1: The internal polarization is large. 2: the pole water absorption, reacting the drum with the electrolyte. 3: The quality of the electrolyte itself, performance problem .
4: The amount of liquid in the liquid does not meet the process requirements. 5: assembly The laser welding in the process is poor, leakage, leakage, leakage. 6: dust, polar dust is first easily causing micro-short circuit.
7: The positive and negative poles are thick, the shell is difficult. 8: Nipple sealing problem, steel ball sealing performance is not good to cause gas drum. 9: The housing material exists thickness, and the thickness of the housing deformation.
The type of exploded type decomposing the battery core explosion can be summarized as an external short circuit, internal short circuit, Three kinds of. The external system here refers to the exterior of the battery, which contains short circuits caused by poor insulation design in the battery pack. Kur njÃĢ qark i shkurtÃĢr ÃĢshtÃĢ jashtÃĢ qelizÃĢs sÃĢ baterisÃĢ, komponenti elektronik nuk ndÃĢrpritet dhe pjesa e brendshme e qelizÃĢs sÃĢ baterisÃĢ do tÃĢ ketÃĢ nxehtÃĢsi tÃĢ lartÃĢ, duke rezultuar nÃĢ njÃĢ avull tÃĢ pjesshÃĢm tÃĢ elektrolitit dhe do tÃĢ mbÃĢshtesÃĢ guaskÃĢn e baterisÃĢ.
When the internal temperature of the battery is high to 135 degrees Celsius, the quality of the diaphragm is closed, the electrochemical reaction is terminated or near termination, the current is plummeted, and the temperature is slowly decreased, and the explosion occurred. However, the fine hole closure rate is too bad, or the fine hole does not close the diaphragm paper, which will make the battery temperature rise, more electrolyte, and finalize the battery housing, and even improve the battery temperature. Material burning and exploding.
The internal short circuit is to be because the brass foil is pulling the membrane of the aluminum foil, or the branches of the lithium atom wear the diaphragm. KÃĢto gjilpÃĢra tÃĢ holla mund tÃĢ shkaktojnÃĢ mikroqarqe tÃĢ shkurtra. Because the needle is very fine, there is a certain resistance value, so the current is not necessarily.
Copper aluminum foil burr is caused by processing, and it is observable. Moreover, since the glitch is small, sometimes it will be burnt, so that the battery will return to normal. Prandaj, probabiliteti i shpÃĢrthimit tÃĢ shkaktuar nga gÃĢrvishtjet nuk ÃĢshtÃĢ i lartÃĢ.
NÃĢ kÃĢtÃĢ mÃĢnyrÃĢ, ÃĢshtÃĢ e mundur tÃĢ keni njÃĢ bateri tÃĢ shkurtÃĢr tÃĢ ngarkuar brenda nga pjesa e brendshme e secilÃĢs prej qelizave. MegjithatÃĢ, ngjarja e shpÃĢrthimit ka ndodhur, por ÃĢshtÃĢ mbÃĢshtetur statistikisht. Therefore, the explosion caused by internal short circuits, it is still due to overcharge.
Sepse, ÃĢshtÃĢ njÃĢ kristalizimi i metalit tÃĢ litiumit nÃĢ formÃĢ gjilpÃĢre, dhe ÃĢshtÃĢ njÃĢ qark mikro i shkurtÃĢr. Prandaj, temperatura e baterisÃĢ do tÃĢ rritet gradualisht, dhe nÃĢ fund temperatura e lartÃĢ do tÃĢ elektrolitojÃĢ gaz. This situation, whether it is too high to make the material burns, or the outer shell is first striking, so that the air into the lithium metal is violently oxidized, all of which are explosion.
MegjithatÃĢ, ky shpÃĢrthim i shkaktuar nga njÃĢ qark i shkurtÃĢr i tepÃĢrt i brendshÃĢm nuk ndodh domosdoshmÃĢrisht nÃĢ momentin e karikimit. ÃshtÃĢ e mundur qÃĢ temperatura e baterisÃĢ tÃĢ mos jetÃĢ e lartÃĢ pÃĢr tÃĢ lÃĢnÃĢ materialin tÃĢ digjet. Kur shfaqet gazi, konsumatori nuk mjafton pÃĢr tÃĢ thyer kapakun e baterisÃĢ, konsumatori do tÃĢ ndÃĢrpresÃĢ karikimin, me celularin pÃĢr tÃĢ dalÃĢ jashtÃĢ.
NÃĢ kÃĢtÃĢ kohÃĢ, nxehtÃĢsia e shumÃĢ mikro-qarqeve tÃĢ shkurtra, ngadalÃĢ rrit temperaturÃĢn e baterisÃĢ, pas njÃĢ periudhe kohe, vetÃĢm shpÃĢrthim. PÃĢrshkrimi i zakonshÃĢm i konsumatorit ÃĢshtÃĢ tÃĢ marrÃĢ telefonin dhe tÃĢ zbulojÃĢ se telefoni ÃĢshtÃĢ i nxehtÃĢ dhe mÃĢ pas ka shpÃĢrthyer.
