I think you can improve the quality of your supercapacitor if you replace the ordinary paper with the special one. That is because the ordinary paper is not chemically neutral, it has bleaches and other stuff, so it is somewhat conductive and decomposes easily. By using the right paper you would reduce self-discharge and prolong the life of your device. Great project, by the way!
Yep, this is why in old tube electronics you have to change out all the paper based capacitors because the paper degrades over time ruining it's insulating properties.
Thank you for this.... I watched many DIY battery/ supercapacitor videos, but it annoys me that they never tell us the small details. When I try to replicate them, it always fails. The deionized water and the sonication were very helpful tips.
Before caping the sup cap add some extra electrolyte and put it in the vacuum chamber for few minutes. Under low vac so it will not foam over and slowly lower The vac pressure until the foaming stops, always top up the electrolyte. Sup cap can be used sooner, no need to wait 1 day after the vac treatment.

@@kerloesmedhet3480in case you use aluminum foil you have to use different electrolyte because sodium hydroxide immediately destroy aluminum foil. When you change electrolyte depending to this you have to change binder so and so. So it is the simplest way to use copper foil bro.

Nicely done, but consider degassing with a vacuum. Also, consistency might be improved by using doctor blade and a rolling mill for calendering the electrodes.
That is NOT a "supercapacitor", that is an electrolytic cell, furthermore once applied the electric current it produce hydrogen gas and the copper foil oxidize. To make a real supercapacitor you need a NOT aqueous polar liquid, like for example pure acetonitrile, and seal very well the plastic tube.
You are mistaken my friend there are both aqueous and non aqueous type of Supercapacitor. If you apply max 1.4 volt to charge this Supercapacitor there won’t be any electrolysis so hydrogen gas won’t produced.
I think this is meant to be a electrical doublelayer cap EDLC after Zhang, Candeleria et al 2013. Which is more a psuedocapacitor than supercaoacitor. ion dffusion galvanic than is electrostatic. Ok so people will be making their own replacement EV batteries instead of paying out $30,000
All that is needed to make a supercap is 2 foils made of an unrective metal, activated charcoal, graphite powder, distilled water and a mesh spacer to ensure the charcoal layer is uniform. Both the graphite and activated charcoal must be free of ions as possible. ❤
Thank you very much for the video! Very informative! I would like to clarify.

Before mixing all the components, you processed the mixture of graphite powder and activated carbon in water in an ultrasonic bath. Then all the components were mixed together and applied to the surface of the previously cleaned copper foil. Did I understand correctly? Why did you choose this ratio of components? Have you experimented with other proportions?
You did understand very well. Yes bro l experimented and search for years. This is the best ratio. Make sure that you mixed the mixture very well. Thanks for your comment bro.

A capacitor will have seperators known as dielectrics. There would typically not be electrolytes (conductive solution) saturating the dielectric. This device may be more of a battery than a caoacitor. I am going by memory so I maybe missed something in the video. 200 fd, or even 100 fd are a tremendous amount of capacitance, is it not? I have personally used a 1 fd cap, some 20 years ago. About the diameter of a quarter and 3/4" high. That became possible only thru new technologies in the process of creating surface area thru porosity. Again, dont take my comments for gospel.
supercapacitors use more than just normal capacitance; specifically they use double layer capacitance, pseudocapacitance, or both if i understand what I've been reading and listening to correctly. I don't remember what double layer capacitance is but iirc pseudocapacitance is when ions from the electrolyte are attracted to the charged plate of a supercapacitor and help give additional capacitance beyond what a true capacitor would have.
You are freaking awesome. I hope you can share some information like, what aspect of the methods or materials determines the voltage and the capacitance of the super capacitor?

Here's a good one to try.... Using polyurethane make 2 different mixtures one containing graphite and one conductive aluminium powder(the finer the better). Then with the mixtures make 2 conductive strips one from the graphite one from the aluminium and when they are dry tape a wire to each one... Then add the separator and electrolyte(do not over saturated) and roll it up the same... The rubber conductors are already polarised so it should give off a pre charged current with uptona 1.2v potential and a considerable amount of amps... The idea of this is to make less or virtually non corrosive conductors which means stronger electrolytes can be used... Iv found ash especially cigarette ash to be a great electrolyte with less corrosion rate than sodium chloride, blood too is unbelievable stuff and you might be surprised to hear that tests with semen have proved to be quite shocking... Blood will still corrode but at a very very slow rate, while other bodily fluids don't seem to cause any corrosion,
When your making this capacitor How will you know what the voltage will be,How will you know if it's 400 -600 volts, or 200 volts. That's what i need to know
The electrolyte that you used determine the operating voltage. The operating voltage of all of the aqueous based electrolyte is 1.2 volts. When it comes to capacity. We calculate according the duration of the time.
Hocam merhabalar, benim bir sorum olacaktı. Burda bakır folyo yerine alüminyum folyo kullanmak istiyorum, o yüzden sistemde ne gibi değişiklikler yapmam gerek detaylıca anlatırsanız çok iyi olur hocam. Şimdiden çok teşekkür ederim

Thank you so much my friend. Unfortunately here is the only way you can contact with me. But l will try to help you in any way l can. So you can ask everything you want brother.
Thank you for your very interesting video. There is one point i don't understand and i hope you can explain. When the cap is finished and filled with electrolyte, why doesn't any charge built up in the copper foil just short out across the leads, which are emersed in the the electrolyte and, therefore are electrically connected. Thank you for helping to clarify.
Thank you. It’s about the working principle of the cap. As it is Double layer capacitor each electrode attracts the positive and negative ions of the electrolyte so they balance each other.
Can please tell me the ratio of the copper foil cleaner ( H2O2 + HCl ) And the compositon of the paint applied over the copper foil and the electrolite liquid
What kind of white glue for the active material do you recommend? Does ordinary Elmers glue work? Can I make the active material from ordinary or ground up activated fish tank filter carbon, distilled water, and ordinary white glue?
thank for efforts, only two questions what is the composition of the electrode material and the electrolyte and don't think that the same electrodes in the same electrolyte will lead to zero volt? ??
Can I use polyester cloth like the type used in athletic gear? It does not absorb water, nor decomposes. I have many tons available for free, and I have machines to mold capacitor cases.
capacitance of 2 metal plates 15cm by 10cm with dielectric material carbon with thickness 100μm(*1): approximately 7.5μF (microfarads). A metal sphere the size of the earth has about 1.4F. How the electrolyte can give 200F? !!! In usual electrolitic capacitors, they achieve high F values by allowing the distance to be very small, much less than 100μm. Why not a slow discharge test to show without a cut the discharge voltage and current of a know resistor? A typical brush painted thickness is about 50μm.
Nice work! btw you can get chemically pure NaOH from soap-making outlets. Drain opener is technical purity, often the pellets are coated with nitrate to minimize the hygroscopic nature. I don't know if this affects it much, but it's a thought. Did you weigh the NaOH and water? Or does any strength solution work?
Thanks brother. It doesn’t affect too much. I had either pure sodium hydroxide but l used drain opener as it can be found easily for people. But the one who wants make this Supercapacitor can use pure and higher quality sodium hydroxide.

Thank you for this video! Can't wait to build my own supercap My recommendation is to make shorter version of the video, people usually get tired of watching so long tutorials
There two basic way to find the capacitance. First one is discharge method and the second one is charging method. I used charging method. The formula l used: l/C = V (per second). So if you charge the 1.2 volts capacitor with 1 amp and let say it take 120 seconds. At that time we can say that the capacitance is 100 Farad👍
@@urvhalt All power is converted to heat. The question is whether you can do some useful work in the process, like spinning a motor, or forcing electrons against a gradient to a higher potential, i.e. charging. Heat doesn't make electrons leave the system, unless you're building a thermionic emitter like a CRT or something.

Hello, I am an engineering student, and I would like to know what type of glue and charcoal powder you use to paint copper. Each time we try, the paint peels off when it dries.
Great job guys. I learn a lot by watching this video and reading comments here. Please can anyone help me with how to charge my supercap using a potentiostat. Kindly help
My friend, I am trying to find the capacitance of my super capacitor but I can't get a power source, you mentioned that it can also be found by discharging it, for that I would need a resistor?
@@adrianretamozo4936this formula applies for electrolytic capacitors and super capacitors as well. It's general for capacitors which way of working is the same.
You can use a shunt resistor and an amp meter to measure the total charge stored by your capacitor. Or use a volt meter and ohm's law, but what you need to calculate is the current over time. Charge (coulombs) is the area under the curve, or the integral, of current. amps * seconds = coulombs. So measure amps every (dt) seconds until fully discharged, add those values together, and multiply by (dt). Smaller dt will give you more accurate results. Divide coulombs by volts at full charge, that's farads. P.S. It's easier the way he did it because he has a constant current charger. So all he had to do was multiply current * time / voltage

Your active material must stick to the copper foils well and purity of the materials actually the electrolyte is play an important role. Practice more times you will get better results.
Not as good as mix of them. Because graphite plays a critical role to increase conductivity. If you don’t add graphite the esr of the cap will be a significantly high.
If you’re going to use sodium hydroxide as the electrolyte you can’t use aluminum foil. But if you use sodium sulfate then you can use aluminum. But at this time you should use a special binder instead of white glue.
No problem brother. 10% graphite powder 90% activated carbon. Add white glue with same amount of graphite powder by weight. And necessary dionized water. Stir the mixture very well
Amazing video, could you please tell me the amount of deionized water and NaOH used in making electrolyte(like how much ml of water and how much gm of NaOH?)
It is a capacitor not a battery, the anode and cathode are identical. It is 'Super' due to huge surface area of activated carbon . What thickness copper foil are you using?

Blood will still corrode but at a very very slow rate, while other bodily fluids don't seem to cause any corrosion,
When your making this capacitor How will you know what the voltage will be,How will you know if it's 400 -600 volts, or 200 volts. That's what i need to know
The electrolyte that you used determine the operating voltage. The operating voltage of all of the aqueous based electrolyte is 1.2 volts. When it comes to capacity. We calculate according the duration of the time.
What is the thickness of the copper foil?
20 micron is fine
Hocam merhabalar, benim bir sorum olacaktı. Burda bakır folyo yerine alüminyum folyo kullanmak istiyorum, o yüzden sistemde ne gibi değişiklikler yapmam gerek detaylıca anlatırsanız çok iyi olur hocam. Şimdiden çok teşekkür ederim

I wish i discover ur channel sooner! Than u so much. Is there s a way to contact u.? Im doin research on biomass derived activated carbon supercapacitor.
Thank you so much my friend. Unfortunately here is the only way you can contact with me. But l will try to help you in any way l can. So you can ask everything you want brother.
Thank you for your very interesting video. There is one point i don't understand and i hope you can explain. When the cap is finished and filled with electrolyte, why doesn't any charge built up in the copper foil just short out across the leads, which are emersed in the the electrolyte and, therefore are electrically connected. Thank you for helping to clarify.
Thank you. It’s about the working principle of the cap. As it is Double layer capacitor each electrode attracts the positive and negative ions of the electrolyte so they balance each other.
@@joyofelectronics9782 I have started gathering materials to experiment with. You are an inspiration. Thank you 🙏
@@tomwoods6828 you’re very welcome mate.👍
Can please tell me the ratio of the copper foil cleaner ( H2O2 + HCl )
And the compositon of the paint applied over the copper foil and the electrolite liquid
70% hydrochloric acid 30% hydrogen peroxide. But the ratio is not very important. You can also dilute the solution with water.
Wow nice home ❤ work
What kind of white glue for the active material do you recommend? Does ordinary Elmers glue work? Can I make the active material from ordinary or ground up activated fish tank filter carbon, distilled water, and ordinary white glue?
Yes you can use those materials. But make sure that all the powders must be fine and materials should be pure as much as possible
Please reply me. I am looking for sodium sulfate in my country and there is no such ingredient. Are there some alternatives that I can find?
It depends, but if you use copper foil as current collector, then you can use sodium hydroxide, magnesium sulfate also.
thank for efforts, only two questions what is the composition of the electrode material and the electrolyte and don't think that the same electrodes in the same electrolyte will lead to zero volt? ??
Thanks brother. You can watch this video: th-cam.com/video/dq7tG_2dlg0/w-d-xo.htmlsi=q2rMtAU_Fr-Ls9S8
how did you connect or fix the copper electrode to the cloth?
Very very honest guy Allah save you and your family.
Thank you so much brother ❤️
Good wish is OK, but Allah can't save anyone, only Jesus can save my friend!
Have you tested how many charge-discharge cycles it can go through before it starts to breakdown? (Discounting any breakdown time of the paper.)
I am still using the supercap and it’s still working. (More than 1000 times charge and discharge for now)
@@joyofelectronics9782 very cool and quite inspiring. Thank you.

Can I use polyester cloth like the type used in athletic gear? It does not absorb water, nor decomposes. I have many tons available for free, and I have machines to mold capacitor cases.
capacitance of 2 metal plates 15cm by 10cm with dielectric material carbon with thickness 100μm(*1): approximately 7.5μF (microfarads). A metal sphere the size of the earth has about 1.4F. How the electrolyte can give 200F? !!! In usual electrolitic capacitors, they achieve high F values by allowing the distance to be very small, much less than 100μm.
Why not a slow discharge test to show without a cut the discharge voltage and current of a know resistor?
A typical brush painted thickness is about 50μm.
can i know what size the plastic tube for supercapacitor u use?. can i use glass tube and with different size?the height,diameter
Wow good job sir
Nice work! btw you can get chemically pure NaOH from soap-making outlets. Drain opener is technical purity, often the pellets are coated with nitrate to minimize the hygroscopic nature. I don't know if this affects it much, but it's a thought. Did you weigh the NaOH and water? Or does any strength solution work?
Thanks brother. It doesn’t affect too much. I had either pure sodium hydroxide but l used drain opener as it can be found easily for people. But the one who wants make this Supercapacitor can use pure and higher quality sodium hydroxide.
Merhabalar dediğiniz şekilde süperkondansatörü yaptım 1,2V ta şarj etmeme rağmen bir süre sonra 5-6 kullanımdan sonra akım düşmeleri gözledim. içine bakınca bakır elektrotlardan biri oksitlenmişti muhtemelen iki tane ayrı ayrı yapıp seri bağlarsak bu sorun çözülebilir.Yada elektroliti değiştirmek lazım galiba.
Selamlar kardeşim. Eğer aktif maddeyi güzel yapıp dökülmeyecek şekilde yaptıysan bu sorunun en muhtemel sebebi. Bakır elektrotlar sıvı buharlaşınca doğrudan sodyum hidroksite maruz kalmıştır. Yaptığını görmeden bir şey demek zor ama bu kadar çabuk deforme olamaz. Benim 5 yıldır kullandıklarım var. Çok çok az düşüş oluyor.
Thank you for this video! Can't wait to build my own supercap
My recommendation is to make shorter version of the video, people usually get tired of watching so long tutorials
I know that brother but l wanted to give and explain all the details and make it more sensible.
I know, right? People just have to rush off to the next tutorial they have to lap up instead of actually building anything.
Internal resistance?
Approximately 10 miliohm (0.01 ohm)
@@joyofelectronics9782 good thing you didnt short them leads... with 200F behind...
What type of glue did you use?
White glue (PVA)
My friend, what formula did you use to find the capacitance?
There two basic way to find the capacitance. First one is discharge method and the second one is charging method. I used charging method. The formula l used: l/C = V (per second). So if you charge the 1.2 volts capacitor with 1 amp and let say it take 120 seconds. At that time we can say that the capacitance is 100 Farad👍
@@joyofelectronics9782 Great! Thanks for the reply and your excellent work 😄
... the internal resistance converts some power to heat....
@@urvhalt All power is converted to heat. The question is whether you can do some useful work in the process, like spinning a motor, or forcing electrons against a gradient to a higher potential, i.e. charging. Heat doesn't make electrons leave the system, unless you're building a thermionic emitter like a CRT or something.
@@DFPercushThe charging process is not 100% efficient, thus some energy will be lost, leading to an incorrect capacity estimation.
Стеклоткань вместо бумаги и засунуть в термоусадочную трубку, предварительно обмазать клеейм. Потом залить электролит и спрятать в пластмассовую гильзу...

Would you please tell the concentration of HCl and H2O2 in the cleaning solution?
It doesn’t matter
🙏👊 great video, now ofcourse its all about surface area ,BUT, if given only one option , would you rather make your supercap in the wider (more turns) or longer (same diameter but longer length) to increase capacitence,,, are the effects even the same 🤔
Yes it doesn’t matter. It’s all about your choice. I like wider ones but it’s little bit difficult to roll😀
@@joyofelectronics9782 👊👍
why is it limited to only 1.4 or 1.2 volts??? is it possible to make 5volt ones?
Also, this is super cool stuff. right up my alley.
Due to electrolyte. Aqueous electrolytes are limited to the range between 1.2 and 1.4
Hello, I am an engineering student, and I would like to know what type of glue and charcoal powder you use to paint copper. Each time we try, the paint peels off when it dries.
Do you have an email address so that I can explain it better to you ? Thank you in advance!
You should add some more binder and mix it very well. Additionally clean the surface of the copper foil very well.
Sorry, English isn’t my first language, what do you mean by more binder ? 😅
And also, what kind of separator do you use ? Is PTFE good ?
Great job guys. I learn a lot by watching this video and reading comments here. Please can anyone help me with how to charge my supercap using a potentiostat. Kindly help
Thank u. What other electrolyte type can be used and easly availabe ?
Thanks. This is the most suitable one with white glue and copper foil brother.
Waiting eagerly for your next video
Thanks bro. I have been posted some more videos. I will be happy if you watch them as well🙏
My friend, I am trying to find the capacitance of my super capacitor but I can't get a power source, you mentioned that it can also be found by discharging it, for that I would need a resistor?
You need a resistor or a suitable power source or you can use a LED or a dc motor which you know it’s power.
@@joyofelectronics9782 Perfect, I was thinking of using the formula t/(R*ln(2)), is that correct?
@@adrianretamozo4936 l am not sure but l guess this formula is for electrolytic capacitors.
@@adrianretamozo4936this formula applies for electrolytic capacitors and super capacitors as well. It's general for capacitors which way of working is the same.
You can use a shunt resistor and an amp meter to measure the total charge stored by your capacitor. Or use a volt meter and ohm's law, but what you need to calculate is the current over time. Charge (coulombs) is the area under the curve, or the integral, of current. amps * seconds = coulombs. So measure amps every (dt) seconds until fully discharged, add those values together, and multiply by (dt). Smaller dt will give you more accurate results. Divide coulombs by volts at full charge, that's farads.
P.S. It's easier the way he did it because he has a constant current charger. So all he had to do was multiply current * time / voltage
This is interesting ❤
🤔 es un híbrido, batería inundada + capacitancia/densidad energética entre placas que podrías mejorar aplicando mayor cobertura de carbón activado...
El electrolito líquido me parece muy agresivo de forma natural con el Cobre, en un proceso de electrolisis (carga/recarga) se magnífica la corrosión...
Si bien no todos los capacitores (simétrico/asimétrico) requieren de electrolito líquido...🤔🕵️ en tu caso particular de batería híbrida quizás te convenga utilizar sulfato de Cobre como electrolito líquido 🤷
PDT: Para mejorar las prestaciones "sin agregado de electrolito líquido en Litio" debes reciclar la química de las baterías o pilas... Averigua cuál es el electrolito de origen para Zinc/Carbón, Alcalinas, NI-MH, NI CD, etc para reactivar nuevamente dentro de las posibilidades.
Aporta Manganeso, Carbón (♻️🔋)...
Recuerda que el objetivo de un súper capacitor es recargar ⏱️ 20 segundos para que nos suministre un mayor tiempo de aporte de energía.
Una pila común según el tipo de dispositivo (consumo Watts/Hs.), por ejemplo en una radio portátil dura 30 días aproximadamente. Sin mencionar celdas, pilas, batería con química ácido plomo, Litio, etc...
Voltaje + tasa de descarga se evalúa en Súper Capacitores.

Great idea, long battery life.
Please material, chemicals , how much qty mix, mentioned in description or your website link.
I have another question, if I left the battery for 1-2 days soaked in the electrolyte, can I charge the battery more than 1.2V? If yes, what is the maximum voltage at which I can charge the battery?
No, it won’t change. But if you add some iron oxide to the active material. The operation voltage will increase to 1.6 volts.
@@joyofelectronics9782 thank you. When I do something like this can I change the active material?
Can i use salt plus water instead of naoh?
No

Brother you can add some more water until it becomes in the form you want and you must add glue otherwise when the paste dry it will be just powder again. Do what l said you will be successful 👍
Thank you for advice 😊

(elimde ultrasonik temizleyici var ama senin bahsettiğin farklı bir cihaz ise çalışma frekansı ve varsa, uygulama ısıl aralığını bilirsem yapabilirim) alanım elektronik, kimya konusunda biraz kötü sayılırım :D bu yüzden belki sana saçma gelecek birkaç sorum olacak.
1- grafit karışıma eklediğin tahta tutkalının yüzey kaplamasını kolaylaştırmasını amaçladığını düşünüyorum. doğru mu?
2- sodyum hidroksit eklendiğinde, bakır üzerindeki grafit boyayı zamanla çözmeyecek mi?
3- kağıt materyal'in kullanılması kasıtlı mı? yani çözeltiyi emmesi gerekiyor mu?
Merhaba kardeşim. Tutkalın görevi malzemenin bakır folyoya yapışmasını sağlamak. Aksi halde kuruyunca dökülür. Kağıdın amacı kısa devreyi engellemek ama naylon filan olmaz çünkü elektrolit akışına izin verecek gözenekli bir şey olmalı. Sodyum hidroksitin grafik üzerinde çok fazla bir etkisi yok.
i made it the same way bt not working, discharging really fast , what to do
Your active material must stick to the copper foils well and purity of the materials actually the electrolyte is play an important role. Practice more times you will get better results.
@@joyofelectronics9782 could i have your email id
Hmmmm supercapacitor, supercapacitor... I have drinking game idea😂
Great video👍
Do you think it will give good results if I only use the activated carbon without using the graphite?
Not as good as mix of them. Because graphite plays a critical role to increase conductivity. If you don’t add graphite the esr of the cap will be a significantly high.
I suppose you can take graphite from electrode of AA/AAA zinc battery

If you’re going to use sodium hydroxide as the electrolyte you can’t use aluminum foil. But if you use sodium sulfate then you can use aluminum. But at this time you should use a special binder instead of white glue.

Friend can you share the materials you added to prepare carbon coat. I was unable to get the information clearly.👍
No problem brother. 10% graphite powder 90% activated carbon. Add white glue with same amount of graphite powder by weight. And necessary dionized water. Stir the mixture very well
