MIT Secretly Built Mega-Efficient Nano Batteries

mattnyc99 writes "There was plenty of chatter last week about an MIT announcement that researcher Angela Belcher had developed a way to create virus-based nanoscale batteries to power mini gadgets of the future. In a fascinating followup at Popular Mechanics, Belcher now says that her unpublished work includes full-scale models of the batteries themselves, and that they could power everything from cars and laptops to medical devices and wearable armor. Quoting: 'We haven't ruled out cars. That's a lot of amplification. But right now the thing is trying to make the best material possible, and if we get a really great material, then we have to think about how do you scale it.'"

    When you discover something, typical procedure is to make a paper on it. Instead, MIT went ahead and worked on development before announcing the fundamental concept discovered. Maybe not "secret," but highly unusual.

    Bring product to market.

    Stop blabbering on and do it already.

    Think about what you're saying here.
    Is MIT, a university, going to bring this technology to market?

    We always hear about research because the people doing it need to show it off so that they can find business & manufacturing partners to bring it to market. Quitely shopping it around isn't the way its done.

  3. Not models. Prototypes. There's a difference. by Chris+Burke · · Score: 4, Insightful

    "A much-buzzed-about paper published in the Proceedings of the National Academy of Sciences earlier this month details the team's success in creating two of the three parts of a working battery--the positively charged anode and the electrolyte. But team leader Angela Belcher told PM Wednesday that the team has been seriously working on cathode technology for the past year, creating several complete prototypes. "

    "The cathode material has been a little more difficult, but we have several different candidates, and we have made full, working batteries."

    They've actually built things, that work, though the 3rd component the cathode is still apparently a work in progress. The summary says "models", which of course means something specific to /.ers, but that isn't the reality reflected in the articles.

  5. The advantages aren't clear by Ace905 · · Score: 3, Insightful

    It's obvious that weaving these batteries into fibre (for example) or just the fact that they can create such tiny batteries is hugely advantageous from an engineering perspective. Now clothes can be powered, etc.

    What isn't clear is why would you want these batteries to power your car? I don't really see any discussion on whether these pack more power than a 50lb car battery would. From the description it sounds like they're just regular batteries which expire, but are tiny. So by my no-math-involved logic, 50lbs of these nano-batteries should pack about the same punch as a regular 50lb car battery.

    Am I wrong about this? Do the infected bacteria constantly replenish the components of the battery making them more like a generator that runs on raw materials ? Because it doesn't look like that, it looks like they create the components, stop the process and put them together.

    Very very cool, but it sounds like the same technology we've always had is the end product. Please tell me I'm wrong, I want this to be the mini nuclear generator powering our cars we were all promised in the 1950's.

    I see nothing in those articles about these batteries being "mega efficient", as the title of this Slashdot post screams. The novelty seems to be the fact that they're grown using viruses and can be applied in thin films.

    Oh, no, that is not complete story of what this bugs could do. Think about it for a moment:

    1. those are big-molecule-sized particle batteries.
    2. You can construct them in such a matter that their terminals can be accessed only trough specific shape of (molecular, e.g. an enzyme) connectors.
    3. You can make each terminal incompatible with opposite polarity terminal, allowing for suspending those batteries in a liquid, or, if the batteries can bond with each other through (weak) hydrogen bonds, a large mass of them might already be in liquid form.

    Now, what is that all together? An "electric fuel", something that might power electric cars, but refuel on pump stations in same time ICE cars refuel. Car would have nanobatteries' processing unit, which would allow parallel connection of great many such batteries, pumped from the "fresh" tank. Once discharged in processor, batteries would be would be pumped into "used" tank.

    Bonus points for hypothetical clever battery design that would spoil terminals' shape if battery is empty as it would allow processor to be installed in "fresh" tank and just keep the tank stirred enough. Once processor squeezes out all the "juice", battery should fall off it, allowing connection with another, fresh battery to commence.

    There is just no pleasing some people. These guys have been consistently working away on a hard problem, making progress along the way, published their work, so others can run their own experiments, and worked towards a product.

    Meanwhile, what exactly have you been doing?

    But if we get more efficient at that (e.g. by building machines that then do the work with fewer human hours involved), we _should_, on average, have more free time for a given level of prosperity, right?

    And you most certainly could RIGHT NOW. You would just have to scale back your standard of living to the time when humans were doing all the work. Back to a family of 4 in a 1000sq.ft. home, with no AC and a max of one car per family. Going to see a movie would be an event. Most people prefer their McMansion with constant entertainment. "Stuff" cost money, and the level of spending generally outpaces the increases in pay scales.

    "Prototypes" mean something specific to us too.. and it isn't "2 out of 3 critical components, not even integrated yet".

    Actually, it can, because they can be prototypes of the components. Two of which have been integrated. And they've made full, working batteries, just not using their cathode technology yet.

    Why don't you just RTFA instead of continuing to poo-poo their accomplishment based on a single word taken out of context, the first one you latched onto not even existing in the article? Right, right, I must be new here.
