  • In this video l will tell and show you how to make a Supercapacitor at home. It will be 1.4 V and 200 farad. I used copper foil, graphite powder and activated carbon. After making Supercapacitor l test it. It works very well. It charge and discharge very fast. #supercapacitor, #capacitor, #battery, #diy, #homemade, #graphene, #graphite, #activatedcarbon, #activatedcharcoal

    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!

      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.

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?

    Thank you very much for the video!
    Very informative!
    I would like to clarify. I correctly understood that for the preparation of the active mass you used:
    1. 9 grams of activated charcoal powder;
    2. 1 gram of graphite powder;
    3. 10 milliliters of deionized water;
    4. 1 gram of PVA glue.
    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 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

    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,

    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.

So when the level of electrolyte decreases some pure sodium hydroxide will remain on the electrodes and it will start a chemical reaction and it will cause self discharge and ruin your Supercapacitor overtime.
