Nima uchun batareyalar portlaydi
Yaqinda Weibo’ning ba’zi foydalanuvchilari akkumulyator haqiqiy yoki soxta ekanligini tekshirish uchun savdo markazida tishlari bilan akkumulyatorni tishlayotgan erkakning qisqa videosini bo‘lishdi.
In Computer City, a man tried to replace his phone's battery at a counter, actually putting the battery in his mouth and trying to take a bite to test its authenticity. Result: The battery surface exploded after being pierced, but no casualties were reported.
Nima uchun batareyalar portlaydi?
Mobil telefonlar ham, noutbuklar ham lityum{0}}ionli batareyalardan foydalanadi, odatda lityum{1}}ion batareyalar deb ataladi. Batareyalar odatda elektrod sifatida litiy{2}}o'z ichiga olgan materiallardan foydalanadi.
Qisqacha aytganda, manfiy elektrod musbat zaryadlangan ionlarni saqlash uchun, musbat elektrod esa manfiy zaryadlangan ionlarni saqlash uchun ishlatiladi. Zaryadlash vaqtida litiy ionlari ma'lum vaqt davomida salbiy elektroddan musbat elektrodga o'tadi. Batareya ishlayotganida, lityum ionlari teskari yo'nalishda harakat qiladi.
The poles of the battery themselves should never touch each other, so the battery is placed in a gap between the north and south poles, if under the influence of external factors, such as the gap is broken, all the energy will flow to the battery's electrolyte instead of the north and south poles (electrolyte). The liquid is the carrier of the ion transport of lithium-ion batteries, and the electrolyte itself is a volatile chemical substance. After receiving too much energy, it contacts with the outside world, causing a lot of heat and even a flame explosion.
