Why did the phone battery explode after being bitten by a young Chinese man?

The force from the Chinese man’s test bite can cause the two poles of the battery to come into contact with each other, causing a large release of heat.

The case of an iPhone phone battery exploding after being bitten by a Chinese man to check the quality at an electronics store in Nanjing city, Jiangsu province is the latest demonstration of how dangerous the company can be. Lithium-ion battery technology is in common use, Science Alert reported yesterday.

On January 19, the man brought his phone to change the battery. Worried about buying a fake, he took a bite to check the quality of the product. Just seconds after this action, the battery exploded but fortunately no one was injured in the incident.

According to scientists, external forces when causing breakage or breakage of the battery cover can simultaneously cause the negative and positive poles inside to come into contact with each other. A large amount of heat can thus be generated, causing an explosion.

Even in the absence of external force, the battery can still explode when dendrite fibers form inside. The presence of this conductive fiber on the other hand also reduces the life of the product.

The man’s act of biting the goods did not receive support on the Chinese video sharing site. “Phone battery is not gold, why bite it,” one person commented. Scientists also emphasize that biting the battery to test the quality is an action to avoid.
