Stanford Team Creates Stable Lithium Anode Using Honeycomb Film 119

puddingebola (2036796) writes "A team at Stanford has created a stable Lithium anode battery using a carbon honeycomb film. The film is described as a nanosphere layer that allows for the expansion of Lithium during use, and is suitable as a barrier between anode and cathode. Use of a lithium anode improves the coulombic efficiency and could result in longer range batteries for cars." The linked article suggests that the 200-mile-range, $25,000 electric car is a more realistic concept with batteries made with this technology, though some people are more interested in super-capacity phone batteries.

    yeah. and when it gets to 800, you'll say a 1000 and so on.

    The worlds burning, but that doesn't mean you should take a whole 30 minutes to charge up.
    When fuel is 10 dollars at the pump with a longer charge seem better? 20 dollars?

    I'd love to have an 800+ mile range but no car I've ever owned has ever even teased that (best tank ever 436miles). That being said there has been a certain standard set by the automotive industry that I *do expect electric cars to conform to or I have no problem complaining: 1 "fill" ~ 300 Miles. Your average gas tank is sized for that measure and that's a fairly reasonable amount of distance before demanding a break. I'll be a little more demanding and say I want my charge time to be roughly equivalent to my gas fill up time which is closer to 15-20 minutes. SO give me a ~300 mile range car that can charge in 20 minutes and I'll consider an electric car a viable option for the kind of long distance driving I do.

    I always found it fairly disturbing that Doc Brown wasn't able to wire Mr. Fusion into an electric motor back in 1900 (or even when he installed it in 2015!). He had the know how and the means but that would've just effed up the plot now wouldn't it have!

    Did you know there was a time in the use when gas powered cars could only go a couple of hundred miles on a tank and people managed to go on vacation just fine? That's why roads like the 66 and 80 are littered with ghost towns and closed gas stations.

    In 1973, a Plymouth station age, a station wagon got 7-16 mpg and had a 16 gallon tank. The 256 miles, BEST case.

    So I think people need to get over themselves a bit and relax about having to stop for a git during long road trips when the other 80%* is a hell of a lot cleaner. Yes, electric cars are even cleaner over all in state that use old coal plants.

    OF course, you could rent or buy another vehicle for the road trip.
    Or take a train.**
