alt Hacker News> something I can really buy
What are you going to use them for?
Consumer batteries are already good enough IMO. Cheaper batteries in large quantities are what we need more of.

I would agree if I could buy a AA battery that would power my toothbrush for a year. Or one that could be rechargeable with easily-available chargers reliably for a decade (and without having to drop 0.2V to achieve it...).
Any kind of consumer power technology can only ever be truly "good enough" if it never causes any inconvenience or significant cost.
Smartphone batteries that last a month instead of just a day would be nice.
