negative electrode may fall off or become loose, and the SEI film(SEI Formation Machine) is reconstructed, accompa...
