AAAAAAAAA-size Li-Ion Cells
Jasin Natael writes "Thought Li-Ion batteries were all the same? Think again. Several universities, under a grant from the US Office of Naval Research, are
miniaturizing the anodes and cathodes of Li-Ion batteries to nanoscale, hoping to make more efficient, smaller cells that last longer."
soon I won't be able to use my second favorite excuse for getting off the phone:
my batteries about to die.
thanks a lot...stupid progress. I yearn for the good ole days, when cell phones were the size of small dogs and hurt your arms holding the things.

oh please! change the subject!
It scared the shit out of me when I read it as "lion cells" and the "AAAAAAAA" seems like a scream of someone being eaten alive in one of those lion cells!
We had enough lion-fodder during the roman empire...
That would be an Å-size battery.
I have a nokia 8000 series phone (i forget the exact model, it's not printed anywhere, oddly)
:P
It's a few years, and pretty 'primitive', but when I'm on the phone that thing get's hot. Not unbearably so, although it does almost get uncomfortable to hold up to my ear.
If these add-ons need so much more power then current cell phone batteries, then they would need to put out a lot more heat too. After all, 1 watt of power used equals about 1 watt of heat produced (not counting things like lights, or EM radiation).
IMO those things would be better served by smaller, cpus with more computational power per unit of actual power.
Of course longer battery life would be helpful to
autopr0n is like, down and stuff.
Now where did I put that battery...
all the guy wanted was to submit a Slashdot story that would show up first in alphabetical order.
This is a constant, dependant on the substance used in the battery. They may get 10 percent more watt hours in this battery. Peak current should be better, due to larger surface area of the anode/cathode. Lithium Polymer batteries have a higher energy density BTW.
The law is a weapon of the government, not a protection for the likes of you. Surely you understand that.
The problem is that batteries can't be recharged in 10 seconds. Tanks can be filled that fast. My battery dying wouldn't be nearly as big a problem if I could recharge it in 10 seconds. Plus, if fuel cells became popular, the fuel would quickly become available everywhere.

You know the scary thing? I read "lion" as being Lithium Ion right off the bat. Even the AAAAAAAAAAA as being a play on AA/AAA size batteries.
"Lion", as in the animal, never once occurred to me until I read your message.
Frankly, your interpretation would make more sense to the world at large. Proof positive that I need to get out more!

You can't scale things down like this. Rules change as you get smaller. Cells, as in human cells, don't have little batteries with discrete anodes and cathodes floating around. The way cells use energy is fundamentally different from a battery. People will have to shift their point of view away from making 'big things small', and start thinking in different ways. It is possible to miniaturize vacuum tubes, for example, but to get really small circuits there had to be a (sigh.. marketroid speak, but it works well) paradigm shift. I think the same thing will happen with energy storage.
Mostly random stuff.
These little batteries can be used in tiny little dildos that attach themselves directly to a women's clitoris. They can wear them whenever they go out, when they go to work, or during a date.
They can even wear them during sex and they won't have to fake orgasms anymore. The man will think he's studly and the woman will be satisfied. None will be all the wiser and there will at least be peace on earth.
Oh happy day!
Are you saying you have a more ready supply of methane or hydrogen gas then you do electricity?
;)
Actually, aside from 'technology', the enormous abundance of methane on Earth is the most easily-detectable sign that life exists here.
And what produces more methane than bovine flatulance? Nothing.(well maybe a Mexian rodeo)
Why do you think space aliens are always stealing/mutilating cows? It's because they think the cows are the dominant form of life here. And they might be right. =P
So anyway, eat a bean burrito and fill up your fuel cell, it's cheaper than buying batteries.

It's for the same reason that condom sizes are never small, medium, and large; instead they are large, extra large, and 'Oh my God!'
Ho! Haha! Guard! Turn! Parry! Dodge! Spin! Ha! Thrust!
A batteries? In what alternative universe did you guys find A batteries? Virtually no one makes them today, or B batteries either. The letters are part of a standard for single-cell batteries devised by the American National Standards Institute, or ANSI, beginning in the 1920s. (I realize that, strictly speaking, a battery consists of two or more cells, but let's not get picky.) Today the standard sizes range from AAAA to G, and for some reason there's also J, N, and 6. AAA, AA, C, and D were the only sizes that caught on in a big way commercially, but the others haven't totally disappeared. If you pry apart one of those big 6-volt lantern batteries, you'll find four F cells inside.
