Batteries can be dangerous. Last year, Samsung recalled a whole line of phones because the lithium-ion batteries had a habit of exploding, and that they were faraway from the first ones to do so. an entire range of products, including hoverboards, vape pens, and even a nasa robot, have suffered from exploding batteries. but a gaggle of Stanford researchers may have found an answer.
It’s easy to forget that batteries are basically little bombs. They store large amounts of energy and are designed to release that energy on command. usually that happens gradually, but often one thing can go wrong and all that energy is free all at once. this can be the results of a manufacturing defect, overcharging, or damage.
A group of Stanford researchers try to fix this downside by developing a lithium-ion battery with a built-in fire extinguisher. Their battery includes a small shell containing triphenyl phosphate (TPP), a fire retardation, which is placed within the electrolyte liquid inside the battery. The shell is designed to melt at high temperatures, around three hundred degrees fahrenheit, releasing the TPP. In laboratory tests, this setup manages to extinguish fires in about 0.5 a second, long before any serious damage can be done
