That is really neat.  Now if they can only make them less expensive to manufacture and more power dense.

I'm old enough to remember when lithium batteries first came out -- non-rechargeable (primary) batteries first. They were delicate (couldn't get them very warm or they'd exotherm), and they couldn't put out much output current, but boy did they pack a lot of energy for their size!

Then for a couple of years, everybody was waiting for a rechargeable version. When they came out, they were called "lithium-ion" and they were great, except that you couldn't do much with them. They were still very sensitive to heat, and still couldn't put out much current.

But the technology continued to improve, and one day they could tolerate enough heat to be safe in workshop environments, and could put out enough current to power a cordless tool...if I remember correctly, it was Milwaukee that came out with the first one.

That's when the avalanche really gained momentum. We all know how the story goes from there.
