So 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...

Re: Graphene improves lithium-ion battery capacity and recharge rate by 10x
#12… 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 optimisti…

#14This 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.

#15What 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?
So your concerns about safety are fine - this should only be as safe as any other Lithium-ion or Lithium-polymer battery.

#16Seems 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!

It'll surely be patented and sat on for a while at a very high price. My bet is we'll need to wait $time_of_release + 10 years until we see things working out over traditional cars.
On the other hand, if the technology required to mass produce this kind of batteries will be too new, it could take time to scale it and bring costs down. Let's hope it isn't too innovative.

#19Or a notebook that didn't need all the power management to dial down the CPU and GPU when unplugged, and could barrel away full speed and still last for a day or two. You'd still have to worry about heat dissipation, but there are plenty of fast notebooks that handle that fine when plugged in.
Or an iPad with the battery life of a Kindle. Or a Kindle that you charged once a year.
