Stanford Team Creates Stable Lithium Anode Using Honeycomb Film
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.
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.**

Except that you have bought them; you just haven't realized it. Energy density of li-ion batteries has grown by about 50% in the past five years. Have you seriously not noticed how cell phone and laptop battery mah ratings keep growing while they keep making the volume available for the batteries smaller?
It's big news when a new tech happens in the lab. It's not big news when the cells first roll off a production line.
Most new lab techs don't make it to commercialization. But a lucky fraction of them do, and that's the reason that you're not walking around today with a cell phone with a battery the size of a small brick.
It's a Cyrillic alphabet. It's like all those keys you never push on a calculator.
This. Compare today's cordless tools to those of the late 90s. Night and day. The battery revolution has been going on for years, but because it didn't happen overnight nobody's noticing.
I expect Slashdot to trumpet every potential battery break-through because it's new for nerds. I don't expect to find those new batteries on the shelf tomorrow because I'm not an idiot. It's a long road from the lab to the market, most brilliant ideas don't make it.
Never let a lack of data get in the way of a good rant.
