--- Quote ---Laptops, airplanes, electric cars, and even the new rolling hoverboards have all faced troubles with lithium-ion batteries bursting into flames. But now, researchers report that they’ve come up with a potential cheap and effective way to prevent batteries from overheating. They’ve added a heat-sensitive polymer sheet to conventional lithium-ion batteries that shuts down their operation if the temperature rises too high. And once the temperature drops, the polymer sheet returns to normal, allowing the battery to come back to life.
