Mesoporous Graphene for Lithium-ion batteries [2020]
Graphene has a theoretical capacity of 744 mAh/g with outstanding electronic mobility at 10,000 cm2/V and extremely high lithium diffusivity at 10-7 - 10-6 cm2/s, it holds great promise as an anode material for high-energy-power lithium-ion batteries.
But the problem has always been producing high quality graphene sheets as we know that any defect will decrease the electric conductivity, electrochemical and structural stability which in turn has a negative effect in power density and Coulombic efficiency.
So far tests conducted with graphene yielded unfavorable results due to how difficult it was to produce high quality sheets, but in this research, titled High-quality mesoporous graphene particles as high-energy and fast-charging anodes for lithium-ion batteries, they were able to improve high quality sheets yield by chemical vapor deposition using a mesoporous Magnesium Oxide as a template and catalyst to start the process and adding an additional step with microwave radiation.
They basically grew nitrogen-doped graphene within the pores of the Magnesium Oxide template.
The idea is straight forward, you have a structure full of holes whereby using chemical vapor deposition, the nitrogen-doped graphene accumulates in these pores reacting with each other and turn forming a graphene sheet, all you need to do now is to submit the structure to an etching process to chemically remove the Magnesium Oxide template.

NOTE: The animations in my videos take a substantial amount of time to make, so please be patient. I am trying to get a video per week, but some times it takes longer. - Наука та технологія
Graphene the substance that can do almost everything, but not leave the lab...
It’s already left the lab. Real Graphene is producing batteries that are available for purchase right now.
@@theflyingwelshman5338 yes you're right but they are only graphene enhanced which means it will charge faster but doesn't have capacity as graphene it's like lithium batteries with graphene on top..
Graphene is bullshit, I only believe it when Elon Musk says it
it's like vibranium, it can solve all the problems the plot throws at us..
It was also put into use earlier on by a company making bullet proof clothing for the rich
Nice! I can see you've started to incorporate the suggestions and requests made by your subscribers. You value us. You value our suggestions and requests.
You are good man.
This channel is so severely underrated
Good. Keep the idiots competing in the comments for comedy at other pages
deserves more attention
@@asmrgamingOz Totally..
@@FrnnkEducation I wish one day you explain your work flow.. Especially the animation part with blander.. Also your hardware and video software. Your work is great, It really takes time but it's worth it.
Thank you Subject Zero. This channel should have way more subscribers for the value of the content and animations. Always a pleasure to watch. The pace of the voice is excellent. I always chuckle at the sign-off. Thank you. We're done here 😀
Seems your channel is going quite well. Congrats my dude hope it continues to grow
*Their trick was* to heat up the Graphene in the microwave :-)
Baking oven, and steam cooker next !
the way you visually represent data is so nice to look at and your voice is great, one of my favorite channels
So you're telling me if I microwave my phone, it will renew the battery capacity? I'll give that a go, thanks. 1000W for 5 mins.
Probably try to remove the battery other things can get destroyed.
Rob the carbon out of your battery and whack that into the microwave.
The resulting fire should be fun especially as your phone now can’t call 999/911
U alive
@@aspirant0009 F
@@zerotwo_.002 remove the battery and then microwave what? if there's a metal case on the battery, gently take the battery out and maybe add some lithium and graphene. i wonder if salt and pepper is close enough?
Just sitting here trying to act like I know what he is talking about.
It makes me look good when my bro passes behind me and peaks over my shoulder
6:06 me right now
you kidding me? the way to fix the defects in graphene sheets was to stick it in a microwave?
My guess is it's kind of like re-joining together the broken areas similar to re-heating chocolate squares that cracked.
As graphene is conductive, I would guess that the defects create resistance. The microwaves I would assume create hot spots at these locations breaking the bonds, as the sheet is charged from the microwaves again assume that the carbon ions are attracted and arrange to the lowest resistance configuration.
Dude this is gonna become the future go-to tech answer along with turning things on/off. "Have you tried putting it in the microwave yet?"
is it safe to put the graphene in the microwave with my hot pockets?
That should be one of the default tests in any research - just put it in a microwave to see what happens.
This is incredible! I've been watching the progression of graphene for years, it's prospects always seemed so great but out of reach. Can't wait to see this highly efficient tech in phones / computers / cars! Thanks for the explanation vid!
What a great channel . Wish I was back at Penn State hitting the bowl with my chem buddies in the 90s
with this entertainment. We just had a white board and TOOL.
I love the quality of your videos, also the animations are always great :)
just found your channel. It really seems to be an unrealized (by subscriber numbers) resource! Thanks for sharing your insights and information! (just noticed.... you're from CANADA too? EXCELLENT :) )
As always animations and graphics are top notch.
Thank you for tracking this topic and providing outstanding information.
This is one leading edge science channel on UA-cam. Subscribed!
You are awesome. Thanks for describing the details so thoroughly. I love this channel
Love the animations. First time here to your channel
Hi! I'm doing a senior design project where we took a look at using silicon anodes for batteries due the high theoretical capacity like you mentioned at 4:47. The main issue is that during the charge/discharge cycle, the silicon has huge mechanical stresses as it is subject to volume expansion of up to 400% so it has a lower capacity retention. The solution seems to be to use silicon nanoparticles. It is very interesting to see a sister project on how to increase the capacity of batteries. I hope you do well on your channel!
Found your channel yesterday, I love how you put the wild claims of science journalism to the realism test. Aside from science, I love that you say "Alright folks, that's it, we are done here" at the end of every video. It was kinda weird to hear at first, but it adds character to the channel.
At 8:06 you seem to be comparing statistics of an entire cell against just the graphene material, this is very wrong as you include the weight of the packaging (and steel is heavy) in the battery, and not in the graphene. This is extremely misleading and makes me as a battery researcher a little sad. Also at 4:31 you forgot the h in mAh/g. But thanks for the beautiful graphics.
but we want to consider the wall too don't we,
@@theunknown4834 Yes on the consumer end you do want to consider the packaging, but you can't compare an entire battery module, packaging and all to, to another battery system when calculating energy density. Aside from that, including inert material in the calculation is misleading. I've only read a few materials chemistry papers, but it seems to be the convention that the efficiency calculations obtained in a lab environment are often ideal and can't be compared to a consumer unit.
aMasheep. I would love to hear you teach. A guy really in the field, rather than a UA-camr.
@@VyvienneEaux I think that also highly depends if the development of graphene can yield more of the packaging useless. Right now, the biggest issue with batteries is their size and weight, which is mostly due to packaging that robs space and weight of the actual battery itself. I'm not as intricately educated in this field, but if graphene helps with that process then it should definitely be considered in the overall statistics.
MISTER SIR
Electrons and ions take next to no space. The issue is how many you can pack into the carbon anode. Pack it too full and it literally expands. Add in heating, cooling and lithium metal deposition and the anode falls apart all too quickly. Graphene might provide the larger surface area needed to not have to pack ions literally into the anode. Alternatively, graphene might be flexible enough not to fall apart.
This is cool, I just cited this literature in my paper at UCLA. Spot on analysis.
Wow, these videos are really good! Subscribed.
Finally something that can catch my eyes. well done. Wow all the animation done in blender Eevee your are great.
Salivating at what I could do with batteries like that in drones and RC stuff
I love these videos bro keep up the great work. lol when you took that breath 2:25
Finger crossed for future of graphite.
Thank you for your video.
I really appreciate your beautiful work! Thank you, Subject Zero Science. :)
graphene in LiPO batteries, even kinda crappy ones, is fantastic. Hobby/RC batteries are building a lot of momentum because they can be recharged at 3C without lifespan reduction, and they don't sag until you've truly used 95%+ aH
Love these smooth blender animations
Four times the current storage capacity sounds pretty awesome. Being measured in terms of mass, a reduction in the amount of mass and retaining the same energy storage means vehicles that are much lighter. The current Tesla is 540kg (1200lbs) of battery mass. a quarter of that mass should yield some significant improvements in mileage.
Great video. Thank you for the brilliantly presented material and concise information. "The future is here" indeed! This opens great technological improves.
Concise, but not layman friendly
you’re my favorite channel
A 2020 update, sweeeet!
Please do community post update for graphene updates that you're not covering in your video.
Thañk YoU....
You're doing great work...👌
Subject Zero : I am improving the graphics
Me : This video is a slick boi
Beautiful graphics! Thanks ;-)
Your logo and copyright on the video look a lit better now ! Still there but nice and subtle
Good show. Subscribed.
Yess! so looking forward to this I'm commenting before even watching.
But what is your comment about ?
God dammit when i'm done with my degree in materials science there's gonna be nothing left for me to research with Graphene..
Not at all. Getting manufacturing processes explored and prototyped for full-scale/high volume 3d graphene (as in actual solid forms) while retaining the strength of graphene as predicted (5-10x the same thickness of carbon steel) will be hugely important.
I get the impression Graphene has a lot more to show us as it becomes commercially viable
Then you do not understand research yet. Counter intuitively, the more experiments you do, the more questions you get. Soon you realise that you need 3 lifetimes to figure out a small s niece of the properties youre researching. The funding might dry up thou.
Go on and work on Graphene 2 then
Graphene may be it's own industrial revolution. Relax, your sounding like the head of the US patent office who around 1900 said everything patentable has been invented and that we should dissolve the patent office! You will make great discoveries!
6:42 vanilla ice ice baby🤣🤣🤣 lol looked through the comments and I'm the first one to notice it
🤣
Cream
Impressive. Now to move it into production.
"All right, folks. We're done here."
I see what you did there, Cave.
Nice work sir.
What modelling software do you use for this videos?
really nice visuals btw. Hoping for more views for you
omg how these slides are made? such a good quality
Imagine some dood was making ramen at 3am and he just happened to grab the wrong box on the desk when he put it in the microwave
Well one of the first single atom thick graphene production patents is the Scotch tape technique, soooo I wouldnt be too surprised.
Wake me when these battery tech breakthroughs become a mainstream consumer reality.
Can you give us the title of the background music you used from 00:05-01:01? I find it very soothing and perfect for work. Thanks and keep up the great work! I always enjoy your videos, although I sometimes need to rewind a few times to really grasp what you just very thoroughly explained... 😅
Great video. Which companies are producing this?
Awesome thanks!
I feel positive about the future now!
Nice one. Thank you!
Pretty informative - when do you expect this to come out in the market in mass production? I am waiting for Electric Planes.
You deserve more subs
What is the latest news on the lithium-sulfur batteries? Love the post. Thank you!
Looking for your video for a long time now. Great work, I'm waiting for you to reach a Mil
Nice naming scheme for the paper!
Real intuitive and easy to remember
A lot we don't know... I am still stuck on how the heck a 1.1 degree angle in alignment can allow superconductivity. There has to be some principles we are missing! Great about the battery tech : )
Given the relatively minimal difference between the low quality NMG and its higher quality counterpart, I'd go for the former at first so as to get the economy of scale going for NMG anodes in general.
2:14 => 2:21 - Loved every second of it :p
Keep it going dude
Just a thought I am sure has been tried etc , but what about a way to make larger sheets then cut out with whatever process might work (laser , chemical etch etc ) the areas of the sheet that have the lowest imperfections or possibly no imperfections ? Alas the imperfections are probably fairly uniformly distributed in the material. Interested to see if something like this has been done to obtain some useable amount of essentially perfect graphene at least for experimentation and getting an idea of the maximum practical capacity of batteries using this material.
Can you also please make a video on PHA from food waste, industrial technology
would appreciate understanding how the mining of graphite is going to affect the industry - ie Gratomic INC
Wasn't there a video about Electric Airplanes released? Was it removed?
Spectacular
Don't talk bad about your early videos it's what brought you where you're today.
Thank you.
amazing video
Incremental improvements in fabricating high quality graphene sheets are great, but when will we see it in production on a large scale? Until that happens, you'll only hear about it on UA-cam videos every few years.
- You didn't see graphene.
- I did.
- You didn't. YOU DIDN'T, because it's not there!
Are you suggesting graphene doesnt exists because you cant see it? If so, that is incredibly stupid..
@@Vatsyayana87 Do you know quotes from HBO Chernobyl?
Nitrogen-doped graphene. Now that just sounds cool af.
increased capacity means lower price and better performance. Simply because a lighter smaller battery can replace the current one with the same output except the car is lighter and roomier overall therefore becoming more practical. Also charging/discharging speed is important adding to the practicality of the resulting vehicle.
2:20
Loved it
Battery development is one of the biggest civilization game changer at this moment. High capacity batteries will change the world and enable our civilization to solve major problems. A big amount of money should be poured into this technology even more than fusion reactor projects...
exactly
I had thought that MIT had figured out how to make high quality sheets of Graphene a year or two ago
MIT intentionally scuffs research to discredit certain fields, it's an old CIA method. Their production method for hq graphene was unreasonably expensive. They also tried to kill ionocraft by using the least optimal methods - high voltage corona discharge and thin wire cathodes.
ill add this to the list of the batteries we'll never see
Is this method of production scalable for industrial manufacturing?
The future looks bright for battery development. But the crucial question is how far in the future?
have they tried quasi crystal patterns in the sheets yet ?
Battery technology is still at stone age phase!!
I'm really wondering how one of your video's would look like, rendered in Cycles or AMD ProRender for Blender
Wow.⚡Amazing.
This could be world changing, 10 years from now and we could actually have feasible renewable power grids to support base load.
That's really just a matter of cost per kWh. Where energy density has the biggest impact is electric aircraft, which will probably be a really big deal in the coming years due to the dying jumbo jet industry.
What dekutree64 said. Also the future of grid scale storage most likely lies with flow batteries.
Thanks
A multi layer graphite sheet set upon the differential where the problems are and how the world will change .
At 9:32, the numbers indicate both batteries performed BETTER after 500 cycles than as new.
Damn! It's getting close. -Combined with ever-increasing efficiency in our devices, we're going to be in a very good place wrt battery life in a couple of years.
I actually think it's good that it's taken so long to develop good batteries; it has forced engineers to become masters at efficiency. -Like in the old days with home computers; You'd have a C64 in your rec room for several years, (for instance) and when you wanted to boost things, you couldn't just go out and buy more memory or a faster GPU. It came down to software engineers having to really perfect their craft.
He's blinding me with science!
18650 cells come up to 3600mAh for some Panasonic NCR cells.
The first slide was a bit wrong because we can easily buy 250-280 Wh/kg, although you are right that in the next 10 years it's likely we will hit the 350 mark and by 2050 we may be at 450 or 500, which would be twice what a tesla uses, although, look at solar. billions of dollars invested, performance has never risen in massive leaps, just small steps since the 1990s, from 12 to 25 percent, that's like, 1-3% per year.
Beautifully made video! I love the anymations. Unfortunately i die not get the C or the mg/cm^2 😅
The dislocations a also problem for people who want to study them for other applications
That's exactly what i was thinking.
ICE is important for the future of transportation - Initial Coulombic Efficiency.
Btw, the symbols for watt-hours and ampere-hours are W⋅h and A⋅h respectively, not "Wh" and "Ah". The multiplication dot (or sometimes, a space) is required. Also, since you're a science channel, I'd recommend using the proper SI units of joules (J) and coulombs (C) so that you can avoid having to type the multiplication dot and use proper units.
3:27 Heeeeeey! Your vids are not shitty!
