A lab “accident” may solve your annoying battery problems.

[Onkel Neal]

I hope this is not like so many other science miracles and it fades away.

Batteries are terrible. Compared to many other methods of storing energy, especially fossil fuels, batteries aren’t very energy dense—that is, a 1-pound battery stores far less energy than is contained in a pound of gasoline. That wouldn’t be so bad if the energy in a battery were easy to replenish—your Tesla might still go only a couple hundred miles on a single charge, but if you could fully recharge it in five minutes rather than several hours, the low capacity wouldn’t bother you as much.
