Phone battery bursts into flame while charging in China

This is the moment a phone battery burst into flame while it was being charged.

CCTV filmed in an office in China on January 20 shows smoke seeping out from the device shortly before it fully catches on fire. A woman working at her desk is seen grabbing a book and smacking it down on the burning battery.

There were no injuries as the fire was immediately put out by the quick-thinking lady.
