Not only these hoverboards, a couple of days we made a news about a Tesla, which got overheat during the charge in a supercharge station and almost melted because of the fire.

So avoiding this accident and extend the life of the batteries, the researchers from Stanford University created an elastic film that. The film contains spiky nickel particles that surround the battery. When the battery starts to overheat, it begins to expand. When this expand happens, the conductive metal particles begin to move away from each other, and this shuts down the battery, and it starts to cool down. When the cooling down happens enough, the nickel particles touch each other and battery starts working again. This shutting off also extend the life if the battery If this technology starts the used by battery producers, we can see a less deadly accident that cause by batteries. This technology will make people trust the devices which use batteries.
