There are 2 types of carbon used in this preparation. 1 Carbon Black Nanometric powder, there are different types of carbon black, the cheapest are used as a pigment but have a conductivity not too high, the best is Acetylene Black which offers high conductivity but comes at a high cost. Of course, the use of the carbon black type, greatly affects the conductivity of the sheets that are prepared. 2 graphite micrometric powder, this powder is always conductive, if I prepare a pile of my graphite and at the ends at the distance of 2 - 3 cm I place the 2 tips of a tester I read a resistance of about 1000 ohms, if I then compress this powder or use glue to the Polyinylacetate as a binder the resistance is lowered again. So if a graphite does not have these values, it is not a good graphite, or rather it is polluted by other products. Another component that can lead to bad results is polyvinyl acetate glue, I use Henkel AG's Pattex, which has proven to be excellent for this use. Other brands can lead to worse results, in these glues in addition to polyvinyl acetate there are also other additives that can affect negative on the final product. At the beginning I had used a glue of Chinese origin but the results were bad, greater electrical resistance of the sheets and frequent cracks in the final product. So polyvinyl acetate glues must first be tested.

I wonder does it make any sense to spend a time on all of this (considering number of initial fails), if you can purchase 500F for €3? Can a home made supercap beat a manufactured one in terms of a capacitance, or a voltage, or a max current?
From an economic point of view it makes no sense, and a self-built capacitor is unlikely to outperform the commercial product. But here other factors come into play: it is the pleasure of experimenting, of trying solutions different from the traditional ones. And let's not forget that, even if in rare cases, experimentation can lead to unexpected and highly rewarding results
@@claudiohomelab8181 .. like an invention of rubber (they even tried to mix with soup). However since then, I cannot remember something interesting discovered outside of a lab (I mean a chemistry and materials).
Iron is a poor conductor of energy transfer and you will not succeed. It is very, very bad
If you dry it like a solar panel, can the voltage increase? Sir, I'm from Indonesia and I have subscribed your channel. Thank You
These graphite sheets generate a voltage when they are coupled by an electrolyte to an element of different electronegativity, there must always be an electrolyte. Thank you for subscribing
ok, I plan to try applying your composition in making solar panels in the hope of satisfactory results because I see that the working system is not much different from making batteries. If you have any suggestions on what materials are good or good for making solar panels. I thank you very much, healthy greetings always
Why do you use two sheets of nonwoven fabric that go between electrodes at 8:28? Can I just use 1? Is there a reason behind this? Also the middle electrode I presume the middle electrode would not contain any insulating glue, but the outer electrodes do have insulating glue that covers exposed metal, right?
Between the electrodes I use 2 sheets of non-woven fabric for the reason that with a single sheet I had noticed that in case of pressure there was a short circuit between the activated carbon particles of the 2 electrodes. The central electrode does not contain protective glue for the metal. While in the 2 external electrodes the metal is protected from direct contact with the electrolyte
Where do I get 50 micron aluminum foil? I cannot seem to find it anywhere. I see they sell up to 30 micron aluminum foil and also have really thick 500 micron sheets. Does thickness matter? I bought a 500 micron sheet but I am thinking that may not work well.
The aluminum foil I used was made from an old plate from an off-set printing press. You can safely use 30 micron or even 500 micron sheets, no problem.
Where do you buy sodium perchlorate? Is it supposed to be expensive?
Can be purchased at a laboratory chemical store, sodium perchlorate is expensive: 250g about 100€, and being classified in some countries as a precursor to explosives, may be subject to restriction in sale
@@claudiohomelab8181 I see the alternative is sodium nitrate, is this as good as sodium perchlorate? It appears to be cheaper too. If used the video mentions to use 91 grams in 100mL of water, is this the correct amount for the ideal electrolyte or is there a different ratio to be used? Thanks for your response.
Sodium nitrate is the second best alternative after perchlorate and is less expensive and easier to find. The voltage that can be reached is slightly lower. The solubility of sodium nitrate is 91 grams in 100 ml at a temperature of 25 ºC
@claudiohomelab8181 And is that how much I use per 100mL of water? Or do I use what I calculated for 5mol/L to be 42.5 g per 100mL for sodium nitrate? And the water used can be distilled or deionized water? I do appreciate your responses to the many questions I have asked by though way, so thank you.
@@Ryan-gf6bs To use sodium nitrate you need to dissolve 91g of NaNO3 in 100ml of water, the water can be either distilled or deionized

Hello, how to I get 10nm power from mesh 300 nickel 99.8. It would be highly appreciated if you give me some directions.
It is not possible to obtain carbon black in my country. What can I use instead?
You can not use it. However, remember that carbon black with its nanometric particles helps to lower the resistance of the electrodes. However, carbon black is also used as a pigment to make colors used in graphic arts, so you should find it in your country as well. Check it out here: www.jacksonsart.com/blog/2021/11/17/pigment-colour-index-black-pigments/

Glad that you know the best water based electrolyte for super capacitor is sodium perchlorate, but may aluminium perchlorate give higher capacity
Thank you for the clarification
I am a little curious why you didn't soak your layers of non-woven cloth in the electrolyte and then use your press to compress them down to a desired amount of saturation. I feel it would probably result in a more even spread of the liquid. Either way, this seems like a decent result from a home lab an a terrific way to turn a marginal supply of power into something useful.
I have to admit that soaking the non-woven fabric directly into the electrolyte is a better solution, in fact in the preparation of another supercapacitor I adopted this technique
@@claudiohomelab8181 I look forward to more of your videos in the future!

I suspect one might make a more active surface area by adding some the salt to the carbon slurry instead. When the water dries the salts crystalizes. The theory is that later when water is added, the crystals disolve and leave behind voids for ions to hide their charges in when the plates are charged.
It could be an idea to experiment with

Using nickel current collectors instead of aluminum. and a sodium sulfate or potassium carbonate electrolyte. and graphite and activated charcoal mixed 50/50 I was able to achieve a conductivity of 10 to 30 ohms directly measuring with the probe of multimeter anywhere across the surface of the active material on resistance scale setting I also tried a sample with pure graphite only and achieved 0.5 to 2 ohms. Nickel works much better than aluminum foil. more durable. more resistance to electrolyte and very high performance. I achieved over 500mA of current maximum charging current from a 0.57 farad test sample being able to charge and discharge instantly in less than one second. Very low internal resistance. and much more powerful. Size was only 0.4 inch by 1.25 inch and active material thickness only 0.3mm And a sheet of angel soft brand toilet paper tissue. Or a sheet of coffee filter paper (Coffee filter paper better durability more porous and consistent thickness) cut to size It works up to about 1 to 1.2 volts with very high performance. I used 10 to 20% polyvinyl acetate by weight to dry active material powder mix as the binder. no graphite sheet. no stainless steel mesh. nothing extra. Just be sure to roughen up the surface of the nickel sheets or foil before applying the active material layer to get it to stick better. Paint and spread a thin layer and let it dry overnight.
Thanks for sharing news about your trial, it's useful news! I use aluminum foil as a collector which then undergoes corrosion. In my last video I made a supercapacitor with protected aluminum that should solve the corrosion problem. For now, it works, but we will have to wait to see the final results. If it goes wrong I will use other metals, such as nickel foil, an alternative could be stainless steel foil
@@claudiohomelab8181 Yes stainless could also be used. Nickel might be slightly easier to work shape cut or handle. sand or roughen the surface etc. I recommend if your using flat sheets to highly roughen the surfaces thoroughly with sandpaper or similar roughening options before applying the active material coating. Makes it stick a lot better and you get a much better easier wetting of the active material and better bond. more conductivity. Sodium sulfate will give highest performance but too much will cause crystal precipitation to form. At room temperature probably 50% to 75% of the maximum solubility will be a good target. Too close to 100% will form precipitation and reduce performance. Nickel works extremely well much better than aluminum No oxide layer formation and high resistance to corrosion in neutral or strong alkaline electrolytes.
Hello Claudio, Would pouring the graphite foil directly on to the aluminium collector with the mould to limit its spread not eliminate one of the passages in making the electrode? Would there be any negative alterations to its performance? Thanks J
Hello Joseph, I can't print the graphite foil directly on the aluminum foil because the foil shrinks during drying and due to the stiffness of the aluminium would result in a completely cracked foil. Look here: ua-cam.com/video/CJnWq3MzMNo/v-deo.html at 07:29 As you can see the foil contracted but the thin plastic sheet followed its deformation and the foil is perfectly intact.
Yes, I should have thought6 of that myself. Thanks J@@claudiohomelab8181
Hello Claudio. Have you managed to improve on resistance? I'm doing some research work at a British University and the internal resistance that your graphite sheet contributes would drain a supercapacitor in no time. Your thoughts. Regards J Martin
Hi Martin, I am aware of this problem, to improve I should be able to lower the resistance by an order of magnitude, which on the one hand would be easier to do using acetylene black, but I would like to solve it using low cost materials. Now I'm using these electrodes in making a Water-in-salt supercapacitor with NaClO4 electrolyte, we'll see what happens Regards Claudio
genial! enfin une démonstration complète et détaillée, grace à vous je vais pouvoir avancer... vous êtes le premier à parler de la corrosion des electrodes et montrer une solution. jusque là j'utilisais des plaques d'impression offset recyclées de 0.3mm mais malgré l’électrolyte au pva/na2so4/kdp j'avais de la corrosion. personnellement pour le binder j'utilise pvp iodée "IO Shield" (produit agricole pour les trayons des vaches!!!) avec satisfaction. l'iode amène une action redox intéressante... un grand merci pour ce travail que vous partagez. PS: qu'utiliseriez-vous pour le stockage d’énergie hors réseau à moindre coût?
Bonjour Simonsimon, Merci pour votre appréciation, j’ai également utilisé de vieilles plaques d’impression offset en aluminium pour le collecteur de certaines électrodes, Je trouve très intéressante la nouvelle que vous m’avez donnée sur la façon de trouver du PVP (PVP iodé à usage agricole !!). Pour éliminer définitivement le problème de la corrosion, il suffirait d’utiliser de fines feuilles d’acier inoxydable comme collecteur des électrodes. Bien sûr, ceux-ci sont plus chers que ceux en aluminium, mais ils pourraient être la solution ultime à ce problème. Maintenant, avec ces électrodes, je construis un supercondensateur que je viens de fabriquer, je vais poster la vidéo. Pour le stockage d’énergie off-grid, mon idée est d’utiliser des supercondensateurs, Mais compte tenu de l’énorme capacité que le système nécessiterait et des coûts élevés actuels des supercondensateurs, cela n’est guère réalisable Cependant, s’il pouvait être produit à faible coût, alors ce serait la meilleure solution. Je te salue, Claudio

This looks really awesome. How about durability?
As for the durability of these graphite electrodes, there are no problems in contact with salt electrolytes, I have some cells with LiClO4 and LiCl electrolyte, and electrodes aluminum - graphite sheet still working after 2 years. They cannot be used with strong acids because they are slowly dissolved, with concentrated NaOH KOH they are slowly consumed, if the solutions are diluted they resist enough.
@@claudiohomelab8181 I thaught that they may react with the glue. Anyway awesome work.
A very interesting study. I studied the issue of the use of hypochlorite and aluminum for the production of electricity outside the house. Solar panels cannot always be used. I used foil, since its surface is great for sufficient current strength. As another electrode, I used stainless steel or titanium. The element voltage was 1.8-2 V without load. Try to use noble metal or inert metal. Perhaps a thin layer of platinum applied to a polymer film with a large surface. I also believe that you can use a large concentration of hypochlorite.

It isn't rechargeable. It works better if you use a cathode of a metal oxide or salt mixed into pressed graphite. Bleach is doing more or less the same thing as NaOH since it has a lot of NaOH in it to stabilize the NaOCl. What you want would be to have the anode donate the oxygen to react with the aluminum but make the electrolyte as unreactive as possible with the aluminum because the hydrogen made quenches the voltage output. An aluminum/manganese dioxide-graphite in propylene carbonate will generate a bit over 2.8V.
Add carbon too system too store power....I took one piece off charcoal put foil around it soaked in salt it gave off power for weeks...not even charged...the power was low but the principle is there
