What is the cause of zero voltage or low voltage in polymer lithium batteries

1. External short-circuit of polymer lithium battery, such as a pile of batteries falling to the ground, the tabs are overlapped and short-circuited, the positive and negative tabs are clamped on the same side when the battery is put on the cabinet. 2. Internal short circuit or micro-short circuit of polymer lithium battery, such as: the positive and negative electrodes have burrs and penetrate the diaphragm paper to contact the short circuit, the diaphragm paper does not cover the pole piece or just flush with the pole piece to cause a short circuit, etc. 3. Polymer lithium battery pole Ear break 4, the tab glue does not expose the packaging film, and the tab is connected to short-circuit the large-capacity lithium battery through the aluminum foil in the middle of the packaging. 5. The polymer lithium battery is not formed into a charge. The above five points are the possible reasons for the zero voltage or low voltage of the polymer lithium battery. When this happens, you can check one by one to see where the problem is! Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
