Over the next decade, solid-state lithium batteries will likely become commercialized. That should provide enough headroom to keep the improvements going for quite a while.

Standard manufacturing and scale improvements should keep things going for several more years, even without a major change to chemistry.

the new solid state lithium batteries being developed are pretty astounding. i think i saw a video of a phone being powered by one, then the demonstrator cuts the battery in half while the phone is being powered by it and nothing happens -- the phone stays on.

could have been video trickery but I think the demo was legit. Once that technology goes mainstream it's gonna be as revolutionary as the increases in lithium ion energy density. We're on the cusp of some incredible battery breakthroughs in the very near future! The fact that the new tesla roadster (admittedly expensive at $250k) has a 600 mile charge capacity is aboslutely astonishing.

oh interesting. definitely not the video i remember seeing, but that demonstrates the same thing very well, and makes me more confident that the previous video I saw was legit. thanks for sharing!! The cutting action happens around 32:07 for anyone wanting to watch
