Lithium-ion batteries are notorious for overheating, catching on fire, or exploding. Yet, they're in most electronics that people use daily.
One such battery set ablaze over the weekend while in a man's pants pocket, according to the Associated Press. The man was walking around with his Samsung mobile phone in his pocket when the battery caught on fire, giving him second-degree burns and a one-inch wound on his thigh. Officials said the battery was not inside the phone when it exploded.
The incident took place in South Korea, which is where Samsung is based. According to the local newspaper the battery was from a 2011 Galaxy Note, although the Associated Press said that is still unconfirmed.
This was the second known time in the last year that a Samsung battery has caught fire in South Korea, according to the Associated Press. However, the smartphone maker told the news outlet that it was not planning an investigation.
