if they are designing a better super capacitor that can store more energy why are they comparing it to an electrolytic capacitor? if this is actually working at all why not just say how many joules of energy it holds.
Need to talk in energy density. Wh/kg. And super fast electric vehicle charging requires a huge storage at the station too, and massive supply. Were gunna need a bigger power station, and more transmission lines and and. Will be a very big lag between demand and gearing up supply, leading to seriously high electricity prices for all... interesting (spok accent).
Exactly, it is about ones audience. A video like this serves more as a teaser to get people intetested than to provide technical specs. Engineers will take specs like watt hours, esr, and weight, as well as cost metrics into consideration in designes that are commercialized.
They don’t tell you how many joules because most of the people watching don’t know what a joule and the number wouldn’t have much meaning. Instead they show an existing component and then say that this holds a thousand times as much energy. The audience doesn’t need to know absolute numbers because relative values convey the idea better.
i don't think leakage makes a difference when you can save 100kg off an electric cars brake regen system . as long as it holds long enough to recharge a battery
The current comercially available one have low specific energy but in labs they are reaching 100 Wh/kg. of course it is different to make it in lab and large scale commercial production but we aren't that far.
Just remember most battieries supply a steady voltage for much of their charge. Capacitors discharge curves are like a ski slope and the voltage is never the same throughout, and falls to zero pretty quick. They require electronics to regulate the output voltage.
What does oil have to do with this subject? This is about capacitors that hold energy not create energy. That brand new car that's going to be using these theoretical capacitors will still be charged using electricity created from processed oil, coal...etc.
Mishchievious Badger Unfortunately for the time being oil provides biggest supply of energy in power hungry countries like the U.S. Solar power is in its infancy and does not create a worthwhile amount of energy, in fact from all suggested its probably the worst in terms of cost and maintenance. The United States creates the most geothermal energy at 3086MW per year which is the most at 29% of the world's geothermal production but only provides 0.3% of the U.S power. Hydropower is limited, requiring suitable locations. Nuclear power is limited due to its controversy, we are actually getting rid of more nuclear plants than we are creating.
Hello NOVA, It's a great innovation, i hope to see EV's equipped with these tiny super capacitors soon. Is it possible to charge an EV equipped with these super capacitors with PV's? It'll be great if an EV have its own solar PV charger, there will be no need to stop for rechargering, even for a couple of minutes, ther will be no need for expensive infrastructure for rechargering stations. I hope to see this happen.
A high tech lab using CDs is so fucking getho I love it xD Why don't they just use a regular ass laser on two axis? (that may sound sarcastic but i'd also like to know the actual answer)
And then you realize that the patent on lithium battery technology is in the public domain, while these super capacitors are not. Aka, this wont make as much money as lithium so until all the lithium is gone or more expensive these wont exist.
Lithium is already expensive. That's why for long term high density storage they are looking at very different elements. But this is not about replacement, they have different uses. You can charge a supercap with the energy from breaking in a car. And then you can use that energy to drive again, or slowly charge it into the battery. Capacitor currents for charging/discharging are limited to the wires and the loads or sources. Lithium has very strict maxima on charging/discharging currents and recharge cycles. Capacitors have not. So to store breaking energy it's cheaper to fastcharge a supercap and slowcharge your battery with it, or just charge the supercap with the battery for acceleration and breaking power peaks.
I'm all for better batteries, but please keep things in perspective. A Chevy Bolt gets 200+ miles on a charge, a bit less than most gas cars get on a tank of gas. Charging that battery in one hour requires 60KW (250A, at 240V, 50A more than the main circuit breaker in my home). To charge it in 6 minutes, requires 600KW!
Yeah, there's no real need for faster charging, if you are charging at home, you are likely charging over night. However, where faster charging does make a difference is in regenerative braking.
At home you can charge at your leisure, while you sleep or while you work. But ultrafast charging would be handy for road trips, or for apartment dwellers who have less access to a home charger. And being able to spend a few minutes at a charger would be a good thing. Super capacitors would also let these charging stations pull energy from the grid all the time and store them for peak need. They also would be useful for power companies to handle peak need or outages.
1 atom layer thick flat super cap? they should call them Mega Caps. stack them up high enough and it might be possible to have more charge than some batteries in use and take up the same space. dont quote me on that. i know it takes a large super cap to replace your phone batter. one that one fit in your pocket. i just hope it actually works since they didn't show it...
Can you tell me if you flash the camera light to the mineral chunk of graphite that comes out of the ground, would it turn into graphene? What is the difference between the light from the camera flash and the laser beam in the CPU? Is there any special characteristic of that laser beam that turns the graphite oxide into graphene? If you hold that laser beam into a chunk of mineral graphite taken from the ground, would it turn into graphene? When can you answer my questions?
The load will self regulate... that's common electronics. What you might want to ask if you can regulate the voltage, yes we can if you treat it like a large variance input voltage.
Why stopping ?!? No Need ! You can put a Tesla Coil with a closed circuit that recirculate electricity until a Car passage doesn't brake the cycle, every few Km over already existing Light Poles on the Highway.. A receiver for the Supercapacitor on the car will be filling up the Power while on the road.. It was Already Approved by the Flat-Bread before the '90s.. You could make Graphite Oxide Being absorbed by A really Transparent Cellulose Based Aerogel and Than Lighting It to convert it into Graphene...
It's like Carbon-di-oxide, but the cheapskates gave you one less oxygen. Wait, that's carbon-monoxide... We can use volvo exhaust fumes to create it! (totally neglecting the carbon structure)
That graphene material is as black as crude oil. Very ironic. Could be there is future where people will wage wars for graphite deposits in the event of that dude DVD prints took off. lol
Volvo had car panels as battery's what happened and this tech has been around for a number of years. My guess is they are reverse engineering it for the next for years. Like the light globe that battery could in theory run for 10-20 years my guess 6-8 tops...makes you buy new battery or car
what? not all batteries use graphite. The electricity storage of super capacitors isn't from static electricity, electrostatic forces only facilitate molecular adhesion. The capacitance of one of those "graphene" structures put onto the CD is 0 and they wouldn't work as capacitors without a lot of other work needing to be done first like housing, development of the circuit, etc... Just laser printing some carbon onto a piece of plastic doesn't create a capacitor and it certainly wouldn't even come close to the capacitance of those electrolytic capacitors since it's missing that ever so important surface area. They even talk about it in the video where it describes how just a few grams of graphene could be made into a single sheet the size of multiple football fields. What they printed on the CD doesn't look like multiple football fields to me, unless those were super special giant CD's with giant aliens doing the recording/interviewing.
I think in every sense. Four elephants can stand on top of a needle pressing down on one layer of graphene and it wouldn't puncture- or something to that effect. It may be possible to use it for a space elevator because it's that strong. No other material can be used.
And the US military would love to have these super capacitors to power the next-next-next generation of electronic combat rifles. Imagine a super capacitor the size of a regular rifle magazine that that powers a rifle that shoot down airplanes at 30,000 Ft or kill an enemy at up to 10 miles away at the speed of light - silently! Can you imagine an enemy leader standing up on a platform speaking to thousands of their followers and then without a warning they suddenly slump down and fall dead without a gunshot or explosion being heard! Then on closer examination of the still twitching dead body, there is a smouldering 1 inch circle in their forehead that went through their head and also burnt out other materials behind them as they stood speaking. The area reeks of the smell of cooked flesh from the now deceased leader. The enemy leader was killed by a high power laser rifle from 10 miles away with a 0.3 second burst of laser energy that was totally silent and invisible to the naked eye. Only some one who had the latest Infra red scanner who was looking at the subject at the moment of death may have caught that 0.3 second of heat from the laser as it traveled at the speed of light. One moment they were speaking normally, the next they simply froze up as if they were momentarily stunned, and then they fell lifelessly to the floor dead but with the trail and smoke of the cooked flesh and brain matter oozing from the head wound. Its a very scary scenario, but I really believe the tech is already here.
Energy density. It sucks more for capacitors than it does for batteries. Also the energy imput compared to output sucks for both. This video talks bulkbullshit.
Only thing wrong with this video is that it was too short, I wish they showed those capacitors actually holding a charge.
They are commercialized now.
Thank you NOVA, this is why I love PBS
I'm glad someone finally found a use for LightScribe
if they are designing a better super capacitor that can store more energy why are they comparing it to an electrolytic capacitor? if this is actually working at all why not just say how many joules of energy it holds.
It's about getting investors, grants, and funding. ;)

The claim that that printed circuit would hold more charge than one of those electrolytic caps was bullshit; that's why.
Ingenious way to make graphene! How the hellhave I not heard of this method until now? That graphene revolution is finally here!
this is amazing. good luck guys, i hope you figure out how to implement it on a larger scale soon
It's amazing what people create. Humanity has hope after all.
They didn't talk about leakage which is a huge problem for capacitors. I wonder if this technology has any advantages when it comes to leakage.
i don't think leakage makes a difference when you can save 100kg off an electric cars brake regen system . as long as it holds long enough to recharge a battery
Why can't I find any papers on this? Ohhh 🤔😂
...ohhh what? What's your point?
Wosshhh
What is the energy stored per pound of this compared to a modern lithium battery?
Best today have 5.5Wh/kg, and the best Li-Ion have 240Wh/kg.
The current comercially available one have low specific energy but in labs they are reaching 100 Wh/kg. of course it is different to make it in lab and large scale commercial production but we aren't that far.

these 5 dislikes must be oil worshipers....

I dislike because NOVA cannot do a proper audio equalization before upload, even a monkey can do it.

Those printed patterns look more like inductors to me. How the hell can that tiny structure hold that much charge?
It has a carbon foam structure with a lot of surface area.

You won't see that on cars 😂😂😂 you kidding me.
Those circuits printed on the CD will most certainly NOT hold more charge that those electrolytic caps he showed.

Inversion drive is supplemented by infusion drive! Our friction keeps us moving!
Electricity? I am still using my kerosene lamp.
im still using primitive torches to light my cave.
Lol
It is possible to make a capacitor to charge a bus or car betrries in a few seconds .......
???
Patel Naman it will be.
graphite isn't the strongest material, carbon nanotubes are.
Neither graphite or carbon nanotubes ars the strongest.
Graphene is the strongest material.
Why this is technology is not commercialized yet?
Why stopping ?!?
No Need !
You can put a Tesla Coil with a closed circuit that recirculate electricity until a Car passage doesn't brake the cycle, every few Km over already existing Light Poles on the Highway..
A receiver for the Supercapacitor on the car will be filling up the Power while on the road..
It was Already Approved by the Flat-Bread before the '90s..
You could make Graphite Oxide Being absorbed by A really Transparent Cellulose Based Aerogel and Than Lighting It to convert it into Graphene...
Wow... battery super fast charge thats all i heed
How you print it to cd
And now it is being commercialized.
Boston Dynamics uses this to their robots
"Graphite Oxide"
its hard to think of it as carbon rust but its just bonded with an oxygen atom. the cd drive laser converts it pure carbon graphene.
It's like Carbon-di-oxide, but the cheapskates gave you one less oxygen. Wait, that's carbon-monoxide... We can use volvo exhaust fumes to create it!
(totally neglecting the carbon structure)
Where is the increased surface area....damn it man.
Is graphite attracted to the magnet?
No
charged in minutes, also discharged in minutes...
Burning graphite results graphene oxides?
That graphene material is as black as crude oil. Very ironic. Could be there is future where people will wage wars for graphite deposits in the event of that dude DVD prints took off. lol

Coming to the public with this development will drive the petrol tycoons to kill this progress
1:00 stronger in what sense?
I think in every sense. Four elephants can stand on top of a needle pressing down on one layer of graphene and it wouldn't puncture- or something to that effect. It may be possible to use it for a space elevator because it's that strong. No other material can be used.
Is this graphene? Bcoz graphene is single molecule of graphite so it is transparent.
A fractal pattern would provide much more surface area than those rectangles.
Uau
I have need
Unless it's batteries blowing up or new batteries being used, I don't like these battery innovation stories that get your hopes up
3 year old video and still no sign of graphene ... Hmmm .
rolling graphene one atom thick 20 million times round should make your super battery this tech is 20 more years away
thats sooo much voltage though. instead of static sparks igniting gasoline a spark the battery terminals explode your arm. muscles, bones and all.
And the US military would love to have these super capacitors to power the next-next-next generation of electronic combat rifles.
