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...

During the production process of batteries, there may be fine dust particles and impurities in the air, as well as dust and burrs on the positive and negative electrodes. These factors can easily cause physical contact inside the battery and induce short circuits, greatly affecting its performance. In severe cases, it may even cause the battery cell to fail to charge, resulting in a "dead" battery...
