awesome. Hope that find it's way to consumer electronics and cars quickly...
 
I've got a total chemistry-crush on graphene. So much awesome.
 
Yeah, but if my smartphone has an ultra thin graphine super capacitor, that charges in seconds and lasts all day, but is NON REMOVABLE, well... I'm going to kick up a stink on twitter. You can be sure of that.

;-)
 
Or rather I should say fun to observe.
 
+Ken Barnes I see your 10+ and raise it another 10+'s, I just hope they don't run into gridlock getting this to us like the rest of everything dealing with alternative energy. 
 
wow! wonder how long it'll take to make it into consumer products.
 
+Josh Bryson It's doubtful we'll see this in devices any time particularly soon. Other very promising technology took a very long time to make it. OLED of any sort, for example. It takes a long time to scale up production of... well... anything to reasonable and cost-effective numbers on an industrial scale. This is also in a market heavily dominated by incumbents with a history of doing things to prevent new technologies from disrupting established business models (ie: they buy the patents and sit on them).
 
+Kevin Carter you have to admit, it's good seeing this kind of progress though. I mean, we've been stuck at the same point with batteries for decades now. NiCad and Lithium Ion are essentially still electrochemical, regardless of their improvements. 
 
+Michael Lewandowski oh don't get me wrong I love reading about this kind of thing. I'm just a bit cynical when it comes to new battery tech (amongst other things) that could threaten incumbent technology. 
 
It's probably the editor's fault for writing a shoddy heading, but I don't see a scientific accident anywhere in the text, or in the original paper. But it is quite cool, the first time I've seen a capacitor with anywhere near the energy density of a battery - although if I understand power density right, I am not sure how useful this will be for most electronics, since it looks like it discharges fairly quickly and at a high voltage. But maybe I'm wrong about that. 

But I agree, it will be some time before this becomes useful. For one thing, to give a justification to turning this into a commercial technology it would have to exhibit greater energy density than Lithium batteries do today, and more importantly it would have to scale safely. As shown by the Dreamliner fiasco, the energy density of existing batteries is high enough to be dangerous (I mean, it is almost as dense as some explosives) so to scale to a higher density the material has to be easy to control otherwise we will be having more spontaneous phone combustion. The scaling and the testing of these batteries is going to take a few years, obviously, but there is always a chance it won't lead anywhere useful (such is the lot of the researcher).
