Viruses Boost Performance of Lithium-Air Battery Used In Electric Cars

Posted by Soulskill on from the go-get-a-sick-kid-to-cough-on-your-battery dept.

rtoz writes "MIT researchers have found that adding genetically modified viruses to the production of nanowires will boost the performance of lithium-air battery used in electric cars. The key to their work was to increase the surface area of the wire, thus increasing the area where electrochemical activity takes place during charging or discharging of the battery (abstract). The increase in surface area produced by their method can provide a big advantage in lithium-air batteries' rate of charging and discharging. Unlike conventional fabrication methods, which involve energy-intensive high temperatures and hazardous chemicals, this process can be carried out at room temperature using a water-based process."

  2. But when will we see it? by wjcofkc · · Score: 4, Interesting

    Granted, Lithium ion batteries have seen a number of enhancements over the years, but new super-ultra battery tech is starting to look like fusion - always around the corner. A battery that is all the way around a major step forward from what we have now could change the world overnight. But every time I read about the next big thing in batteries, I just sigh... I realize that continued articles means continued research and development is going - but I am ready for my super batteries now. I know I can't hurry science along, but I am eagerly and impatiently waiting for the day I wake up to the commercial realization of the mythical wonder-battery.

  3. MIT PR is becoming embarassing by Animats · · Score: 4, Interesting

    MIT's PR operation is becoming embarrassing. At least once every two months, there's some announcement about "nano" something that's going to change the world. Then we never hear about it again. You look at the details, and it turns out somebody did something at lab scale which might possibly someday be useful, if there weren't other ways to do the same thing already.
