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."
where's the pictures?
One of the things that I've been waiting for is minature power cells, a la Star Trek. It was always really cool to me how equipment could be lugged around from here to there, apparently never needing recharged.
If it helps, maybe this moves us one step closer to having laptops that can be used as true portable computers, not needing charged for days or weeks at a time.

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.
WHY don't these SO-CALLED scientists simply place NORMAL SIZE batteries inside a DE-BIG-U-LATOR or similar device?
WHY waste TAXPAYER dollars (unless like me you HIDE your wealth in OFFSHORE TAX HAVENS) developing NAN-O-TECH when perfectly viable DE-BIG-U-LATOR techonology is available from your NEIGHBORHOOD GEEK!
I thought this PROBLEM had been LICKED! I wouldn't USE it anyway! MY CELL PHONE uses a HAND-TURNED CRANK to run the DYNAMO! That's PROGRESS!!
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.
Are you saying you have a more ready supply of methane or hydrogen gas then you do electricity?
Sure I do, but I'm not sure how I would ummm... harvest it, and maybe it's best not to discuss the matter in mixed company.
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!

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!
I can walk around feeling a bit more confident now.
As long the cat's not in a sealed box with a Uranium-238 atom and a geiger-counter wired to a shotgun, your conversations can be carried on indefnitely.

;)
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.

Well, since you're holding out for fuel cells,
I'll be holding out for Mr. Fusion (Back to the Future 2).
Chuck in something on the periodic table this side of iron, and you've got 1.21 Gigawatts for your cellphone to fry your brain.
Yay sarcasm!

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!
Oh great, my new boom box takes 8192 AAAAAAAAA batteries. (Sold separately)

Just imagine how much radiation thats giving off if its getting hot enough to touch. And yer holding it right next to your head. I even bet you put it in your pockets, so when it rings it's pointed right at your nads. Cell phones are the governments way of making sure all you people don't reproduce.
