Printable Batteries Should Arrive Next Year

Posted by timothy on from the return-to-the-goodness-of-aa dept.

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.

      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.

  3. Aging and leakage by BadAnalogyGuy · · Score: 3, Insightful

    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.

      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.

      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...

      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
