#2… store 10 times more power…
…after 150 charge/discharge cycles, is also five times more effective than any lithium-ion battery currently on the market
Is this the positive way of saying they lose half of their capacity after 150 cycles?
Ten times capacity is certainly a game changer for everything from wireless ear buds to electric cars, but * week-long smartphone batteries within a couple of years* sounds optimistic for something that is fabricated at the atomic level.
What exists on the market now that is designed at the atomic level and mass produced?

Silicon chips?
FWIW, the holes are created using 'a chemical oxidation process' -- which I suspect can be done on a large scale. If someone can read the actual paper and check out how they made the holes, though, that'd be cool.

#4Seems to me that if this proves out, and can be made affordably, the most exciting application would be electric cars -- no more range penalty vs. gasoline. Anyone know enough to comment on the likely applicability?

mmmm electric cars... 10x the range of current cars... thats what... cross country in one charge? can anyone argue with that? Ok fine 10x is not cross country... but it is 2000 miles per f-ing charge!

I'd rather have 200 miles and lighter/cheaper(? at least in terms of environmental costs) batteries.

In environmental costs, I'd much rather have FeNi chemistry fully explored. Nickel iron batteries can be abused by under and over charging, short circuiting heat, cold, vibration, and other effects and still last decades.
Jay Leno has an antique car that still has a working FeNi battery. I think it needs topped off with distilled water every so often. The electrolyte is KOH so it even acts as a preservative. The only problem with the reaction is it's slow to charge and discharge.

#8So how long do you reckon we will have to wait for something like this? I'm still waiting for lithium-air batteries from MIT http://web.mit.edu/newsoffice/2011/better-battery-storage-07...

#9This would be a real game changer for electric cars. Even a "mere" 3x enhancement would already make them really competitive with combustion engines ones, but with 10x they would just be better than our traditional cars. Let's hope this technology can be industrialized in an economic way.

#10What is the safety of this battery? At 10x power we are looking at potential explosion for eletric cars instead of raging fire for gas cars... Does it work in 30 below zero?
