- UNLIMITED GRAPHENE - MIT Graphene Roll to Roll CVD Explained
It looks like the days of making only small quantities of Graphene are coming to an end and soon we will be able to make the batteries that they promised a long time ago.
In this video we take a look at how the method works. - Věda a technologie
"Graphene can do everything....except leave the lab."
You could have said the same about metallic aluminum or artificial diamonds at one time or another
you could say that to silicon in the 50s
Fox Vulpes so true!

A battery the size of a iphone carrying more energy than an entire Tesla pack... I always wondered how those star trek phasers could carry the energy they needed..
Finally we know how they do
It'll never existist, anything with such a high energy density would go boom, if disrupted in any way.
All laser weapons use the same power source in science fiction. They use a micro fusion reactor that's why they never run out of electricity. Even Tony Stark's arc reactor is a fusion reactor minitarirized.
No iphone sized battery Will ever hold the same charge as a Tesla car battery.
For this, the battery has to go nuclear. There is a clear distinction between energy from transforming the atom nucleus, which is nuclear energy which is accessing the 'weak force', one of the four fundamental forces. And between energy from tapping into the electromagnetic force, again one of the four fundamental forces, which only manipulates electrons around the nucleus but doesn't affect the nucleus itself.
Hydrogen is the best user of electromagnetic force for storage and conversion of energy, particularly chemical energy to heat. Even a liquid hydrogen battery the size of an iPhone can't be enough for a car's full miles range and nothing can beat a liquid hydrogen battery.
@@arillistionis4799 Thank you Captain Obvious next rank Admiral Sure Fucking Thing.
Technology is advancing so eventually we will find a way to stabilize it.
"Never" is a strong word.
Yes, Blender needs more ads.
In my head I was listening to this video with the voice of Cave Johnson from Aperture Science. Does anyone have some cake?
Yeah, I love the aperture science references on his videos!
funny fact is...
I found the cake from Aperture science in a restaurant I go to.
Boy, I can see a Promising CZcamsr, Glad to be first 500 of the BIG Family in the Future.

Hope graphene will help improve dialysis machines and reduce sufferings of kidney patients
Is there any research done on this? I'd imagine the holes are too small
Wonderful potential for water purification/desalination, chemical production as well. Could be a game changer in developing countries.
@@alhemmings8554 Water filtration, yes. Dialysis would need bigger holes
SugarBooty but you could make graphene go in certain “moulds” and leave gaps and still be able for dialysis.
Who knows what is possible but I’m sure this will be at some point, in fact I read something I think they found how to do this basics by heating certain parts more than others and where it wasn’t heated it left gaps.
Obviously it can make it weaker etc and can tear in weak points but considering it’s still mostly in development as a material in every area this probably will be able to be done
Fantastic video and the animations were A+++. You got yourself a new sub.
Liked and subbed bro, awesome visuals btw!
I’ve been following the graphene developments for nearly a decade now.
My only question is how do I invest in graphene.
Invest in a company with a product demonstrating the use of graphene. Some company just made a power bank as a proof of concept and to prove it's viable to actually manufacture it. The youtube channel "Cold Fusion" just did a video on it.
Honestly I would hold back because most of the companies which are big enough to be publicly traded aren't going to be worth your time in the long run. The smaller emerging forms are all going to be known publicly traded or only available to qualified investors< meaning you earn $200,000 per year or $300,000 per year for a couple for at least two years and can demonstrate the likelihood of earning the same in the future.>
TLGRF
i just invested in Gratomic - a materials development company investing in graphite resources. it is a dollar stock and seems low risk for a longer term investment
Just awesome explanation .... I've been keen to learn about Graphene production .... And this video did it all
Take a look at Robert Murray-Smith's channel for how tos on making Graphene at home.
Earned a new sub love it.
I've been watching graphene since 2010 and it looks like graphene is getting ready to break out, great video!
The graphene revolution will probably be like plastic, slow. If you search around, there are already companies offering graphene products. They are not what we expect but I think we are getting there.
Thanks for the comment.
Should we invest?
Please keep watching graphene. It may get out of the lab after another 30 years.
When
@@michaelgrow9550 Graphene nanoparticles are being used in viable batteries now. I don't know how long it will take to get graphene sheets out there but Graphene nanoparticle technologies are imminent.
Why doesn’t this guys have more subscribers
Because of the annoying tonal inflections
because the majority of people on the net are from Amerikka... and have tender ears....
Because if you can't use it nobody cares.
Haha , I thought only I found his talking style a bit annoying. Enough to not subbscribe in my case.
I hope because his claims is total bullshit. Saying that Graphene batteries the size of a iphone maby can replace a Tesla battery.
WFT? That's beyond stupid.
wonderful video series, keep making such videos
your channel is awesome , thanks , love it all
Amazing!!! I subbed :))
Chemical vapor deposition...the right heat and preasure on methane and hydrogen,which collects on a copper substrate and forms a 40 ft sheet of graphene at mit. Looking forward to seeing how much they make when they upgrade their equipment and who will use it first....thanks for the knowledge,God bless the omniverse multi verses universes...everyone doing great things!
Thank you for the comment. Im actually very excite for the next few years for the exact same reasons as you. Cheers.
great vid. I SUBBED!
Great job! New sub...
Excellent!
Great video. I'm excited about Graphene uses, especially mobile devise batteries, like phones, smart watches, tablets, electric cars etc. Can you imagine a mobile phone going a whole week before charging it or putting a AA battery (made of Graphene) in to a torch that can stay on for a whole week. I think the battery manufacturers will have something to say about that.
er... imagine people in poor countries having fresh water and not dying of horrible disease. But hey you need your new toy
Great video. Very clear and concise. Your 3D animations were very helpful. Thanks! 👍🏼👍🏼😁
Excellent info and presentation, but be careful, lately we do kill the messenger ;) since 300! lol
Your 'The wonders of the Miracle Material ' animation have one free floating carbon atom (green dot not attached to anything) that got my OCD to next gear! 😂
Interesting video,thank you....
Where is this today I wonder.
I read the titles, to infinity and beyond.
Great! I subbed :)
Thanks man, I was feeling sad for only having myself as a sub! LOL
keep it up... subs are hard work these days :/
Re-entry's big problem is dumping the heat... therefore, the shields are ablative... designed to shed hot pieces.
If you make the wire using the MIT process really small like fibers the are flatted you cann weave a graphene surface and then weave at 1.1 degrees for superconductivity as you mention in your other video...weaved graphene as carbon fiber is weaved for various thermal, conductive, and structural properties ...the substrate copper can be substituted for other metals for varying properties
What would happen if our you relayered the graphene but offset the layers and pulled them through another layers larger gaps? Sort of like quilting it together.
and another question.
How they split the two elements? the graphene film from a cooper layer. what method can be used. its easy to do it and not make damge to the graphene or the roll cooper?
Apparently that is not the problem at all. From what i got form the paper, they are having trouble with the fact that the Graphene sheet roll onto itself. so its not sticky. I have to look more into this.
just compare graphene and cooper melting points.
Can you determine the orientation of the graphene Hexagons? I read in an article yesterday that the orientation pretty much determines the strength on tge graphene.
That's not quite how it works. The orientation is important, but only in the way that neighboring “hexagons” (what we call grains) need to be in the same direction for the crystals to fuse. If they are not, then the boundary will be weaker.
this video exposes your lack of understanding but it's still awesome
I was wondering why they don't dissolved the copper midway on the underside and roll it into a Brownian motion battery???
CVD, Chemical Vapor Deposition
Really nice video!!! Do you use blender for the animations?
Thanks. Yes I use blender, been using it for over 10 years.
Very interesting
In CDDA i use a CVD machine to diamond coat my zwheihander. Makes it cut a little better.
Any references for the promises at 5:17? I'm not an expert in energy storage, but I am familiar with existing energy storage designs and have never heard of anything remotely on the scale of iPhone powering a Tesla energy densities. I know supercaps are getting made with graphene, but that barely brings them in line with existing liion batteries. Sounds like bullshit so far.
With that kind of energy density in that lightweight package you could be powering flying cars, not just Teslas.
@@ExtantFrodo2 Graphene supercaps will have more energy than Li-Ion but I'm pretty sure that density claimed here won't be possible. I think he needs to vet his sources.
3:30 how the graphene domain size is controlled in R2R process?
Is Graphenoxide in bionthec and moderna and Jonson? Yes or No???
I wonder if it's possible to capture energy from craft re-entry into planetary atmosphere. It might offer some additional energy for planet side activity.
Great video, not great music. Your new videos are much better
How do we make money investing into this?
How does tis metod works?
Promising technology . Let's hope it does good on the Earth .
Graphene will change the world. Also they are working on Solid state Batteries which will also be a huge advancement. You should make a video on that if you haven't already.
Tell us when it leaves the lab.
This gives off portal 2 trailer vibes.
That was the intent but people didn’t like it. Ow well
I had Russian subtitles, but I switched saw the second time and the subtitles disappeared. Why?
Need to find a similar method to apply to Carbon nanotubes.
Looking for that as well
what about using flash graphene instead of methane??
Subbed
Interesting, though I wonder how bad people will freak out when a battery the size of and I-phone explodes. Accidents are bound to happen and that much energy stored in a small space will cause a lot of damage if released rapidly. I hope this tech comes to fruition like you stated, that will help in so many areas.
you likely have supercapacitors near you now which have enough energy to kill you instantly. your house encircles you with enough electricity to cook you alive.. but youre not dead
Do you have any information on graphene batteries exploding?
I'm not sure if I have the facts entirely clear but I was led to believe that to grow defect free graphene on a surface like copper then it first becomes a necessity to have a defect free copper surface. Is this correct or incorrect? It led me to think about how I could utilise 1~10nm copper nano particles plated in nickle to polish the copper surface with just enough abrasion to smooth out any defects but if the MIT guys have figured out how to do it using industrial quantities of copper film then that's pretty fantastic really.
Unless what they have is actually graphene sheet but which has defects but this doesn't detract from the accomplishment, it only means that with some additional quality assurance procedures they may very well have cracked the problem and that's fantastic.
From their paper, its not clear if its defect free. However they do mention that the copper was refined in order to optimize the production quality. To be honest we will eventually get there in terms of purity because there is a LOT of interest for this material, which I will talk about in later videos, so stay tuned.
I'm wondering a step further.....if a graphene belt could be utilized by depositing directly onto it, reusing the belt over and over, and simply use micro "scrubbers" to either remove all excess copper atoms after deposition but before burning, or to find another way. I'm thinking a graphene sheet as a substrate instead of copper might be beneficial.
If I am understanding your thinking correctly, if you deposited carbon atoms onto existing graphene then I would have thought the end result of this would be 2 layer graphene but separating one layer from the other without causing defect's would likely be problematic.
Can you make a paint?
Can you make a video on space fountain
Graphene deserves much more attention. There should be sheets available at every public library. Someone should publish a book about graphene with a few sheets of graphene as part of the book! This way the reader can experiment with it. Imagine a highway made of many layers of graphene. It could store solar energy and transmit it at will. A skyway strand of graphene cable could guide and power a gondola from China to California !
Go to any conference on materials. 80% of the papers/posters are on graphene. It's the only attraction everywhere.
@@enbiomatriclab Hey Thanks; that's amazing I had no idea! I am not an engineer but I wish I was! I fear that so much has already been invested in the Lithium Tech and infrastructure that Graphene will be deliberately "sat on".
@@enbiomatriclab That's interesting. Is the focus entirely on small devices or are people interested in it as a material for structures? I am particularly interested in how it can be used in composites as a filler material. I don't think we really need to perfect the properties or quality of graphene for those applications, we just need to develop mass production with some sort of process so that it is produced in the order of tons rather than mg. But this interest gets mixed in with the interest in using it as a conductor on electronic devices, which seems a totally unrelated application because in one, you produce bulk in a reactor vs the other you apply thin coats to a substrate and there is no bulk product to go to market with.
0.11 typo. It say's roll to rool in beginning graphic.
Welcome to the electro-space age !
Can anyone share a source for the theoretical capacity of a Graphene Battery?
I was trying to find some but I haven't found one quoting such an extreme improvement of capacitance (The one mentioned in the video saying the size of an iPhone can theoretically replace all 13 KWh sitting in a tesla )
I will make a video about this topic. Hold on!
you have gained a subscribed user!
No matter how much I hear or read about graphene, and how much I groan internally about how it's looking less and less likely to take over in my lifetime, I'm still enamored by the potential it has to just break things whenever it does. Like, broad swaths of tech just obsolete overnight the moment we get large-scale, minimal-defect production of the stuff and the wherewithal to do what we want with it.
Why? Conductivity is 1.4 times that of copper. Why you hating on copper? Copper is amazing. Does having 40% increase in conductivity really blow everything else out of the water? I mean copper pretty awesome already, so I don't see why we would expect such huge leaps forward by getting to graphene.
Wow, all of the batteries of a Tesla. Fit into the size of an
I-phone. That's crazy, really mind blowing.
Would finally solve the problem of an energy source for, say, an iron-man style exosuit.
All the moonlanding's control centre's processing power fit into pocket calculator.
Am I able to use this technique legally?
Yes, and technically it's not that expensive.
I would like to know what has the author of these cool videos studied when he was in school...
How did you figure the energy density for a battery the size of an iPhone that would replace the batteries of a Tesla? I thought that the theoretical maximum for chemical storage was about the same as hydrocarbons, or perhaps a small multiple of that -- not orders of magnitude greater!
definitely not possible lol
Everything I have read about graphene batteries has a theoretical energy density about 10 times that of lithium ion. In other words, this guy is full of shit.
4:02 why they use CH4(methane) than CO2(carbon dioxide)? Itis less dangerous , more cheap and i think can be more pure(the molecule its smaller)
Another question the cooper band its charged with electric curent or samething? I ask it because that can help oriented and order the carbon(C) atoms.
The reason is that it takes more energy to break the CO2 bonds but I heard that they are working on some technologies to actually use CO2.
For your second question, its not charged, but i could be wrong. What they explain is that it is a property of the copper itself that facilitates the process when heated with temperatures of 700˚C+
@@SubjectZeroScience I heard that the reason why they can't make a space elevator out of this process is because, even though it is high quality... the space elevator ribbon needs to be perfectly made. Is there not some way they could inspect and correct the imperfections to create suitable graphene for a space elevator?
Can't wait till we can roll regular thc also
Sounds interesting. When d' y' think I could buy some on eBay? Just a thought.
You can but graphene nanoparticles on ebay now. The quality varies though.
Dude, you forgot the most interesting use of this technology :
Space elevators
Space elevators are supposed to be made by carbon nanotubes, not graphene.
Wait...carbon nanotubes are tubes made of a 1-dimensional layer of carbon whose atoms are arranged in a repeating hexagon pattern.
...That's what graphene is
@@slavkosky It may be possible to create carbon nanotubes from graphene, but it is far from obvious whether that would be the most efficient way to produce them.
There are better alternatives to space elevators, that only only require materials we already have.
- Skyhooks, for example.
- Ideally: Orbital ring(s) but... there will be still some time before those are economical. :D .... like 30 years or so XD -- really, though: orbital rings are awesome ^^
@@slavkosky Carbon Nanotubes are not graphene.
How do we invest in this?
Korea has been doing this for a long time now. Good job "MIT"
Stellareffervescence source?
not bad quality for 300 sub
500 now! Cheers.
As a material scientist, I have to say the following:
- Nanotubes are indeed promising for many applications
- Graphene is a potential candidate for efficient fuel cells, so there is much research for graphene in electromobility
BUT
- Graphene (consisting of pure carbon) is one of the worst materials for applications where heat resistance is required! So the part from 5:52 to 6:12 is absolute bullshit...
Nevertheless a good video!
Hey, thanks for the comment. so would you say that First graphene Firestop is BS?
firstgraphene.net/applications/fire-retardancy/
i would like to know your opinion.
Still dont understand why your channel its not viral. In my opinion its pure quality information in here.
comments like this keep me going. lets hope it happens so i can have videos on weekly basis.
Subject Zero Science just please dont stop. I found your channel recently and I was really amazed. Thank you for your work.
growth on CZcams is usually exponential, slow growth at the start, then very fast growth.
I wonder if there's any way to get the roll of copper in and out of the gas chamber without leaking, something like pushing it through a bath of mercury (even though that would degrade the copper) such that your graphene would not be limited in length to the length of the copper roll. That way you could perhaps roll all the graphene into a pure graphene ring that could be used as a link in a super strong chain or something
Also I can see that if the copper doesn't need a seed, multiple domains of graphene would weed themselves at once and grow together. I would think there would be defects at the seams where the growing domains meet.
Both ends are in the vacuum and it unrolls from one end and rolls up on the other.
@@iamchillydogg precisely, the length of the ribbon is still limited to the space incide the starting vacuum chamber. I just thought it would be cool to be able to create an indefinitely long ribbon
Ótimo conteúdo! Mas fica no português que acho que é melhor
Can graphene be produced by laser sintering?
Yes, just not feasible for mass production.

What inventions humanity put into real life is just tiny fraction.

Good info, but you need to do a reading check before publishing. There are a number of word use errors and misspellings.
Ow, I am aware of it. The problem is that when you finally upload it, you are just sick and tired of re-watching the video over and over again. specially when you do this after work. LOL
Hurry up and figure out how to mass produce this material, I have a house design in mind.
why the guy has only 10k subs??
Because this is not a news in science and engineering community.
I think your video is great and think graphene is future in every one's life and the many products that will never rust... Cars should never rust and the steel mills might not sell much. Refrigerators and washing machines won't rust. Older cars can be fitted with new graphene parts and the age of automobiles will go up. Just replace the worn parts and interior and you got yourself a new car with low property taxes. The Tax man ain't goanna like it and the electric cars can travel farther with this light structure Graphene. Thanks for the great video and when do you think the new batteries will hit the market? Home power for you home and hunting lodge in the woods and hills. Cheaper heat and cooling. Crank up the wind mill and charge things up. The future looks bright and all you tax slaves might have an extra dollar in your pocket when you retire. But watch out those jobs out there might not make the Standard of Living. children. Teach your well.
Roll to rool? You need some proof readers. (opening sequence :)
5:10 Battery the size of an Iphone with Tesla capacity? Wow that's insane, any source for that info?
Back in 2015 they theorized that a Graphene battery the size of an iPhone would be able to power a Tesla, but to be honest I think its a bit of an overstatement but not "too" far from the truth.
Some experiments suggest, at least, a 5x the current capacity for lithium ion batteries per kg. That means that the Tesla model 3 would need a little over 1000 Graphene batteries. I know it's not the size of an iPhone but its very promising. Take a look at www.grabat.es, they are doing some really cool stuff.
I do believe though that they will be able to get at least 20x the capacity in the next 5 years. I will make a video about this so stay tuned.
Holy smokes - that would be awesome! :)
I've been reading some different forums on this topics, some just enhancing the LiIon, some changing the story altogether, and am never sure what to use a best-case scenario.
Thanks so much for a reply, you just got yourself a sub!
THat's bullshit, It is not possible. Even if you have a battery which somehow can manage to create 100% efficient electricity out of oxidation with 100% of the volume being used by the active element (and use the oxygen in the air as comburent) you will be very far from that energy density. CHemical batteries are limited by the energy in chemical bonds, so you will never go above the energy density of things like gasoline or hydrogen.
Subject Zero Science - 1:27 . . . diamond making, about one centimeter cube. WOW ! ! !
Almost
chemical vapor deposition ¯\_(ツ)_/¯
same thing yea i know
The power density claims are bunkers bro. Also, graphene is not qualified for reentry heat insulation...
Considering it barely exists that makes sense.
I think the secrete could be the extreme thermal conductivity, about 10 to 20 times of the copper. Then they could dissipate the heat with water vapor, before it could be burn in the air. But the heat energy produced is so big that even this may be impossible.
Now... they need to get SHELDON COOPER on the graphene sheet program. IT FLOWS throught the graphene.... LIKE A WAVE......
Imagine a plane made with graphene, graphene battery, graphene solar panels. That will run forever.
