Solid State Lithium Battery
19th August 2015
Researchers at MIT and Samsung have built a battery that eschews the use of liquid electrolytes in favor of a solid state substance that offers some serious benefits.
Most commercial lithium-ion batteries use a liquid electrolyte to transport charged particles and provide power. But there are problems with this – the liquid degrades over time, and if the battery leaks there are serious safety issues.
“All of the fires you’ve seen, with Boeing, Tesla, and others, they are all electrolyte fires,” said Gerbrand Ceder, visiting professor of materials science and engineering at MIT.
“The lithium itself is not flammable in the state it’s in in these batteries. [With a solid electrolyte] there’s no safety problem — you could throw it against the wall, drive a nail through it — there’s nothing there to burn.”

Yeah, yeah…just tell me where I can buy one for my power drill.
