Awesome (Super) Supercapacitor!

I remember watching a documentary about the guy who discovered graphene and was amazed by the possible uses that it potentially had. It's definitely going to impact the electric vehicle industry in a big way. Also, standard batteries that we use now will become obsolete. We'll have a greener more efficient and quicker way to charge our devices. Seems to tick all the right boxes.

I just love the idea that you would drive into a charging station, plug your car into the plug for the same amount of time it take to fill up with petrol, then go for another could have hundred miles. Also in the way of phones, and other battery powered devices, plug it in for under a minute, and its charged for the whole day!

I especially like that its completely made of carbon, so can just be composted, and returned to the carbon cycle! :D

edit: The real question is though, how expensive/practical will it be to produce on a mass scale for consumers?

It should actually be very cheap because unlike conventional batteries you don't need the cadmium, lithium etc. which are costly to produce. It's also biodegradable so need for expensive recycling.
 
Your forgetting the hard bit.

Generating the electricity in the first place is one, (another 4-5 Nuclear power stations would be required minimum) and which is the main factor the lack of income the Government receives in tax from OIL. People think electricity is expensive now wowzzzerrrs.

Yeah, I for one am a bit afraid of the future, regarding electricity.. Correct me if I'm wrong, but we aren't really prepared for when the oil does inevitably run out. The thing I think I fear the most is the blackouts, where almost nothing in society can function.
 
If we stop spending money on oil to fuel our vehicles then that money saved can be spent on providing more electricity. Swings and roundabouts.
 
Its not as good as it sounds.

Batteries are still the way forward, we already have toshiba Scib batteries that are extremely fast charging and many battery prototypes that are two-ten times current lithium ion batteries and can be charged upto 5x faster.

So a graphene supper capacitor that can just about achieve current lithium ion isn't great and can charge at double the rate of lithium ion.

Cost looks like it could be good.

However graphene is great as is being used in many of the prototype batteries.

Not going to happen, lost revenue at the pump = greater electricity prices for everyone, regardless if they drive or not.

Mass EV will happen and it is very unlikely to change electricity prices as that would screw up the economy. The far more likely outcome, is vehicle tracking via camera or gps, and charged per mile.
Just like France is going to introduce in 2014 for vehicles over 3.5tons. Which is going to **** haulage companies up, as they have to fit a gps tracker (regardless of registered country) that is rumoured to cost around €1000, then €0.09-0.15 per mile depending on road.

It's a new technology. Like all things new it needs to be refined and improved. I see no reason why, given investment, grapheme super capacitors couldn't supplant current battery technology. It's just going to take time to develop the technology and the manufacturing process in order to make it economically the practically viable.

Its already worse than the prototype batteries though. So yes there might be niche markets ie cost sensitive ones, if it turns out it can be mass produced for cheap. But it really isn't the future he says in the video. The prototype batteries can charge faster and hold more than the prototype graphene capacitor.

Sorry, what are you referring to ? Can you link me ?

This is from the link you posted:

These graphene supercapacitors could really change the technology landscape. While computing power roughly doubles every 18 months, battery technology is almost at a standstill. Supercapacitors, which suffer virtually zero degradation over 10,000 cycles or more, have been cited as a possible replacement for low-energy devices, such as smartphones. With their huge power density, supercapacitors could also revolutionize electric vehicles, where huge lithium-ion batteries really struggle to strike a balance between mileage, acceleration, and longevity. It’s also worth noting, however, that lithium-ion batteries themselves have had their capacity increased by 10 times thanks to the addition of graphene. Either way, then, graphene seems like it will play a major role in the future of electronics.

There's litterlay dozen, but if you read the article I linked

http://www.extremetech.com/computin...ion-battery-capacity-and-recharge-rate-by-10x

Grapheme supconductor is capacity of current high grade lithium ion and cna charge twice as fast.
Well pretty much every single protoype out does that and some by a large margin.

Even the toshiba Scib battery that is available on the market outdoes that.http://www.scib.jp/en/

Honda and another car manufacture will be releasing EV cars this year with Scib batteries that recharge from a standard wall charger in ~3hrs due to the constraint off the power delivery. If they fitted a faster charger they could charge even faster. But they aren't fitting them with fast chargers due to battle of standards.

Sorry Glaucus but I don't see what you're getting at. Your own links say how much more efficient graphene batteries will be compared to current lithium batteries. What exactly is your argument ?

Read the paragraph about it matching current lithium storage and charges twice as fast, then read the last paragraph. Then also read the info about toshiba scib batteries.

Current batteries is not the same as protoype batterie. That is also ignoring the toshiba scib battery which is already available.

The Grapheme superconductor is a protoype and is massively outdone by battery prototypes and is matched by toshiba scib which is already available.

In other words you got a future product that is far worse than alternative future products, so its not going to change the world and it isn't going to be extensively used.

Someone didn't watch the video in the OP. :rolleyes:
 
Glaucus said:
Yes i did, and that doesn't change anything at all.

So what in the video goes against what I've said and the article i posted says?

How about the potential to charge your electric car in a few minutes and your devices in seconds. :rolleyes: Can current batteries do that ?
