Why do some smartphones explode?


Today’s Video of the Day comes from the American Chemical Society’s Reactions series and investigates why some smartphones explode.

You’ve seen the news stories of smartphones suddenly exploding, prompting the TSA to ban certain models. But the explosions are actually caused by the phone’s lithium ion battery. Thermal runaway is the term used to describe when a battery suddenly explodes, and it’s typically due to any of the following reasons:

  1. Over-charging the battery
  2. Poor manufacturing
  3. Over-heating
  4. Physical damage
