We show how to make an ionic liquid from simple components and construct rechargeable aluminum-ion battery. Future artificial muscles could be working with ionic liquids. We make ionic liquid supercapacitor using carbon powder as electrode material. Electrodes are roll-pressed.
Synthesis of aluminum chloride - urea and EMIm+ AlCl4- ionic liquids.
Other ionic liquids: EMImBF4, EMImTFSI, EMImOtf.
There is one mistake - ionic liquids are non-flammable (word inflammable is used in the video).

@chemicum
Fantastic! You can tell how much work went into this short video!
true
I am amazed to see how easily you can make functioning batteries and supercapacitors. Thanks for the great video!
It was indeed surpisingly easy to make that rechargeable aluminum-ion battery.
Very nice deep dive on ionic liquids! And amazing computer simulations!
This is the Best channel ever seen for diy battery and super capacitor.
Amazing video! Always had been fascinated by ionic liquid but couldn't find much good documentation on them :)
Yeah, there are no other other videos of actually making one
This is amazing! I've never seen ionic liquids being made in this much detail.
Good experiences. I also like to spend with batteries👍
Very good video. Good information
Excellent presentation. I have been playing around with ionic liquids for awhile but always struggled finding good information on them. This video has some great information and is a huge help for me! Thanks so much for posting this.
Great representation of how ILs can change the future of battery technology. kudos!!
excellent...from Chile...!!!!
Cool, thanks for the video!
Awesome information..Keep the great work up..5 stars *****
Really great work, glad I found your channel.
Fantastic
Very interesting and informative.
Increíble video. Apenas estoy sumergiéndome en el tema porque voy hacer una tesis sobre esto y me ha encantado,
Wish u a Happy new year sir 2022 from India. Subrato ..ap ... Xrox .....good usable vedio sir
yg benar urea dengan aluminium clorida ...apa Alcl dengan EMlmCl mr anda mmbuat saya bingung...
chould you tell me the Elml elektrolit..mr.??
Thank you so much for this amazing video!
Are purity level of this alcl3 is 98% ?,
more importantly it must be anhydrous
@@chemicum i am mixing anhydrous alcl3 98% and urea 99% in common air, the result is the viscosity is too high not like yours, and after a month in glass bottle, it become white hard powder, may be it truly need inert atmoshphere for making DES.
@@teknosql4740 Absolutely, the ionic liquid solidifies the moment it gets in contact with air moisture.
i spent 5 hours looking for this.
Why, I found this channel that late... I could won all competitions in my schools using this technology...
battery competitions?
@@chemicum Tech competitions
very elegant research system
Really awesome video guys, thanks for sharing. At 2:50 min the lady talks about how you can make a super capacitor by mixing carbon with a binder. Could you please share what the binder is?
teflon
@@chemicum Awesome! Thank you so much! Is the Teflon porous under those circumstances? I thought it was beneficial if the electrolyte could penetrate the carbon substrate? I have tried making a Zinc chloride and urea electrolyte but have not had much success. It only conducts when heated! Is there a good one most people could use with "common" ingredients?
@@zaneaussie Indeed, we tried urea-AlCl3 ionic liquid from low purity precursors and the result was solid. From higher purity precursors, it was almost liquid at room temperature.
@@chemicum Ha-ha yes I had the same issue. It keeps crystalizing when it cools! I thought perhaps it was because it wasn't homogenized properly so heated it more and for longer but the result was still bad lol . I wish there was a way and I keep looking for something we can make without expensive glove box and using commonly found chemicals. If you find something please share :-)
@@zaneaussie I noted that wikipedia lists that AlCl3 decomposes into the anhydrous form at 100 C, and wikipedia also lists that Urea only starts breaking down above 133 C, so maybe setting a hot plate to hold precisely at 105 C will allow you to drive off the moisture non-destructively? Not too certain though since some literature on Urea+AlCl3 seems to suggest Urea can produce decomposition products even if not reaching 130 C.
So cool
ALCL3 IS HAZARDOUS TOXIC GAS RELEASED WHEN REACT WITH MOISTURE. PREPARED IN INERT GAS CHAMBER. BUT I WANT TO ASK YOU , ONCE THE IONIC LIQUID IS MADE IF THE BATTERY BREAKS WILL THE IONIC LIQUID REACT WITH MOISTURE?
yeah, it reacts with moisture
@@chemicum thank you , your tutorial was very informative. Is is possible to form a H2O2 , KOH Urea ionic liquid -
@@samosdolphins123 don't know, peroxides are explosives usually
Nice explination
Please, the carbon electrode at 1:10 min from which kind of carbon is done?
Thanks
Can you help me in making alcl3 and urea electrolyte. Thanks in advance for this valuable information.
hi what is the teflon solution used for supercap , thx for your share
Hi, i tried to make alcl3+urea ionic liquid but it back to room temperature it solidified
did you use an argon atmosphere or nitrogen?
I made two batches of urea-AlCl3 ionic liquid. First, I used cheap fertilizer grade urea, not pure and result indeed solidified at room temperature. In the second batch I used higher purity urea and dried glassware with higher care - and the resulting ionic liquid was actually liquid at room temperature. So, perhaps the key is to purify urea.
@@Meleeman011 I use some unhydrate cacl2 to remove water vapor from box. I don't use nitrogen or argon
@@chemicum I also use cheap feritilzer urea
@@chemistryguys3433 it should be purified
Does the artificial muscle with EmimBF4 have to work in a glove box?
Hello please what other electrode can be used apart from graphite?
This subject is studied heavily, but there is nothing better at the moment
I read that graphite reduces the life of the battery because it degrades over time
@@Aimmad19 Still, other electrode materials degrade much faster
Do you charge the battery before used to spin motor or directly use after giving electrolyte ?
Both ways work since it is rechargeable
what kind of binder is used for the activated carbon? Does it make a more efficient cell if that process is also done in an inert gas chamber to keep o2 out of it as well?
binder is teflon in water so adding it in glove box is not a good idea. However, later the electrode is dried and electrolyte is added in argon atmosphere.
what are good solvents for dilution of these ionic liquids? with what effect on conductivity?
what about bromide instead of chloride?
There are several possible solvents, for example nitriles (acetonitrile) or organic carbonates - solvents must be hydrophilic, no OH groups and must withstand high voltage window. Bromide maybe - I think there should be some research available.
@@chemicum @chemicum dam,"hydrophilic solvents" I was hoping for some hydrophobic solvent as most of these eucltic ionic mixtures are very sensitive to water if not downright delquiescent..
. I want to try these ionic liquids in a pyridine/DMSO/isononl myristate/PDMS jelly
and a lot of other fantasies till I get some funding...
still planning to experiment as much as possible regardless, even if it comes off more like alchemy.
do you have any thoughts on using bismuth as the metal ion instead of aluminum?
@@petevenuti7355 bismuth is quite heavy and the energy density will remain low.
@@petevenuti7355 Yep, there is lots of research that can be done regarding this, it is still quite new topic
@@chemicum energy density per pound yes, but of course there's by volume for stationery applications. Bismuth is also a multi valance element that potentially allows exchange of multiple electrons per reaction. Might be scenarios when it's advantageous.
I am glad to watch your iconic lequid effect, pls make video on on iconic lequid by which melanin from hair can be extracted .
what is the type of binder materials that you are using?
teflon
The ionic liquids AlCl3-Urea need rising in temperature but how i can keep it liquid ?
And using it as electrolyte?
@@mohamedallam6371 it is half-solid at room temperature, but should be liquid at 60 oC.
Quick typo report: due to the unique way in which the English language is formed, 'inflammable' means 'flammable'. I think you want to say that the ionic liquid is 'uninflammable'!
Or "non-flammable" or "non-combustible".
damn, thanks for noting
AlCl3 and urea is an ionic liquid with relatively low conductivity of 1 mS per cm. Does adding sodium tetrachloroaluminate (NaAlCl4) improve its conductivity? Will this combined ionic liquid solution work for Aluminium ion battery as electrolyte?
Also, will activated carbon cathode work for aluminium ion battery or do we need pure single layer graphene?
I saw a paper, where many suitable additions were tested. Indeed the AlCl3-urea is a bit too solid for room temperature and should be heated up a little for a better performance.
@@chemicum Thank you very much.
Hai, what is the current and volts of urea +alcl3 base battery
max voltage was about 2 volts, current somewhere within 0.15 and 0.5 A. Did not actually measure discharging current but charging current was up to 0.7 A.
I will measure the cell in a few days.
forgot, the battery made in the video was with EMImCl4. I guess urea-AlCl3 gives less power at room temperature since it is more viscous.
@@chemicum sir where we get EMlmcl4
@@chemicum maybe in my place viscous Will decrease in hot climate the average temperature in my place is 35c
35 oC is much better for urea-AlCl3 ionic liquid
Very nice. Is this ionic liquid can also be used to dissolve cellulose.
true, as the video was already long, I left out other applications for ionic liquids
0:43 Wait isnt EMIm cation imidazolium salt, not alkyl ammonium salt?? excelent video though
it is indeed imidazolium, which is can be called more generally as ammonium derivative
What purity level of your alcl3 and urea ? Where do you mix both, in common air room or in inert gas ?
high purity is better and definitely in inert atmosphere
Great video thanks to you all. Could I just ask what substances might be used as the "binder" to mix with the activated charcoal in a supercapacitor. I would really like to try making that!
For example teflon solution
Why Al emimcl battery not manufactured for public consumption?
it is quite new design, it may be commercially available soon.
Is there a cheap way of producing emimcl in a lab setting?
@@Aimmad19 no, but the carbamide ionic liquid could be made at home
@@chemicum okay can I use it as the electrolyte for the aluminum battery?
@@Aimmad19 yeah, but power is not very high
Is an Aluminum Chlorine fuel cell possible using fairly conductive ionic liquid? What ionic liquids may be possible candidates?
HELLO. COULD YOU TELL ME WHAT IS BINDING IN YOUR SUPERCAPACITOR.
teflon
Are you have plan to make commercial battery ?
Can you please share some more details over artificial muscle ..
What exactly? It is like supercapacitor, but made of special materials. It bends when voltage is applied
Amazing video! Just one question, would ot be possible to make AlCl3-EmimCl ionic liquid outside a closed off environment as you used?
In a plastic bag, which contains something that removes air moisture
@@chemicum And that is to prevent AlCl3 from reacting with moisture? Or does the EMImAlCl4 ionic liquid also react with moisture? Or is it EMImCl that reacts with moisture? Thank you in advance
@@pako8626 AlCl3 reacts with water and moisture and so does EMImAlCl4. EMImCl absorbs some water from air, but does not react with it.
@@chemicum what happens when EMImAlCl4 reacts with moisture? And thank you for your time to respond to my questions! Its very helpful!
@@pako8626 I guess that AlCl3 will turn to hydrated AlCl3 x 6H2O, which causes solidification of the liquid.
chould you explain detail about Elmlbf4 mr...
1:34 did you just bust or something?
?
You shown too fast I could not catch up with EMIMac ... I want to experiment this ... How I can make Emimac
You mean EMImOtf or EMImAlCl4
@@chemicum EMImAICL4
I want to ask if a substance can exist in its ionic state?
Like can in charged state
Like Fe in Fe+
If yes then how long can it exist?
What are radicals? (Chemistry)
Yes these questions are haunting me so much for so long plz answer or direct towards an answer.
there must be of course something that stabilizes that charge
Why don't this meterial use for humanoid robotic blood??
It is kind of more like a solvent - it does not carry energy and oxidizer - like blood has glycose and oxygen in red cells. But of course fuel can be added, for example ethanol to be used in a fuel cell.
So if aluminum battery with this ionic liquid is promising, why hasn't it become popular on the market ?? Aluminum is much cheaper, more abundant, recyclable, and this battery is not prone to exploding like lithium. Also, 2 volts for a rechargeable battery is really good as far as batteries are concerned. Performance may not be up to par with lithium, but the advantages can make up for it.
It is quite new technology, it needs some time before entering market. There are many scientific papers coming out concerining this topic, perhaps some improvements too.
Graphene Manufacturing Group Ltd (Stock ticker TSXV:GMG) is building a factory for Aluminium Ion batteries based on Urea-AlCl3 ionic liquid with graphene and aluminium foil electrodes. The graphene has micropores blasted into it to hold Al3+ ions.
4:30 - русский акцент?
ну так... в титрах так и написано - Евгений Сорокин
i searched heptachlorodialuminate into duckduckgo and google, and they returned nothing.
Rather search aluminum chloride and EMImCl
atlast ionic liquid is an evolving head of a housefly😂😂😂😂😂😂😂
Chemicum without the chemi 😳
no, no video without chemi
Что тут происходит 😱😱😱😱
Евгений Сорокин из видео должен все по-человечески рассказать...
