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...
