Wonder if this is only Samsung or other mfg. also?

Putting it under pillow = bad idea to begin with.......

Lithium batteries occasionally get hot or catch fire or explode. ALL lithium batteries have the flaw in their genes, but only a very few combust.

Researchers Achieve
'Holy Grail' of Battery Design:
A Stable Lithium Anode

Engineers across the globe have been racing to design smaller, cheaper and more efficient rechargeable batteries to meet the power storage needs of everything from handheld gadgets to electric cars.

In a paper published in the journal Nature Nanotechnology, researchers at Stanford University report that they have taken a big step toward accomplishing what battery designers have been trying to do for decades – design a pure lithium anode.

All batteries have three basic components: an electrolyte to provide electrons, an anode to discharge those electrons, and a cathode to receive them.

. . .

An additional problem is that the anode and electrolyte produce heat when they come into contact. Lithium batteries, including those in use today, can overheat to the point of fire, or even explosion, and are, therefore, a serious safety concern. The recent battery fires in Tesla cars and on Boeing's Dreamliner are prominent examples of the challenges of lithium ion batteries.

To solve these problems the Stanford researchers built a protective layer of interconnected carbon domes on top of their lithium anode. This layer is what the team has called nanospheres.

The Stanford team's nanosphere layer resembles a honeycomb: it creates a flexible, uniform and non-reactive film that protects the unstable lithium from the drawbacks that have made it such a challenge. The carbon nanosphere wall is just 20 nanometers thick. It would take some 5,000 layers stacked one atop another to equal the width of single human hair.
