Very nice and thank you for telling the secret about handling surface tension.
No problem brother.
I'm so excited to see this!
Great video. My question is: have both sides of the collector plates been painted? Thanks and continue the great work.
Very well done ! 🎉🎉🎉🎉❤❤❤ Finally somebody who made a real good selfmade Supercap... Great idea to use thicker Alufoil and also use this pos device paper as separator...🎉🎉 Well done, great ideas ! Can I use your Video part to translate it with my voice into German language for my overunitydotde KZhead channel ? Many thanks my friend. Best regards from Stefan from Berlin Germany and a happy new year.🎉❤❤❤
Thanks a lot for your nice and sincere comment. Of course you can use my video but please mention about my channel and explain where you get the video.
Wow! You are always superb! MashaaAllah
Thanks brother 🙏
Excellent Job my friend...hand up...!!!Nice...!!!
Thanks
A more quantitative evaluation would have been nice - put a load on it and drain it and show us a graph of the current and voltage vs. time, or something like that. Also, does it degrade with use? How many times can you cycle it and still have it work well? Etc.
great video
Thanks 🙏
Very nice

hi, great video, I am planning creating a few for my self, however I have few questions in regards to capacitors in general , 1. is it better if I have a 1.2volts 500F capacitor than a 12volts 500 micro farad capacitor, what the differences will be in each of them regarding charging and discharging time, current differences, etc
It’s better to use 1.2 volt 500 F Supercapacitor
To get 12v one have to make 10-,11 of them? Will be charged and it rechargeable? Kidos
As a Fine Print Note for anyone pondering putting these in a Series or Parallel arrangement to increase the working voltages or currents, be sure to get the dimensions of your sheets as close to the same size as possible, the thickness of the paint goop as consistent as possible, and all measurements of everything accurately measured and consistently mixed. I think you get the idea: We aren't doing a Stir Fry, so we just can't toss in so much of whatever. When we're banking these things, we're baking a cake. Measure that stuff to the 1/10th of a gram.
Thanks for the wise and fenomenal suggestion
Great point measure or weight the solution for each plate of the capacitor will make the most difference. As well as weighing the capacitor plates and removing material to make them as close to the same as possible
@@RustyShakleford1 Well, with the plates, it's the surface area that's critical. We just weigh everything else out so it's "The same" on each plate/in each cell.
Gerçekten senin yaptıkların diğerlerine fark atıyor. Ciddi anlamda tebrik ediyorum kardeşim 👏👏 Bu arada kendi kendine boşalma testi yaptın mı? 1.35 voltu ne kadar süre üzerinde tutabiliyor veya 24 saat sonra yüzde kaç düşme oluyor?
Sağol kardeşim benim. O testi yaptım. Bir saat sonra 1,25 e düşüyor bir gün sonra 1,20 ye bir hafta sonra 1,15 e düşüyor. Sonrasında düşme oranı çok yavaşlıyor. Anlayacağın fabrikasyon üretimi olanların değerlerine çok yakın.
hocam bu işlemi birde bakır ve aluminyum'u bir arada kullanarak yapabilir misin? kendi kendine dolması ne kadar sürecektir acaba. birde yapılan kapasitörün kullanım ömrünün uzatılması için gerekli detaylar ve trick'ler de olabilir. hangi materyalleri kılıf olarak kullanabiliriz, en uzun ömürlü izolasyon nasıl olabilir gibi.
Süperkapasitörlerde anot ve katot olarak farklı metaller kullanmak iyi sonuç vermez. Bir bakalım kardeşim diğer dediklerine. Çünkü izolasyon ve aşırı şarj etmeme önemli konular.
I really enjoyed watching your video and I hope you produce more similar videos in the future. I have a question about the sodium sulfate, if you soak the paper in a conductive material it shouldn't cause a short circuit?
Thanks brother. When it comes to your question; as electrolytes are ionic, they don’t cause short circuit.
May I know the name of the electronic material used in the capacitor and how can I get it?
Una pregunta el electrolito puede ser etilenglicol me gustaría saberlo gracias un cordial saludo desde España
At that time you need to use different salt instead of sodium hydroxide

I read a research paper from an Indian university on separator material which stated that fibre glass was the best separator. Your thoughts on that and would it work with your Supercapacitor?
Very good video! I just have a few questions: If I am using sodium sillacate as the binder, and and I want to use Sulphuric Acid as the electrolyte, what should the concentration of the Sulfuric Acid be? Thanks!
Sodium silicate and sulphuric acid have a good compatibility. You can use 30% concentration. (Keep in mind that in this case you can’t use aluminum, you should use lead instead)
@@joyofelectronics9782 Sorry to ask so many questions, but what is that in molarity? Is it 30g H₂SO₄/100mL H₂O?

Hello, in one of your videos, you made both poles from aluminum and carbon and charged them as DC. How are the anode and cathode determined?
is the same at both poles. You should always use whichever you marked as positive and which as negative in the first place.
@@joyofelectronics9782ok thanks sir
great video, I have a few questions. does the liquid electrolyte evaporate overtime? does maxwell super caps also use a liquid electrolyte like yours? what is the best energy density (wh/kg) super cap you can hand make compared to what maxwell is already producing? what is the life and lifecycles of your hand made super cap?
Thanks. The electrolyte evaporate over time unless the case airtight. The electrolyte used in maxwell supercaps are the different, they are not water based but based on organic liquid compounds
Why not use mineral oil?@@joyofelectronics9782
If you add a 3rd layer of aluminum foil to the bottom of your stack before rolling it and use the top and bottom layers as terminals (ignoring the middle aluminum layer) , you can make a very nice 2.5 volt primary battery. Use a 1molar solution of potassium hydroxide as the electrolyte in this case.
Very interesting, please forgive my ignorance, but you said that you added graphite to increase conductivity, but surely isn't the layer between the plates supposed to be dielectric?
The Separator is dielectric material. Graphite increases the conductivity of active material on the plates.
@@joyofelectronics9782 thankyou appreciate your thorough explanation, I should have watched the rest of the video before commenting, all the best

How to make a 500F capacitor that operates at higher voltage(35v)? Do you have any suggestions?
There is no way to do this with current technology except connecting many of them in series
You'll never get near 35v super capacitor in one capacitor using an aqueous electrolyte, because of electrolisys. Your best hope is to serries many super capacitors and use an active balancer to ensure none of the capacitors gets over charged. On the other hand, You can make a 35v electrolytic capacitor by electolytically oxidizing the anode electrode. You'd use two aluminum plates, and two paper separators (no graphite or activated carbon theybare useless in an electrolytic capacitor), and role your capacitors then put it in an electrolyte bath to soak. Then you'd form the insulating layer by passing an electric current through your capacitor. Use a bench lab power supply that can supply sufficent voltage and limits the current to maybe 50 to 100 miliamps. The aluminum anode will begine to oxidize on its surface forming a thin layer of aluminum oxide acting as a dielectric insulator. If you plan on feeding a rectified sine wave to your capacitor, you should form the capacitor to a value reasonably above the peek. 35v rms × sqrt(2) is just under 50v peek . You might want to form your capacitor to 55v or 60v for the added safety insurance and avoid the risk of exploding your capacitor with high currents when exposed to voltages above that which you formed your capacitor to tolerate. Lastly, the higher voltage you form your electrolytic capacitor to, the thicker the dielectric oxide layer gets, and that inevitably lowers the capacitance.

What liquid does the carbon mixture use?
Distilled or deionized water
Can I use salt water, and questions is why electrolyte is not making short circuit in capacitor
No you can’t use salt water. It will deplete the Al foil.
how do you increase the voltage ratings?
Sadly you can't with aqueous electrolytes, because of electrolisys.
Where can I get the active carbon, graphite and deionized water please
You buy on internet brother.
Why not coat both sides of the electrodes?
What if I want the super capacitor to be 1000uf x 2.5,/2.6,,-7 votes or 500 uf x ,2.5v should I increase the length of the foil?
You'll never get near 2.5v Using an aqueous electrolyte, because of electrolisys.

Isn't the paper in the POS machine coated with chemicals to create writing with heat? Shouldn't the paper be inert?
Yes but that paper inert enough
Can sodium hydroxide be used instead of sodium sulfate?
No
Plz can you make supercapacitir more powerful then this with same aluminum foil❤
I am working on that.
gel battery electrolyte preparation
What if you use a solution of sodium sulphate instead of deionized water when blending the graphite powder, activated charcoal, and glue binder. My therory is that as it dries it will form sodium sulphate crystals in the graphite, activated carbon, and glue binder matrix. When you add water after rolling the capacitor, the crystals disolve away leaving tiny voids with a high surface area much like activated carbon provides. What might not work as expected is if salt crystals form on the surface rather than throughout the carbon film.
It’s not good
Cool demo. Question: Why not just put NaSO4 in with the carbon? You could also pre-soak and dry the paper. Seems like these would guarantee a good distribution of ions from the moment it got wet.

how many gram of sodium sulfate and deionized water you used in this video
He said one mole of sodium sulphate. But there are two or three problems with this. First is what is the hydration of the starting crystals, and secondly, we don't know how much water. Hydrated Crystals of sodium sulphate and their molar weight. decahydrate (Na₂SO₄ · 10H₂O) 322.192 g/mol heptahydrate (Na₂SO₄ · 7H₂O) 268.128 g/mol monohydrate (Na₂SO₄ · H₂O) 160.047 g/mol anhydrous (Na₂SO₄) 142.04 g/mol. ____ Did he mean 1 mole to 100 ml or 1 mole to 1000 ml. Sodium sulphate decahydrate is the most soulable and would not completly disolve in 100 ml of water at room temp but 1000ml will. So it might be safe to assume he meant 1 liter of solute. But we still don't know 1 mole of which hydrate of sodium sulphate. Sodium sulfate decahydrate (Na₂SO₄ · 10H₂O): This is the most common form of sodium sulfate commercially available, also known as Glauber's salt. It is typically sold in powder or crystalline form and is used in various applications like detergents, textiles, and glass production. Sodium sulfate heptahydrate (Na₂SO₄ · 7H₂O): This form is less common than the decahydrate but is still occasionally available. It is usually encountered as a technical grade product and may be used in specific industrial applications. Anhydrous form: Sodium sulfate anhydrous (Na₂SO₄): This form is also available, but it is generally less common than the decahydrate. It is often referred to as desiccated sodium sulfate or salt cake. Due to its hygroscopic nature (tendency to absorb moisture), it is usually sold in sealed containers to prevent caking. It finds applications in various industrial processes like the production of paper, textiles, and chemicals. And to the third (potential) problem, I suspect he purchased Sodium sulfate heptahydrate Or possibly Sodium sulfate heptahydrate. But I don't know if he was aware of the hydration and considered it when weighing out the ammount to add to the liter of water. Reguardless, if you measure out 142 grams of decahydrate or 322 grams you should still be able to disolve both completly in 1 liter of water and they should perform rather similarly although 322g of sodium sulphate decahydrate is probably more conductive than 142g of sodium sulphate decahydrate.

Thanks brother. I have been searching to find and discover new things or practical ways to do things and share with you.
Nice! Can you do li ion battery next 😂😂😂

Sure
So you charged it with 2.1V 1A for 10 minutes.
No the voltage determines by the charger when you charge with 1 amp
I drink a lot of beer. I will scissor up some aluminium tins into spirals and try it out. Are you sure it is a capacitor and the carbon does not react with the aluminium? Does putting capacitors in series increase stored amps or volts?
@@kurbads74 you can try it with peace of mind. If you do everything correct the result will be amazing. As a surfactant use methanol. Putting Supercapacitors in parallel increases capacity but same voltage. Putting them in series increases voltage but lessens capacity.

Graphite powder
Excuse me, I am an Arab person and I understand the English language with difficulty, so I translated some of your videos. I want to make a battery at home. I have tin, I have graphite and activated carbon, but I cannot prepare sodium sulfur. Is there another alternative to sodium sulfur? I ask you to respond quickly, because the electricity was cut off in my country. Very much, and I want to make a strong battery to operate the inverter device. The children here get tired because of the extreme heat. I hope for a quick response, thank you. Or I want to communicate with you so that I can make it. Thank you very much.
You can use sodium sulfate in the case of you use aluminum foil, but if you use copper foil you should use sodium hydroxide 👍
@@joyofelectronics9782I do not have sodium sulfate. Is there an alternative other than that? I use aluminum foil as I mentioned to you, and I do not know what the element sodium sulfate is. I ask you to replace this element because I do not know it. Thank you very much.

Deionized or distilled water
I created one using some 8 inch long 1 inch wide strips of kitchen aluminum foil. 4 layers of toilet paper tissue as the separator. and a thin painted layer of ground pencil graphite painted on With the electrolyte of sodium sulfate. However it would charge up to about 1.5 to 2 volts. it had very poor performance and poor conductivity. The best it could do was light up an LED for a minute or so. very dimly. or spin a small DC motor for a second or two. Only a small improvement over a regular electrolytic plain aluminum foil capacitor. I think my pencil graphite was bad because it had high resistance. A short only couple cm piece had a resistance over 1 ohm. The bond of graphite to the aluminum foil was excellent. even after disassembling the graphite remained on the surface of the foil current collectors without flaking off or delaminating. it did not stick to the paper. so my bond was good. but the resistance was terrible. Probing two spots close to each other on the kitchen foil showed resistances in the kilo-ohms range I cannot find conductive graphite powder available to purchase online. Could I get some from some high quality pure graphite rods instead possibly? That can be ground to conductive graphite powder.
Only graphite powder doesn’t work. You must use activated charcoal
@@joyofelectronics9782 I tried both. and using both together. Something is still wrong. I get kilo-ohm reading between current collector and anywhere on the surface of the active material coated on the aluminum surface. I tried without graphite and only using activated charcoal by itself and got better result. Something is wrong with my graphite? Why the graphite makes it not conductive? if I only use activated charcoal active material by itself it works better. but still doesn't have a lot of capacity.
@@realflow100 you really have some different problems. I guess you put binder over recommended scale or the conductivity of your graphite powder is too bad
@@joyofelectronics9782 I tried with nickel strips and it worked AMAZINGLY. I got 0.57 farads out of a surface area of 0.4 inch by 1.25 inch flat nickel strips and active material as a thin layer applied to the surface. Not sure whats wrong with the aluminum foil but the aluminum foil just doesn't work when I try it. However nickel works fantastic. I got a short circuit current of this cell at about half an amp of current. it can charge up to about 1 to 1.2 volts maximum and is symmetrical and can be charged backwards too!. I used 50/50 graphite activated charcoal mixture. 2.5 grams of activated charcoal 2.5 grams of graphite. Added 40g of water and mixed with a motorized mixer for a few minutes until smooth and fluid. Then added 1 gram of PVA polyvinyl acetate adhesive and mixed it again for several more minutes. It became thicker and more viscous and required about 5 to 10 minutes of mixing to become a good smooth fluid consistency. Then I applied it with a small syringe for application method for the nickel strip current collectors. I used sodium sulfate electrolyte as a saturated solution. You could use 75% saturated instead if you are worried about solid crystal precipitate forming at room temperature. It works finally!!! I just need larger sheet rolls of thin nickel foil to use. Also would help if the nickel foil was annealed and not super springy. it is difficult to work with springy metals. as they dont like to lay flat and stay in the shape you want them to stay in. if I were to scale this design up 100 times more surface area I would have 57 farads and approximately 50 amps of current output if short circuited. it would need a substantially more beefy design and construction overall to handle such currents. No problems with electrolyte soaking in to my active material either. I used a thin very porous separator. similar to coffee filter paper which allows rapidly soaking of the pores and of the active material.
@@joyofelectronics9782 I'm not sure what happened but I think my last reply got deleted or didn't send properly. I got it working using nickel foil instead of aluminum foil. Nickel stays conductive and doesn't form an insulating oxide layer like aluminum foil. I scuffed up the surface with a wire brush and painted on my new iteration of active material which is a 50/50 mix of graphite powder and activated charcoal. 5g active material 1g of pva glue binder 40g of water. for both electrodes. I got 0.57 farads and 0.5 amps short circuit current from a tiny strip only 0.4 inch by 1.25 inch across single side coated strips of nickel foil from battery terminal spot welding strips. It works! It finally works! I guess my active material recipe doesn't want to form an electrical connection to aluminum heavy duty kitchen foil. I tried so many times and never got any current to flow that way. But using nickel strips it worked beautifully! I was able to power a small DC motor for a few seconds! It could charge at 100mA charging rate current over and over very low internal resistance. high performance. just very small. Looks like I will have to look for some larger nickel strips if I want to make a larger rolled up supercapacitor version! Also I noticed my active material only has a very small bend radius. Cannot bend more than a few degrees without cracking and separating from the surface. its very brittle and crumbly. Not very flexible. So I would need to make a really wide roll around a plastic bottle or something for support to prevent the active material from cracking and separating from the current collectors Or instead I could make some flat rectangular sheets with tabs and stack them in parallel to make a pouch style rectangular cell. That might be easier to handle. Also it seems lead sheets can be used as well. They also seem to work very well with the sodium sulfate electrolyte and activated carbon and graphite material.

It’s hard to understand you could you talk a bit faster?
hmmm this is not a capacitor its a aluminium air battery ... nominal voltage 1.2V to 1.6V , as soon as the alluminium electrodes are consumed then you cant recharge it because you would have to melt the aluminium oxide again.
If you use polyurethane and add aluminium to one mixture and graphite to the other you can make rubber conductors that don't corroded as easily... And they're polarised, for an electrolyte sodium chloride is fine add a pinch of aluminium oxide and a punch of ultra fine graphite powder to the electrolyte mixture and away you go... Long lasting battery cell that fast charges, combine a few in series and parallel to amp up the current and voltage potential and away you go... Polyurethane can also produce some very low resistance values with graphite... Virtually room temperature superconductor values which makes for very fast charging compared to normal metal conductors... Your quite right also... It is a battery not a capacitor, seems the new generations don't know what a chemical battery is... Or the difference.
i need to know, because this cannot be real, how the hell can you get 500F (FARADS) from a half meter tin foil, i mean, a real 500F 2.7v cap is packed so tight and the foil is super long. I guess if this is real, the caps should come down in price very soon. Very nicely done video though, but next time you need to open the capacitor without cutting the video after testing, to show there isn't any battery cell in the container =)
There are some other videos that l shows inside the capacitor brother
😂🤣😂🤣😂🤣😂🤣
I see low self discharge rate and much power comparing a fish tank Activsted carbon and graphite powder... Are you sure that you added only AC and graphite powder not carbon nanotubes becusse the color of graphite powder is so dark 🧐

@@ignilc you must learn to use google to find information you need, capacitor does not have plateau voltage, and capacity is far below battery, but it can store and release electric in high speed, so its not suitable to replace battery position, its suitable to stabilize voltage
