Batteries are used in a lot of the technology and toys we use everyday, and the more they're used, the hotter they can get. But what if these batteries could turn themselves off before they got too hot and exploded?
Well, a group of researchers at Stanford University have created such a battery, which they claim is the first lithium-ion battery to have this ability.
In the above video, you can see that a simple LED and hot-air gun were used in testing and showed that everything worked as intended.
The group attached a battery to a special polyethylene film that reacts to heat, then filled it with spiky nickel particles that conduct electricity when they come into contact with one another. At a normal temperature, electricity is generated as it's supposed to, but when a higher temperature is reached, or when the team heated it up to above 160° F (70° C), the film expands, causing the nickel particles to separate and interrupting the flow of electricity.
