The end of exploding gadgets? Researchers reveal lithium-ion batteries with built in flame retardant - lithium ion battery pack

In recent months, from the Samsung Galaxy 7 fiasco to the unexplained explosion of other phones, the horror story of the explosive gadget has dominated the news.
Now, researchers have found a new type of battery with a flame retardant material built in to prevent the battery from exploding.
Researchers at Stanford University have designed a battery with a built-in fire extinguisher to prevent high flammable substances in the battery from catching fire.
Scroll down to watch the video they used a flame retardant compound called tribenzene phosphate to separate the flammable components of the battery.
Typical lithium
The ion battery consists of two electrodes (one negative and one positive) and a liquid or gel electrolyte carrying charged particles.
Heat can be generated when the battery is perforated, short-circuited, or overcharged.
If the temperature reaches 300 degrees Fahrenheit (150 degrees Celsius), the electrolyte may catch fire and cause an explosion.
But with this new technology, when the battery reaches a temperature of 150 °c, the plastic fiber layer coated in the flame retardant chemical will melt, release the chemical and extinguish the fire.
Unless the battery reaches a temperature of 150 °c, the fiber separator will prevent the flame retardant from contacting the electrolyte, otherwise it will reduce the performance of the battery when the battery works properly.
During the test, the researchers found that this flame retardant substance was merged with flammable electrolyte in the battery in a time of only 0.
4 seconds to avoid the fire.
The researchers took videos of their attempts to burn fibers not coated in flame retardant materials and other fibers coated in flame retardant materials to understand the effects of chemicals in preventing fires.
While the new separation technology has been successfully tested in coin batteries, the researchers say more testing needs to be done to see when larger batteries are crushed or otherwise damaged, whether the flame retardant is still valid.
Samsung has encountered well-known problems with the note 7 model lithium ion battery.
After the Note 7 phone caught fire last year, the brand fell into a global scandal, triggering a worldwide recall. Koh Dong-
Samsung Mobile President Kim told reporters in Seoul: "defects in the manufacturing process lead to negative and positive electrodes gathering together.
It is not clear how Samsung found battery problems before releasing Note 7.
Some customers reported that the overheating of the fixed phone caused Samsung to recover the replacement as well.
Note 7 the first report of the explosion surfaced in South Korea on August 24, 2016.
A week later, Samsung announced a global recall of two.
5 million Note 7 mobile phone, there is a problem with the battery.
September 8, United StatesS.
The Federal Aviation Administration advises passengers not to turn on the Note 7 smartphones on the plane, nor to store them in aircraft cargo.
America, September 15. S.
The Consumer Product Safety Board officially announced the recall of about 1 million Note 7 phones.
On October, an American Southwest Airlines plane was evacuated due to smoke from the Note 7 equipment on board.
Finally, on October 11, Samsung asked its customers to stop using all the Note 7 smartphones and to stop the production, sales and communication of the device worldwide.
