No wonder thae battery is irreplaceable.
In the last 30 years, we've gone from having a room full of hard disks storing 32GB, to a memory chip the size of your fingernail storing the same.
In that same time period, batteries have improved a little bit. I understand it's a "harder" problem, but it'd really be nice if people were working on it.
Are you joking?
Consider that electric cars are using similar tech as laptops; there is a lot of battery research.
(Google e.g. lithium air, I believe that is the latest great hope for getting rid of the oil dependency...)
It's just depressing how much batteries suck.
Why can't we buy AA batteries that last a month constant usage now? Probably because then we'd buy less batteries, and people are unlikely to buy more expensive batteries.
Anyway, some new startups working to shake things up would be cool IMHO.
OK, so not kilotons, but not something you want to carry around either.
Regarding internal resistance, the resistance of all materials drops when they get sufficiently hot, and even a volt or two is enough to get an arc going. Once that happens it will spread until the entire battery is converted to plasma. Given the energy densities the other commenter hoped for, the propagation rate is likely to be at the speed of sound, in other words a high-order explosion. Which is not surprising given that such a battery would amount to a stick of dynamite with electrode layers spaced every few molecules.
In that same time period, batteries have improved a little bit."
And a good thing! If batteries had improved that much, the outcome of a short circuit would be measured in kilotons.
The only bad thing is it was a bit deflating to see the thing disassembled while I'm still waiting for UPS's very slow (in subjective terms) delivery today.
Isn't that battery type particularly prone to explosions (seriously!)
