Analysis of the causes of zero voltage in lithium batteries!button cell battery cr1620

release time:2023-08-23 Hits: Popular:AG11 battery

　　(1) The internal structure of the battery does not touch the operating voltage or current

　　(2) Short circuit fault on the cross section of the yellow adhesive ear of the lithium battery, resulting in leakage of the lithium battery packaging liquid

　　(3) The pole ear adhesive did not leak out of the packaging film, and the pole ear was faulty due to a short circuit in the aluminum platinum connection of the inner layer of the packaging box for a large space lithium iron phosphate battery.

　　(4) Lithium battery pole ear breakage: During lithium battery packaging, a short circuit fault occurred between the metal strip and the aluminum plastic film, resulting in a sudden leakage of liquid due to the thermal fusion sealing of the aluminum plastic film and the heating (around 140 ℃) during packaging.

　　(5) Short circuit faults in the external structure of lithium batteries, such as a large pile of batteries collapsing, short circuit faults in the overlapping of steel bars between the pole ears, and the positive and negative pole ears being clamped on the same side when the lithium battery is mounted.

　　(6) Short circuit fault or micro short circuit fault in the internal structure of lithium batteries, such as short circuit fault caused by rough edges on the positive and negative sides touching the protective film paper, the protective film paper not wrapping the pole piece or being exactly flush with the pole piece, etc.
