Batteries with built-in fire extinguishers developed by Researchers

I wonder where the flame-retardant was when battery explosion rocked Samsung Galaxy Note 7 for month, later forcing the smartphone giant to shut production and of course recalled units of the device sold, well fast forward to the present time, some group of researchers at Stanford may just have found the best solution to prevent future occurrence of phone battery explosion with their newly developed batteries with built-in fire extinguishers

Without mincing words, we both know the most commonest Lithium-Ion battery problems is its very hot temperature while in use, in most cases when not properly taken care off, things gets ugly, well things is about to change, an article published on Science Advances titled “Electrospun core-shell microfiber separator with thermal-triggered flame-retardant properties for lithium-ion batteries.” explains how it works

How the batteries with built-in fire extinguishers works

According to the article, a protective layer with flame retardant properties would melt when battery gets too hot, interestingly, it will pout out fires even before it could start, The material used includes triphenyl phosphate, or TPP. Although this won’t be the first attempt such has been tried to help keep batteries from combustion

However, using TPP inside a battery can take a negative turn on the performance of a battery. but this new method ensures TPP is kept into a more protective shell separating it from the battery until temperatures are very high enough to melt the shell

While this looks more like a preventive measures aim at keeping an exploding smartphone from causing much damage, best solution however remains finding ways to keep battery temperatures from rising at the first instance to dangerous levels …Via : liliputing

Please don't go without sharing this article? Not fair 🙁..
