Check out the, Samsung – here is the battery with built-in fire extinguisher – IDG.see

the Batteries can be really dangerous. It’s got Samsung’s bitter experience after the fiasco with the Galaxy Note 7 as exploded due to the error in the just the phone battery. But they are not alone, problems with lithium-ion batteries are not as uncommon as both manufacturers and customers would like. Researchers at Stanford may have found a solution to the problem.

Simply put, you can say that the researchers developed batterivärldens counterpart to the airbag. By, in practice, to build up a fire extinguisher in the lithium-ion battery, they hope to be able to cool the unit before it causes extensive damage. The chemical substance used is a kind of flame retardant called trifenylfosfat. It is put into a capsule then put in the battery elektrolytvätska. If the battery to overheat and reach temperatures over 150 degrees Celsius, then melt the capsule shell. Tests show that a fire goes off in 0.4 seconds, reports the BBC.

the Study is published in the scientific journal Science Advances. Previous attempts to build in trifenylfosfat, then without a capsule, has been proven to limit the battery power. If the cells in the battery charging too fast, or if there is a small manufacturing defect, it can lead to a short circuit. And the equipment can begin to burn. Since February 2016, warns the u.s. agency for safe transportation to store lithium ion batteries in flygplanslasten. They described them as a risk of fire and explosion.

the Analysts that the BBC has been talking with says that the battery technology many times have developed more slowly than the technologies they are intended to operate. The pressure on manufacturers is high when the right batteries are seen as one of the factors that hold back the development of phones and other products. The industry has found it difficult to balance the requirements of longer battery life and more products that require more energy to function.
