An unlucky man, Amine Britel, was left with serious burns across his abdomen after the battery in his electronic cigarette exploded in his jacket pocket. The whole incident was caught on a nearby security cam and it is a spectacular and sobering reminder of how dangerous lithium-ion batteries can be when they go bad.
According to the Daily Mail, Britel says he bought the aftermarket, Chinese-made battery at a local shop in France and plans on suing the company that manufactured the battery. The cause of the explosion is unknown, but Britel thinks that change in his pocket might have caused the potentially faulty battery to short out, leading to a particularly intense but relatively straightforward runaway energy release that is characteristic of critically failing lithium-ion batteries.
Chances are that the quality of the battery was less than stellar, but Samsung's recent and unending struggle with exploding Galaxy Note 7 phones shows that even the best, biggest brands in the business can run into trouble on this front. The fact of the matter is that lithium-ion batteries are inherently explosive and, until some better tech comes along, your best defense against having one explode on you is due diligence and avoiding any sort of DIY modifications to a device that uses a battery, especially a big one.
