  1. A new take on battery technology could mean that we'll soon be able to charge our device batteries twice as fast as what's possible today. Engineers at the University of California, San Diego have developed a new charging algorithm that...

    Great! Tesla should implement this.

    I thought rapid charging is bad for lithium based batteries, decreasing their capacity. A slow charger is better, from what I understand. So does this mean a battery could only last as little as only 6 months or so?

    No, this is charging faster without reducing life span. They are predicting where the uncharged particles are and essentially targeting only the uncharged particles with electricity instead of wasting time by have electricity flow more randomly throughout the battery.

    This is cool, but really I'm waiting for some game-changing discovery in energy capacity. I want to be able to use a core i7 type machine for a week straight without needing a charge!!

    ...if only
  7. Probably they know this from `90s but now they are aloud to do it.

    If an editor reads this, there is a bug with the comments. It says that the comments were made 3 months ago, should be hours ago.

    Should improve it then?
  10. This is great. One of the most important aspect that hasn't improved in par with the strides of recent mobile device hardware is the battery life.

    Waiting for the day where we can charge once and use a smartphone for 1-2 weeks without recharging. That is imperative!

    actually, we've found it, but still in research (still in prototype)

    This will also reduce the size of the battery or same size battery can last to longer duration.

    Why test it in electric cars though? I would rather my Phone could last longer and I'm pretty sure if this kind of tech can get into phones first that would please a much bigger crowd than the few people who wasted money on an electric car.

    Try and check your local computer's clock - I am not an editor, but the date and time counters change if you change your clock.

    It's probably going to attract more investment dollars from automotive manufacturers who are looking for improvements in this market. Consumer device manufacturers might take an interest, but I'm guessing that there fewer R&D dollars from these guys.

    catch 22. Fewer buyers (like me) because either the range is too short or the charge time too long. I need 2hrs duration and about a one hr recharge time - - and boy I'd be all over an electric car, showing big oil where to stick it.

    The reason I say that though is because well electric cars appear to be doing more damage than that of a standard car:

    Surely starting small and then going big is a better idea? but I guess your probably right, the money is in the car industry I guess?

    My point is the savings benefit to the consumer is the auto industry. Certainly, longer battery life is a boon for all such devices:)
