Reuters has another one of those new battery technology stories (and, yes, it does contain the word nano.)
What makes this more interesting is the Israeli firm in question has a number of high profile investors including an "Asian Phone manufacturer" and the owner of Chelsea football club. They are also talking about a product in 2016 rather than the usual 5 years' time.
I am not convinced by the extrapolation up to car batteries as you'd need a very thick cable.

I feel like I'm in a Toilet Bowl with a thumbtack in my forehead!!

Wake me up when they provide information about the advantages of this new technology in the capacity/weight ratio. This has been the main "show-stopper" of the batteries for decades - for cars, mobile devices, and so on. Recharge speed is important in some cases, but not all.

Indeed, even for laptop batteries, I'd prefer one which I charge overnight and which then powers it for two weeks over one which I can charge in a minute but which is empty in a day.

Well for automotive and phone use, clearly recharge time does matter.
It probably matters more than some modest increase in weight.
You seldom see anyone complain about the weight of their cell phone. In fact the term "feels good in the hand" has become a standard catch phrase in cell phone reviews as a stand in for heavier than it looks.
Most people are happy with a phone that gets them comfortably through one day with a few hours of reserve.
Most drivers think an electric car becomes practical when you can drive as far as an ICE car will travel in one day.
But people quickly see through the requirement for an hour long charge after the first 200 miles just to achieve the next 100 miles. Or never daring to pass an electric outlet with your rapidly depleting phone battery.
Stop making my phone thinner and lighter. Double the battery please.
And 265 (optimistic) miles in a Tesla doesn't even last till lunch stop.
For practical use, short charge time trumps weight in just about every case.
No, you are mistaken. I've always had this sig.
