It is therefore wrong to drill holes to release air. The presence of water will cause the lithium battery components to decompose, swell, increase internal resistance, make charging impossible or even rupture. the damaged electrolyte, which is the origin of lithium hexafluorophosphate, an organic solution, non-toxic but corrosive.
What you're talking about is a leak. Under normal circumstances, lithium-ion batteries will not leak. As long as the quality isn't too bad, they will be. does not leak because lithium The outer layer of the ion battery is a hard shell or aluminum shell. However, after a long time, it may swell a little, but it does not affect the use. If the quality is bad, it will swell like a big belly~
Lithium-ion polymer battery, also called. soft packaging lithium battery, the outer layer is a polymer layer. If she ist breakthrough, the liquid you mentioned will flow out, with a slight scent (many people find it fragrant), and it will swell in severe cases. will catch fire. Therefore, generally do not disassemble the battery or puncture this type of battery. Don't be afraid of what I say. This type of battery is now widely used and is generally not dangerous.
