FullBandwidth writes "Paper-thin batteries that can be printed onto greeting cards or other flexible substrates have been demonstrated at Fraunhofer Research Institution for Electronic Nano Systems in Germany. The batteries have a relatively short life span, as the anode and cathode materials dissipate over time. However, they contain no hazardous materials."

Laser printers, meboy! Sure the toner costs $100 for a replacement cartridge, but you can print 5,000 pages with one of 'em. And as a plus, it's got a laser in it! Quiet, fast, cheap...all made possible with the humble laser. Inkjet printers rightfully should be dumped into a hole in the ground.

Re:Free Energy, woo! (0)

Anonymous Coward | more than 5 years ago | (#29004103)

Laser printers are fine for printing very large amounts, but they have a very high upfront cost, especially if you want colour. I don't know where you got "cheap" from - you can get cheap laser printers but then the toner costs a similar amount to ink, except it's harder to find cheap non-OEM toner than ink.

Re:Free Energy, woo! (3, Insightful)

mlts (1038732) | more than 5 years ago | (#29004327)

You are right: I would say that inkjet printers do have a far cheaper upfront cost. One store would even give me a low end inkjet when I bought 2 ink cartridges that totalled over $50.

However, for the $30 an inkjet cartridge costs, I get about 100-200 pages. For the $65 a toner cartridge to a very low end HP laser printer, I can get 2500 or so pages, more if I bother to shake the toner cartridge. There is a big difference between three cents a page and 10-20 cents a page. To boot, with a laser printer, there is no streaking, no clogged nozzles, no wasting of ink on clean cycles, and no waste of ink. I can either use a laser printer once a month, or once a day. The toner will be used at the same rate, compared to ink which dries up and has to be cleaned off the heads.

Best results? Have both. I have an all in one inkjet I use for photo printing because it can print to photo paper. I also have a black and white laser printer for larger jobs.

Why do Germans invent so much technology? (-1, Troll)

Anonymous Coward | more than 5 years ago | (#29000863)

Printable batteries is another amazing technical achievement by the Germans. To that achievement, we can add the invention of calculus (co-invented with an Englishman), rocket technology (that eventually became the Saturn V), part of the foundation of quantum physics, automotive technology (beating Ford to the punch), etc. Why have the Germans (including Albert Einstein) achieved so much?

Why have the Africans achieved almost nothing in the area of pure and applied sciences?

Could the IQ difference be the reason? Average Japanese IQ and average German IQ is about 20 points greater than African IQ.

BadAnalogyGuy (945258) | more than 5 years ago | (#29000897)

If you are going to say that Africans are somehow less intelligent than other races, and then claim that is the reason there has been very little scientific progress made by Africans, you would also have to show how this holds true in non-African countries where Africans have moved and actually made significant scientific achievements.

In the United States alone, botanist George Washington Carver is well known for his work with the peanut, Lewis Latimer developed the carbon filament used in light bulbs, Garrett Morgan invented both the gas mask and the traffic signal, and Otis Boykin developed the pacemaker and the electronic control system for ICBMs. As you can see, this is scientific progress in both pure and applied science.

Perhaps you'd like to rescind your racist remarks.

You ignore the notion of a Gaussian curve. (-1, Troll)

Anonymous Coward | more than 5 years ago | (#29000927)

The average IQ of Africans is indeed 20 points below the IQ of Japanese and Germans. However, IQ has a Gaussian distribution. That some atypical Negroes (like yourself) may have developed minimal technologies (truly minimal stuff like a traffic light) does not prove that the average low IQ of Africans is an incorrect measurement.

The scientific accomplishments of Africans are almost non-existent. The grand-parent poster is correct in making that claim. He did not claim, "zero accomplishments". He declared, "almost nothing".

Most people working in Silicon Valley know that Negroes are nearly 0% of the high-tech workforce. If you want to work in an area where Negros are almost existent, then consider advanced mathematical research. You will find exactly 2 race groups in that area: they are Whites and Asians.

The racist here is you, Mr. Negro. You try to diminish the accomplishments of the Japanese using a verbal trick to equate the huge volume of Japanese technical inventions with the miniscule thimble of African technical inventions.

sonicmerlin (1505111) | more than 5 years ago | (#29001343)

I know I'll be modded down but screw "anonymous". When it comes to Germans you have to separate Ashkenazi Jews from the rest. Asians have higher average IQs than non-Ashkenazi whites (~100), but lower (average) IQs than Jewish people. The average IQ of black people situated in developed countries like America is actually 10 points higher (85) than Africans (75), most likely due to intermixing of races over the last few hundred years (those white girls on plantations sure got lonely back then). I also want to point out an experience I had at my high school some years ago. We had an Africa-American appreciation exhibit in our gym/auditorium, hosted by some third party organization. They put on display a bunch of items that Africans had invented over the last several decades. One of them was *the lunchbox*. My friends and I facepalmed and subsequently lolled. The other inventions weren't particularly impressive either. I imagine some black people make valuable contributions to society, but that organization sure didn't do a good job of demonstrating that.

Aging and leakage (3, Insightful)

BadAnalogyGuy (945258) | more than 5 years ago | (#29000771)

The biggest problem with aging materials is their propensity to leak. Take your mother, for example. When I first met her, she was in her 60's and had an ass like a drum. But after a decade of giving her the old backdoor to and fro, she now leaks like a sieve. I'd recommend taking her to get fitted for a colostomy bag, but that's your family's business, not mine.

So too with batteries. As they age and rust, the internal chemicals are liable to leak and cause serious harm to the environment. There really isn't any good way to dispose of these batteries that doesn't come at great cost or cause chemical contamination.

This development using organic compounds and no harmful lead or mercury is a godsend for those of us in the environmental movement. It has been a source of great consternation that greeting cards and other miniature throw-away gadgets have contained batteries with harmful chemicals, and now that seems to be a thing of the past.

It also has the side effect of making the card itself less bulky, so not only are you saving the environment by not polluting the groundwater, you're saving precious resources by buying products made of lighter materials.

From TFA:

Fraunhofer's batteries use zinc anodes and manganese cathodes, which react with one another to produce electricity.

My copy of the CRC Handbook does not list zinc and manganese as organic compounds. Do I need to upgrade my library?

While I agree that these elements do not currently have the bad press enjoyed, probably quite deservedly, by lead and mercury, I'm reminded of the calomel [wikipedia.org] taken as the primary medical treatment by the Lewis and Clark expedition. Scientific thought 200 years ago pointed to mercury as a cure for almost anything that ailed you. Times do change.

Make no mistake, I think that having printable batteries using zinc and manganese is a wonderful thing. I just want to point out that those of you in the environmental movement can be counted on to find something wrong with this technology too, if it becomes popular.

Re:Aging and leakage (2, Interesting)

bhima (46039) | more than 5 years ago | (#29001349)

My expectation is that the only way batteries are going to able to really compete with liquid fuels as an energy storage mechanism for vehicles is through some sort of comprehensive and mandatory recycling program. And I'm not just talking about just the actual batteries but rather a complete infrastructure and financing system which makes it difficult and expensive to ignore, opt-out or avoid. Otherwise, the whole thing will be an expensive and short lived boondoggle.

Having said that, I'd love to be able to build a 3D printing machine that could produce batteries and fuel cells.

Old news (and semi-dupe) (4, Informative)

Re:Old news (and semi-dupe) (5, Informative)

Anonymous Coward | more than 5 years ago | (#29001249)

Well there's a few differences between the two. Rensselaer's invention was largely based on cellulose whereas the Fraunhofer battery is a matter of zinc and manganese. While the Rensselaer battery actually seemed to be paper (and had the capability to be stacked to produce more power) the Fraunhofer battery seems to be "paper-thin" instead of actual paper. Also, based on the article, I find it unlikely the stacking for additional power output would work.

Further, Rensselaer said they weren't able to figure out a cheap way to mass produce. According to the article, the Fraunhofer battery seems to be fairly cheap already if they're "aiming at a price point under 10 cents per card" instead of a generic "We gotta make it cheaper."

They're similar technologies if all you think of it is "it's a thin battery", but in actuality are nowhere near the same.

fuzzyfuzzyfungus (1223518) | more than 5 years ago | (#29000845)

It'll be interesting to see whether he kills himself doing so or not. Batteries(of any standard chemistry, there might be something exotic out there) in parallel are pretty much harmless to any human who hasn't been flayed and dipped in graphite; but put enough of them together in series and you can get a pretty zesty high voltage DC source(youtube and friends are infested with videos of people playing with large quantities of 9-volts, they conveniently clip together in long chains for the purpose).

Not a huge surprise if you think about it; but anybody who thinks "Batteries = safe, Mains = dangerous" might be in for a surprise if they try on a large enough scale...

Re:Imagine a stack of 'em (2, Interesting)

Anonymous Coward | more than 5 years ago | (#29001027)

Some references would probably be in order: Here are 52 in series [youtube.com] . This is 160 [youtube.com] (warning, listening at nonzero volume might make you wish that the experiment had been less survivable...)

On the plus side, the ability of a 9 volt to deliver high currents isn't all that hot(compared to, say, a microwave transformer) so you'd be less likely to suffer massive damage from thermal effects, unless the lot caught fire. A similarly long chain of lead acid batteries would be substantially nastier in that regard.

That's because the 9 volt battery (deliberately) has quite a lot of internal resistance. Makes it much safer if there is an external short, at a cost of limiting it to low-current applications.

Re:Imagine a stack of 'em (0)

The 9V batteries in series will still deliver enough current to kill a human being though, so these experiments are definitely not recommended. It only takes a couple of milliamps across the heart to induce cardiac arrest.

I did something REALLY stupid when I was about 10 years old. I knew enough about parallel vs. series battery piles to be dangerous. Did you ever lick a 9V battery to see if it was good? If you got a really painful sting, it was good, and if it didn't hurt, it was probably too dead to run the game? Well, have you ever tried connecting 20 of those in series, making a pigtail and licking the conductors to see if it worked? I did. I learned a very quick lesson about that. I saw a flash of light and was dazed for a little while. I'm embarrassed to admit that here, but hey, I was only about 10 years old. Yep, I've always been a bit of a geek like that. That year I learned a lot of lessons: why a lot of batteries wired in series can be as dangerous as mains (my first mishap with electricity was when I was about five years old where the batteries in my pinball machine went dead so I made a cord to plug it into the mains - I fried both the outlet and the pinball machine internals), I learned why one should check the flyback circuit cables to make sure there is NO dry rot when working on internals a live (CRT) TV (or end up with a numb arm if there is a crack in the line and the screwdriver goes near it), why a magneto on a motorbike engine should not be played with while it's running. Those lessons were painful! :-D

This one time I found an old power-socket-to-lightbulb-socket adaptor thing when I was about 3 or 4. I decided to test it.

Um, yeah. Fill in the blanks yourself. [artlebedev.com]

My bet is a self contained house of cards with electric lights. A few hundred of the cards linked together should be able to power a handful of LEDs.

Power Paper [powerpaper.com] . Screen-printed zinc-manganese batteries on paper and polymer substrates are at least ten years old. (They're not the only supplier, either.)

Did nobody here take chemistry (1, Interesting)

Useful Wheat (1488675) | more than 5 years ago | (#29001391)

In my high school chemistry class we made paper batteries. We took a single piece of filter paper, and we took an eyedropper and we spilled various chemicals on the filter paper in an "X" pattern. You would then place a piece of metal (depending on your liquid, copper, zinc, lead) and put it on the paper, and figure out what combination of chemicals and metals gave you electricity (as measured by a handy multimeter). The entire thing was soaked with a saline solution so it conducted electricity. The exercise was fairly simple, and well understood. It was also one of the two labs we did in chemistry, which was really depressing because it was the "advanced class" and the loser normal class was making silver coated bottles, tie die shirts, candy, silly putty, and all sorts of things week after week. Stupid normal class with their fun and useful facts.

Anyway, I did this experiment in 2003. The real news story here should be, "New way to use something old." not "New and mind bogglingly challenging concept".

So will airport security be able to detect these ? (1)

PolygamousRanchKid (1290638) | more than 5 years ago | (#29001493)

Could a terrorist build some nasty device with these . . . ? I don't know why that's the first thing that came to my mind. Maybe because for that last eight years, governments and the media have been pounding a mantra into my mind: "Terrorist / Security / Terrorist / Security . . ." Soon it will be easier to print a list permitted items to take on a plane, as opposed to forbidden items.

Although, James Bond could pull one out of his sock to escape some bizarre execution method of the Evil Genius.

Or, Imagine a MacGyver armed with these . . . !

Great, you've just given Homeland Security an excuse to ban paper from being brought onto a plane.

Everyone knows it's blinking LEDs that explode. Ask the experts in Boston. They have foiled several menacing plots from the evil LED terrorists.

Need more desk space for all these printers (1)

So now I can print my own batteries, recharge them with my own printed solar panels [technologyreview.com] , to power my inkjet printed LCD panels. [nsti.org]

Awesome! If only I could get a printer that does the whole lot.
 

Zinc and manganese? (1)

Ol Olsoc (1175323) | more than 5 years ago | (#29012907)

Something a little strange there. Typically, a cell will use zinc, manganese dioxide, and another material as the anode. TFA only accounts for two of the three things needed. Possibly the surface layer of Manganese dioxide might serve as the electrolyte. But that battery wouldn't last long at all.

Unless they are being secretive.

Hopefully no one will discover the galvanic series, then their secret will be out!

All apologies for not making a inkjet or laser printer joke!
