Have you ever seen an overheated lithium battery? When it overheats, it expands and erupts into flames. It’s the reason low-quality hoverboards keep exploding and can’t be taken on flights. When you are utilizing power tools to finish an enormous venture, battery life is an enormous drawback.Fortunately, Stanford researchers have created a Li-Ion battery that it shuts itself down when it overheats and turns itself back on when heat levels are at a safe level.
Lithium ion batteries are practically ubiquitous; they power everything from laptops and cell phones to cameras and tablets. But before they can start providing the juice for bigger and more demanding applications, research about their failure needs to happen. It is said that the change in temperature that lead to a destabilizing further change in temperature, elevates the risk for internal short circuiting and damaging any nearby components.
The technology involved in the research, apart from making rechargeable gadgets safer, will also extend the life of batteries that would have otherwise been damaged by overheating . To accomplish this, a thin elastic film with conductive spiky nickel particles that surrounds the battery is created by the researchers. When a battery heats up it expands. When that happens, the conductive metal particles move away from each other and it shuts down the battery. As the battery cools, the film contracts and the nickel particles begin to touch again, the battery turns back on.
Needless to say, if this polymer makes its way into all batteries, it will cut down on burns associated with electronics that overheat, making such technology safer and preventing them from becoming the origins of bigger accidents.
