HOW THE SAMSUNG GALAXY NOTE 7 BATTERY EXPLODES

Surely, the Samsung Note 7, could explode…….you can find the reasons below why her newly manufactured smart phone explodes…….C/NET

*You plug your Smartphone into the bedside charger and place it on your lamp stand with care, only to find your lamp stand in flames in the morning.

You keep it in your Jeep, on your hotel table, your dining table or your entire home; same thing occurs.

THE BASICS

The science behind phone batteries is actually pretty simple and fairly well understood. Most smart phones make use of lithium ion battery packs for their power, and it’s just so happens that the liquid swimming around inside most lithium ion batteries is highly inflammable.

If the battery short-“circuits”, say by puncturing the incredibly thin sheet of plastic separating the positive and the negative sides of the battery-the puncture point becomes the path of least resistance for electricity to flow. This heats up the electrolyte at the spot. And if the liquid heats up quickly enough, the battery can explode.

Galaxy Note 7 certainly isn’t the first phone to catch fire or even the first giant recall. By 2009, Nokia recalled 46 million phone batteries that were also at risk of short-circuiting. Exploding phones as a result of short-circuiting have allegedly killed people.

Though no brand is necessarily safe: for example, unluckily iPhone owners allegedly suffered nasty burns in 2015 and also in 2016. As though Galaxy Note 7 is making headlines right now, other Samsung phones have also burst into flames like the Galaxy core that allegedly burned a 6-year old child.

We’ve known for years that lithium ion batteries pose a risk, but the electronics industry continues to use the flammable formula because the batteries are so much smaller & lighter.

REASONS:

According to an unpublished preliminary report sent to Korea’s Agency for Technology and standards, Samsung had a manufacturing error that “placed pressure on plates within battery cells” which brought negative and positive poles in contact. The thin plastic layer that separates the positive & negative sides of the battery got Punctured, became the shortest route of electricity to zap across the battery (that’s why they call a “Short Circuit”), and became a huge fire risk.

WHAT DOES PRESSURE HAVE TO DO WITH IT?

MIT materials chemistry Professor, Don Sadoway explains that today’s cell phone battery are made of literally pressing together a stack of battery components- and that battery companies are under pressure to claim in as much capacity as possible.

At first, Sadoway has two theories; perhaps, Samsung simply pressed so hard that the positive and negative terminals poked right through the separator and managed to touch. OR perhaps it’s the sponge-like separator itself got squished. Normally, says Sadoway, the separator allows the liquid electrolyte to pass through pores connecting the positive and negative sides of the battery, even as it keeps the two terminals separate. “If they press really hard they constrict the pores, the resistance goes up & you heat more heat”, says the Professor.
