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."
This sounds like more of an incremental improvment rather that the quantum leap that we need. And you'll still need a source of electricity to charge it. I'm still holding out for fuel cells.

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.

Thats pretty neat stuff, but what form will it have to take? We know the battery life in the nano, and micro world is neat, but does it help solve problems when it comes to cell phones? I know the article says it would be helpfull in cell phones, but will it merely be a smaller battery, or will the life of the battery be longer? I dont think it explained well how the actual life span of the batteries would be longer, except for one issue of how they would have less area to diffuse over. Could someone explain to me how this makes it last longer in a practicle sense, IE how would a cell phone use it?
If you don't vote, you don't matter, so don't waste your time telling me your opinion
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!!
AAAAAAAAAAAAh my fcking battery is dead!

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.
And you'll still need a source of electricity to charge it. I'm still holding out for fuel cells.
Why... fuel cells still need to filled. Are you saying you have a more ready supply of methane or hydrogen gas then you do electricity?
Power outlets exist in almost every man made structure in the industrial world. And in most cars too. I can charge my laptop/cellphone/PDA anywhere. The same can't said about the fuels used in fuel cells.
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.
Going a bit further, why not just put a miniscule amount of C4 in a bullet with those batteries and have explosive rounds? The 5.56 bullets we have now are effective, but simply lack the stopping power of an explosive-tipped armor-piercing warhead -- instead of a neat little hole in the head, which a mad terrorist could run through easily, why not just use C4-tipped rounds to destroy their head like a Gallagher-smashed watermelon?
Oh, and you're sexier than me and get more than I do.
I'm jealous!
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!

So, what would AAAAAAAAA-size mean? Where does this nomenclature come from and is there any logic in it?
I always forget which are which and end up calling them pen-size, index-size, thumb-size etc.

Go canucks, habs, and sens!
The one thing that scares me about that this post is the last line:
I can't wait until these batteries are available.
And what are you going to do with your 20-pack of mini C4 charges? Unless, of course, you are an army officer (I can't see why a private would be so excited about a new weapon).
I hereby place the above post in the public domain.
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!
Yeah. Maybe if we get even smaller they'll be able to make them for trolls. Although that would involve going to a scale even smaller than the one used by quantum physics...
God, just shut up.
I can walk around feeling a bit more confident now.
Does anyone know why sizes 'A' and 'B' aren't sold? Why the jump from AA to C ?
Cheers

Li-Ion batteries are a great improvement in terms of capacity over older NiCad and NiMH (Every time I see that, I think of that movie with the rats... but I digress.) technologies. In terms of price; however, I'm less than satisifed. My cell phone uses a Li-Ion battery and it seems like it's nearing the end of its useful life. You can imagine how shocked (pun intended) I was when I found out the cost of a replacement battery was equal to the cost I originally paid for the cell phone! The advances in battery technology are nice, but I'd be more than willing to accept bulkier batteries if they were a lot less costly.

Sounds like you want to go nuclear. To go nuclear, you can have your uranium or Americium in the center of a vat of water (to stop the neutrons, and gather heat). But you then need to export the heat to produced electricity. Most people would use a heat engine for that, but a heat engine is hard to miniaturize.
:
_ L__L__L__________ -N Volts
Here's a better way: use electrons as your heat engine gas, since electrons are both good at transporting heat and electricity, both, and have fewer accessible states than molecular gases.
Design: set a nanoscale series of pin grid arrays on top of each other, as shown below, and then run one wire from the bottom, and one wire from a flat collector plate at the top
__________________________+N Volts
_L__L__L__L__L__
_L__L__L__L__L__
_L__L_
Heat applied to the -N Volt plate causes electrons to boil away from the heat source, to the tips of the pins, where electric field lines concentrate, and cause the electrons to jump off the pin tips to the next plate. Essentially, the important thing is the radius of the pin tip divided by the area of the flat plate in front (same thing that sticks a balloon to the wall with static electricity). So you can run a wire out through the center of your power plate, and electricity will still flow as indicated.
So make two sets of curved plates, one in a hexagonal shape and one kind if a smaller pentagon shape, and assemble them around your spherical water vat, like a soccer ball.
Production: I suggest using acid etching, much the same as we do for PCBs. Actually, it might be possible to do this with standard chip making technology.

From what I understand Energizer Lithium AAs are not rechargable.
Does anyone make recharble Li-ion AAs?
I know if you pull a NiMH or NiCd battery pack apart, one useally finds that the battery pack consists of standard NiMH or NiCd recharble 'C', 'A', 'AA' or 'AAA' batteries inside the buggers. So designing the appliance to use some odd shape battery pack was just a way of making extra money selling special appliance specific battery packs that are in reality normal rechargables.
So do Li-ion battery packs, consist of standard size rechargable cells, when pulled apart?
& why arn't Li-ion recharble AA or AAA batteries avaliable?
Can you imagine the the fun people would having trying to sell these things in Liverpool?

Per your request, I will.
