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...
