in the Face of incidents, many airlines and the authorities of aviation safety in countries such as Australia, Canada, Japan, Indonesia and India, have also prohibited the use of the Galaxy Note 7 on board aircraft. The risk of overheating of lithium batteries is not, however, a problem unique to the electronic devices. Many models of phones manufactured by Nokia, Apple, Toshiba, or Sony have already blown for this reason.

In 2006, for example, the brand of PC laptops Dell had to recall 4.1 million batteries for its computers because they transformed them into potential “flame-thrower”. A year later, Finland’s Nokia took the same decision in recalling to turn 46 million batteries for mobile phone after a hundred incidents across the world. Finally, more recently, at the beginning of the summer, the United States has recalled more than 500,000 hoverboards (kinds of skates, two-wheeled motorized), due to the risk of overheating, and, therefore, of explosion, of their lithium batteries.

“over The past twenty years, the lithium-ion batteries have earned three to four times energy density, while becoming smaller and smaller, explained the World in 2009, Rachid Yazami, a researcher at the CNRS. in This makes them more vulnerable to a thermal shock or physical, or a manufacturing problem.” Remains to be seen whether the new model of the manufacturer from south korea will face the competition of the new iPhone 7 Apple.
