Lithium-Sulfur Batteries Unveiled

Posted by CowboyNeal on from the amping-it-up dept.

mobilemag writes "Sion Power is showing off its new Lithium-Sulfur battery design this week at the Windows Hardware Engineering Conference (WinHEC). SION believes that its new Lithium-Sulfur (Li-S) batteries are the answer to the power hungry devices on the market today."

    How about instead of making better batteries, we make it so the electronics don't use as much electricity? I think working on effeciency would be better. If someone is more knowledgable about this subject, though, feel free to correct me.

      Of course they do that already. But there's only so low the power consumption can go and still provide reasonable performance.

      Personally, I think the laptop fuel cell mentioned in the article is a million times more interesting than this battery. Available as soon as 2007, they say, with capacity about four times higher than conventional batteries and of course the ability to be refueled instantly.

      I still think there's a lot of potential in recyclable computing. Where the bit bucket is wired not to ground, but to a secondary storage like a capacitor.

      Every time a 1 becomes a 0, the battery is charged.
      Every time a 0 becomes a 1, the battery is drained a bit.

      Only when the battery is empty would external power above the recycling overhead be required. I guess the question is whether this can be done while keeping the amount of energy needed for the recycling circuits below the amount of energy saved. /. did an article on this some time last year but I can't find it.

  3. Impact on the environment... by deragon · · Score: 3, Interesting

    So, what will be the impact of this kind of battery on the environment, once it is disposed? Anybody can speculate?

  4. Could laptops once again be portable? by steve426f · · Score: 5, Interesting

    With gaming laptops weighing in at nearly 10lbs. and a battery life between 50 minutes and two hours, it seems they are less than portable.

    Perhaps the Lithium-Sulfur batteries can provide a reasonable amount of time without adding weight--bringing portability back to laptops. Afterall, all of the wireless technologies are useless when you're tied to an AC outlet.
