Who is the main culprit in the explosion of mobile phone digital batteries? Why does the mobile phone battery explode? Let ’s follow Shenzhen Chaofutong Digital Battery Manufacturer

Frequent battery explosions in mobile phones have led many civil aviation authorities to issue "blocking orders" for them. Why does a small and convenient mobile phone battery explode? This depends on how the mobile phone battery works.

Mobile phone digital battery works:

Mobile phone batteries are generally lithium-ion batteries. Lithium-ion batteries are composed of a positive electrode, a negative electrode, a separator, and an electrolytic solution. The positive and negative electrodes are impregnated in the electrolytic solution, and lithium ions move between the positive and negative electrodes using the electrolyte as a medium to realize the charging and discharging of the battery. In order to prevent the positive and negative electrodes from being short-circuited by the electrolyte, the positive and negative electrodes need to be separated by a separator.

The culprit in the explosion of mobile phone digital batteries

To increase the energy density of batteries, cell phone manufacturers have used thinner diaphragms to store more power in a limited volume. The reduction in thickness increases the difficulty of the production of the separator, and it is easy to cause quality defects, making the separator unable to effectively isolate the positive and negative electrodes, and then causing the short circuit and explosion of the battery.
