It seems like we're always hearing about the next big thing in battery technology, but they seem to stay in research forever, and never hit the consumer market.

The most exciting part of this, is that they say the'll be in consumer devices early 2017.

I'd love to have one in my quadcopter!

Progress in batteries has come a long way in the last 20 years. It's one of the reasons your quadcopter is even possible.

Do you know of anywhere that charts improvements in commercially available batteries? I have a similar impression to OP, but only based on anecdotes.

Note that having a compressed energy ready for rapid release is exactly equal to handling an explosive in your laptop :)

There are a lot of experimental batteries that have like 5x capacity of the current Li-ion ones, but melt and explode when heated or crushed, which makes them effectively useless.

This is one of the hardest problems in high-capacity batteries - to avoid "rapid unscheduled heat dissipation" and the following "rapid unscheduled disassembly".

Is it the case that the research was publicly-funded, but the profits are now being privatized?

American government funded research that turns into a business creating jobs in America sounds like a reasonable outcome to me. After China stole solar, we need some other industry with growth potential.

Edit: Do the down voters care to comment? Anti-nationalism, anti-capitalism, or what?
