World's Smallest Battery Created

Posted by Soulskill on Saturday December 11, 2010 @07:03PM from the only-need-fifty-thousand-of-them-to-power-a-phone dept.

Zothecula writes "Because battery technology hasn't developed as quickly as the electronic devices they power, a greater and greater percentage of the volume of these devices is taken up by the batteries needed to keep them running. Now a team of researchers working at the Center for Integrated Nanotechnologies has created the world's smallest battery. 'It consists of a bulk lithium cobalt cathode three millimeters long, an ionic liquid electrolyte, and has as its anode a single tin oxide (Sn02) nanowire 10 nanometers long and 100 nanometers in diameter.' (Abstract in Science.) Although the tiny battery won't be powering next year's mobile phones, it has already provided insights into how batteries work and should enable the development of smaller and more efficient batteries in the future."

Hell good luck finding a smart phone that doesn't have an iSliver of a battery.
  Until something like TFA comes out that will let iSliver batteries actually carry a decent charge I really don't think a step back from the shrinkage is too much to ask. after all what good is having all these functions on our "mobile" devices if it causes them to go through a charge like shit through a goose and makes us carry a charger around everywhere just to use the thing?

  Neither is he. What he's saying is that it's been Apple's general trend that, if function should come at the cost of form, that form tends to win.
  Personally, I got a high-capacity battery for my Droid Incredible. I loved the form factor of the handset as it shipped out of the box. However, the phone ate through battery life at a nearly unusable pace. The new battery pack brings the battery life to where it needs to be (i.e. still having a usable charge when I get home at night), but the touch-only phone is nearly as thick as my HTC Rhodium, and that one has a slide-out keyboard. Form won out on the Incredible too.
  It's the general trend that's a problem. Remember, there were plenty of people who carried around "Zac Morris" sized handsets in their day. Palm had a nice industry around PDAs, nearly all of which were larger than modern handsets and didn't include a cellular modem inside them. I'm def on board with the GP here; an extra 0.1 inches on a cell phone shouldn't be the huge deal it'd inevitably be made out to be, should it yield another 90 minutes of battery life.

  They're only called explosives if they rapidly release that energy. NiCad batteries for example are more dangerous than alkaline batteries simply because a dead short would heat up very quickly. Same for Lithium with the added danger of the battery itself burning. Increasing energy density is still very desirable - for example not having the battery in a car weighing 2-tons by itself.

  Not necessarily. What you want is something that is energy dense yet kinetically stable. Explosives are the opposite. Explosives deliver small amounts of power really fast. For example, the best explosives (according to wiki) are around 16 MJ/L and most around 3-5 MJ/L. Gasoline is at 34 MJ/L. If you want something that stores a lot of energy and won't explode, look no further than a pile of scrap aluminium. Aluminium stores roughly 83 MJ/L. You wouldn't be scared to have a ton of aluminium lying around behind your house, but that block could store enough energy to run your house for a year.

  That's not the reason. Keeping several dozen litres of easily flammable liquid in a tank and sending it to the engine by means of thin rubber tubing is dangerous too, but we do that all the time. If lithium batteries could be made with a much higher energy density than they have, they could always be placed inside armored containers - a bit like we do with LPG-powered vehicles. The reason is simply that the technology isn't there yet.
  
  When we pack a lot of energy in a stable state into a given volume, we tend to call those things "explosives".
  Not necessarily. If we could put as much research in LiFePO4 cells as it's gone in LiIon during the years, it's a safe bet they'd have a much higher density than they have now (approximately half that of LiIon), while still being perfectly safe. The only way a LiFe cell can start a fire is if it's misused - say, to send a whole lot of energy through a thin wire, that overheats and sets fire to something nearby. The cell itself can be folded, spindled and mutilated with no consequences. The danger is not in the amount of energy itself, it's in how it's stored. A log of wood has a lot of energy stored in it, but you're not scared by wood, are you?
  
  There's a fine line to tread here, and the more-efficient thing to do is reduce wastage than try to push battery abilities.

  I did the math a long time ago, one dull afternoon. I'll have to redo it again, since I threw away the idea and notes afterwards.
  How much Strontium-90 does it take to generate 1KWh? I came to the conclusion it requires more than a hundred pounds of Strontium-90, and that's assuming some 100% efficient way to convert radiation into usable electricity. This problem arises from the half-life of Strontium-90 being too long. A shorter half-life generally means more energy per second.
  So, if in some imaginary alternate reality Strontium-90 had a half-life 10x shorter, it would take 10x less mass to generate the same power output (instantaneous output, not "total").

  Sure if you ignore the meaning of "battery".

the problem with science today... by Anonymous Coward · 2010-12-12 05:17 · Score: 0

This is 100% marketing. What they did is interesting failure analysis of a nanowire, but this is nowhere close to the "smallest" battery. For about 10 years, scientists have been working with single site electrochemistry (that is, measuring and controlling changes in single chemical bonds... hard to get smaller than that). I've published on that myself (in Science, no less). Science magazine is blowing smoke here. The big publishers are destroying scientific integrity by putting "media marketability" above science. Authors are actively encouraged to inflate the importance of results and "tell the best story." Talking with Science and Nature editors in the last few years has made it clear that they're not interested in good research, they're interested in good soundbites. To them, the most frustrating part of being a scientific publisher is that the scientists insist on packing in pages of "data" rather than just submitting 2 pages of clever quotable phrases. They've been writing editorials on this for years, and shifting the "real science" in their publications from the journals to the "supplementary information." This whole system is fucked up.

Batteries are just fine, the devices need work by evilviper · 2010-12-12 18:11 · Score: 2

"Because battery technology hasn't developed as quickly as the electronic devices they power, a greater and greater percentage of the volume of these devices is taken up by the batteries needed to keep them running.
I take issue with the premise. It couldn't be more wrong.
A) Part of the development of electronics is reducing power consumption. If they're needing more battery power, its because they AREN'T developing very quickly.
B) The fact that we can make devices that use a lot of power isn't novel at all. The opposite is true. If you need massive batteries to make up for the rampant waste of your device, you apparently designed it quite poorly.
C) My new Droid2 has a much smaller battery than my 10 year old Cassiopia E-100; yet the battery life is about 25% better, this despite a 300% faster CPU, and builtin wifi, gps, cell, etc., so I'm hard pressed to see any way in which this the premise is objectively true.
D) Even back then (10 years ago), there was a huge disparity between the power consumption of comarable devices. Compare the 3 hour battery like of the E-100 with the approx. 1 month runtime of my Psion5mx (symbian-based). There are notable differences, of course, but the later was by far the better PDA all around.
E) And make no mistake, there's next to nothing you can name that smartphones do today that needs a super high-end CPU. Yes, I'm sorry to say you're paying hundreds of dollars on high end hardware solely to compensate for software bloat. MP3s worked just fine on Intel 386s. H.264 is the big one, but an integrated DSP can handle most of that heavy lifting.

  My 200MHz, 32MB RAM smartphone feels slower than the 4.77MHz, 640KB IBM XT I used as a teenager.
  I know clock-speed isn't the only measure of cpu speed, but seriously?
  I used to compile C code on that old thing, and it didn't feel too slow. Even just using the calculator or notes applet on my phone feels slow.
