Can you make a supercapacitor from kapton tape? Yep! Using a laser, we can decompose the Kapton (polyimide) into a graphene "foam" via a process known as Laser Induced Graphene. This form of graphene makes an excellent material for electrostatic double-layer supercapacitors. It has reasonable conductivity and a very large surface area due to the foamy nature, which allows good contact with the electrolyte.

I realized my explanation of how these work was vague and poorly worded, sorry! Graphene-based supercaps are a form of electrostatic double-layer capacitors (EDLCs). Charge is stored at the interface between the electrode and electrolyte via electrostatic attraction when charged. Due to the small charge separation EDLCs can charge and discharge very quickly, and the extreme surface area of graphene foam gives a large interface with the electrolyte to improve overall capacitance. That's why the "perimeter" of interdigitated electrodes is important, because more exposed perimeter == more interface opposing the other electrode to accumulate charge.

What goes into selection of optimal electrolyte? What gives kapton tape this property of UV -> graphene? Could you estimate your capacitance economy? Like capacitance per area, volume, dollar, time, etc?

@ScottGrammer 3 жыл бұрын

Is this why you use an acid for the electrolyte rather than say an oil like in electrolytic caps? Because the electrolyte must be somewhat conductive?

@TheVideoGuardian 3 жыл бұрын

One other point on you're value measurements... It is not uncommon for capacitors to be manufactured under "tolerance" of 20% or more, so the meter might not be as inaccurate as it looks.

Your capacitance meter is likely more accurate than you realize; most commercial capacitors have a fairly wide tolerance from their stated value. Manufacturers data sheets should list the tolerance for each type the produce.

And the tolerance rating is often kind of 'skewed'. Something like +20/-10% of the nominal value is common.

Agreed. One of the caps he tested looked like it was rather old (the 5uF unit). First, if it actually was rated 5uF, it really is old, because anything made after say, 1975 would likely have been a 4.7uF, not a 5uF unit. Anyway, old electrolytic caps tend to become leaky, and leaky caps often read high on capacitance checkers, even though their true capacitance is falling.

Great research and presentation! The applications for this technique are huge! I'm an electronics engineer. And I think there's a possible fault on the capacitance metering. Multimeters presume you are measuring a capacitor, but electrodes in a acid medium will make a resistor(or RCL equivalent circuit), also may be electro-chemical reactions going on. There is no insulation on your device and electrons are flowing between terminals. It will probably self discharge almost instantly. To measure a capacitor precisely you first need to charge it, disconnect from source, than connect it to a load. Integrate the power it produced and you will have the energy it is able to store.

@BreakingTaps 3 жыл бұрын

Ah interesting, does that apply when using a dedicated "capacitance meter"? I had assumed/hoped it had internal circuitry to power the cap to some degree and test it's leakage or something? This is the device I have: www.newark.com/general-tools/cap1500/capacitance-meter-digital-200pf/dp/59P4162 I did find that it self-discharged very quickly just sitting on the bench, and made even worse when poking it with a multimeter :) I'll see about setting up some kind of circuit as you suggest to test it. Thanks for the help! Electronics is definitely not my forte, very much a newbie still :)

@odudex 3 жыл бұрын

@@BreakingTaps Hard to tell what process it uses to measure. But I think you don't have a capacitor(yet). You need an insulating medium between electrodes. For example electrolytic capacitors use aluminum oxide. In a capacitor electrons can't flow between terminals, there should be an insulation, where an electric field will be created to store enery.

@BreakingTaps 3 жыл бұрын

@Eduardo Schoenknecht So big grain of salt due to my general ignorance, but my understanding from the literature is that these types of supercaps operate a bit differently. When charged, a helmholtz double layer is formed symmetrically on the electrodes using the ions in the electrolyte (graphene + | - electrolyte + | - graphene), so there isn't actually a dielectric in play here. Just ions associating / disassociating with the graphene at the interface between liquid and solid. In theory, based on my reading, but as I said I could have that incorrect :)

The first LIG papers were done on CO2 iirc, and there are some neat followup papers where they perform multiple passes to turn amorphous carbon into LIG (which isn't possible with shorter wavelengths like mine). Was used to make supercaps on coconuts and potatos as demonstrations :) I wonder if that's why yours was blacker? The literature shows that LIG is a big mess of graphene + amorphous carbon + fullerenes + tubes, so I wonder if the CO2 does a better job of converting some of the non-graphene into graphene? Dunno, but interesting result! No discord at the moment, but I was just thinking it'd be fun to have a place to gather folks working on similar stuff. Lemme set one up and I'll give you a ping!

The bed heaters on my 3D printers typically have kapton covering them. They also suffer from being inconsistent and take a long time to come up to temperature with DC power (less so with the AC bed heaters), with less heat near the outer edges. If the kapton covering them were the actual heat source then I imagine it would perform MUCH better. :)

@anttiandreimann8456 3 жыл бұрын

I immediately thought about the same thing. Aluminum is often used to spread the heat from the wires of a heater. Lot of the heat is lost to the backside of the plate. So what if you had a glass bed, completely covered with kapton tape and a standard PEI sticker on top of that. Glass is more rigid than aluminium, has lower density, is a fairly poor conductor of heat and even cheap glass sheets are usually flatter than aluminum. So one can have a lighter, more rigid and flatter bed, reduce losses from the backside and get a more uniform heating. Manufacturing this should be very easy too. Just apply kapton tape to the glass, treat it with a laser, run two pieces of copper foil on the sides for power, then apply PEI sticker on top. Or, perhaps a magnetic sticker to enable the use of removable flex sheets.

@@AlexanderTzalumen to try it out crudely there's a simpler solution, since the resistance of the "heating mat" shouldn't vary too much with the temperature swings (at max up to ~100°C of swing from ambient, for general 3D printing with "normal" materials) you could even characterize it measuring the temperature with a thermocouple vs PWM percentage of current, and then control it just by using a look up table and not even need a PID controller, as a certain amount of PWM controlled current should provide the same temperature consistently. Although thermal imaging would be necessary to ensure the current is not traveling in just a straight line or area of the mat (think skin-effect) as opposed to through the whole mat, because PWM-ing creates a lot of high frequency harmonics which may (or may not) induce this effect. Might give this a try one day if I get myself a laser, hope someone beats me to it because it sounds promising IMHO

@AlexanderTzalumen 2 жыл бұрын

@@markopesevski perhaps, but the marlin firmware used in the majority of hobbiest and consumer 3d printers all use PID controllers for their heating elements, partially for the initial temperature ramp, and also for maintaining temp stability against the various sources of heat loss (radiant losses, ambient air currents, part cooling fans, moving build plate, etc). For a heated build plate, inconsistant temperature can lead to 1st layer delamination, which will cause the print to shift, warp, or fully detach.

A note on the capacitance meter: electrolytic caps tend to have a very generous tolerance range, skewed up, since for the most part they're used with rectifying circuits for their relatively high capacity. There's a possibility for the real capacitance value to be closer to the meter readings than to the value on the label.

capacitance reading may be off in this case due to high leakage resistances, you need some type of rlc meter to determine simultaneously Parallel, series resistances AND capacitance. Parallel Resistance is responsible for leakage currents -determines self discharge speed actually, while series resistance is like a series connected resistor - limits the current and has other detrimental effects. But anyways with some clever experimentation I think you can figure out all of them. nice job.

Just wanted to offer up a big *Thank You!* For your hard work and effort, and for your desire to propagate knowledge which I feel is a noble cause, and can only make the world a better place! If only more people had that same desire, or even the desire to learn, frankly. It seems nobody wants to learn, they just want to *know* if that makes sense.

I just stumbled upon this amazing video by chance. I'm hooked! Do you mind disclosing the make/model of the laser engraver, as well as the laser module that you use? Keep up the good work!
