This will be a game-changer for electric subway trains that use friction-braking to decelerate (in some places the third-rail doesn't support regen-braking) - no more PM2 dust!

Hmm. What would be amazing is if we could find an near-perfect insulator that's also 1 atom thick. Li Ion batteries are made as a 'jelly roll', meaning there's one long strip of lithium on a substrate that is then rolled into a barrel. The problem with a graphene supercapacitor is that the stuff between the graphene isn't 1 atom thick. If we can find that 1-atom-thick insulator and find a way to bond it to a single layer of graphene, stack two of them and then roll all of that together in a jelly roll, then we'd have a super capacitor that's on par or better than standard Li Ion batteries.

Supercapacitors are the perfect buffer for batteries. Supercapacitors can enable faster charging by evening out the charging curve, absorb more energy from regen, faster acceleration. Especially city driving will benefit *a lot* from supercapacitors. Only a few percent of the battery need to be replaced by supercapacitors, and lower performance battery technology like LFP benefits even more by them.

Trican uses their automotive version to start 16L engines. I have personally installed them about 200 24V skeleton caps in the past year and they all work great 👍

Supercaps are a pretty cool technology. We incorporated some of the very first high-capacity capacitors a few decades ago... a whole 1F. We used them to backup static ram chips and real-time clocks. They could keep them going for a week(!). That way, no lithium battery on the board that would have to be replaced every 5 years. These days 100F is common. The problem is still storage density, though. I can see them being used, in particular, in energy recovery systems. But I think we are a long ways away from being able to replace chemical batteries. -Matt

I sometimes feel like Graphene is becoming the Fusion energy of the Materials world, we know how to make it, we know it has revolutionary potential, but we JUST CAN'T QUITE FIGURE OUT HOW TO MAKE IT COMMERCIALLY VIABLE!! It's Very Maddening!!

You went with this video exactly where I was thinking: combo of super capacitors and batteries is best depending on the niche problem being addressed. So great to see some level headed thinking on YT rather than more blind hype saying that we found a “one size fits all” solution for all our problems!

Nobody ever seems to mention the dramatic potential of super capacitors to enhance hill climbing in EV’s and hybrid vehicles. In normal driving, going up hills sucks battery capacity more than anything else. This would be the perfect time for an electric motor to get that quick burst of energy to get up a hill and saving the battery for flatter terrain. Combined with a stored digital terrain map, the energy management system could tell a car when to pull from the capacitor when it’s about to go up a hill.

I've installed one dozen super capacitors for my car audio setup along with an agm battery and high output built aftermarket alternator, big difference in power output and it's super steady for around 3,000 watt rms output to subwoofer. I'm still testing after almost two years bumping on them, so far better then just batteries with an alternator.

I thought there was nothing more to know about the state of graphene super capacitors, but this was the most clear, to the point, no bs, honest truth and realistic use case graphene video I've seen, ...and I've literally seen them all!

Very good point about buffering! All it takes is for someone to turn on a shower or kettle during peak load to stress out a home battery.

One of my Star Trek-ian dreams is lightning rods, with giant high-speed switching arrays, and banks of supercapacitors, to absorb the energy of lightning bolts. Lightning strikes 50-100 times per second, somewhere on the Earth. If we only had a network to absorb and distribute the energy around the globe....

your video was of informative and helpfull for me and now i am doing project on it too all thanks to u sir plz keep the good work

I’m glad to see that you did a video on supercapacitors, I’ve been thinking they have tremendous potential that hasn’t been much talked about. Regarding ludicrous mode, it seems to me that they might be useful even in regular driving. When you accelerate from a stop, even if not accelerating rapidly, you’re still using more power than when you’re going along at a steady pace. If super capacitors provided the extra energy for acceleration from a stop, perhaps battery packs could last longer and maybe the electronics connecting the battery pack to the motor could be simpler.

Thanks, been waiting for these two breakthroughs to make t to general public; you’ve done it!

Capacitor voltage drops linearly with discharge and supercaps are usually low voltage so a complex DC to DC convertor is required to use them along with battery packs, which usually makes them a consideration for larger systems with batteries, but not smaller ones.

_This Graphene SuperCapacitor Breakthrough is HUGE!_ No it's not, Amber.

Super caps on Perovskite solar panels? That could really make a huge difference in the potential on every roof.

Thank-you for being real and clear about what capacitors can do. I've had people trying to tell me that ultra-caps are achieving the same energy density as LI batteries. I simply told them, "I don't think so.". But, here's the proof. Yes, I think it's a good idea to use them to take up the surge from starting and stopping a vehicle, but not as a substitute for main energy storage.

Ricky, Very Exciting near-term tech! Great report! Cheers, Eric

I agree we need to diversify storage for electricity. I see these being useful in where there is a surge on your home battery system when your air-condition unit starts up. Air-conditioners have a start up capacitor in them already but adding one with your battery storage would extend the life of your batteries. Keep in mind your AC starts and stops several times a day and surges every time it starts.

Excellent video! Thanks!

The 72% increase in power over time plus the recharge rate increase is a big step. The critical advantage the supercapacitor presents is the start and stop applications. The locked rotor startup requirements of all motors could benefit from the Skeleton technology.

I use whole bunch in a capacitor bank in a parallel/series configuration as a buffer cycling between 32V and 60V on a solar power system they give me about a kilowatt hour of buffer. It switches loads between grid and inverter based upon the voltage of the capacitor bank. They are Maxwell ultracapacitors, bought used from old hybrid buses about ten years ago. In this application with slow cycling and low current draw per cell, they are still functioning. Aside from two I messed up because they were in a block of 24 (4P6S) I pulled off to jump a vehilcle and accidentally reverse charged them, they are all going strong. Those two still worked, but the internal self discharge became high enough to through the cell voltage balance of the block off, so I replaced them with spares. I believe there are about 422 ultracapacitors in that bank. Mostly a mix 3000F 2.7V and 2600F 2.5V cells. I have a couple more on smaller solar power installations. They are much more tolerant than batteries and if the system goes down for a time because of snow on the panels and such, these don't really care about low voltage if there is nothing or no one around to charge them up with.

My first thought was a series of books by Philip Jose Farmer, "Riverworld". In the books, there was a device he called a "batacitor". It could take in huge amounts of energy almost instantly (like a capacitor), and then discharge it slowly like a battery does. I liked how they could be used in conjunction with solar panels to "smooth out" the electricity going to you charge controllers.

I put super caps in parellel with my ebike battery 13 years ago and i could take off faster for sure. probably 30 % or more. I never timed it as i was just happy my concept proved itself without a doubt in the real world. I have a 4000 watt scooter now and i will be creating the same concept for that. I predict about 6000 watt peak at take off. i definitely will be taking many measurement with that concept and posting on my channel.

Respected video sir, excellent invention. God bless you and your team and world

Super capacitors are really cool! I did a lot of research on them in high school when a group of us were working on a hybrid car design project. Back then they wernt made out of graphene and we’re about the size of a can of pop.

Since I first heard about ultra/super capacitors, I have been dreaming about a hybrid system of battery and capacitors just for the reasons you explain, mostly regen braking and acceleration.

You did a good job with this video. Some people have replaced their lead acid car battery with a super-cap pack for starting their car. I think they would be perfect for electric trucks. For starting to move, as well as added power on steep hills. If designed right, they could replace the large oil filled capacitors at substations.

Love your site! It seems to me with the right supercapacitor on a ev in stop&go driving in a big city with regenerative braking you could drive almost indefinately.

Because of their lighter weight compared to batteries, another important use case for these graphene capacitors has got to be aviation. Air-breathing ion thrusters, although a great idea, will require an extremely high voltage to achieve full TOGA thrust - a voltage that only something like this could provide.

thanks for explaining charge density in a sane understandable way.

Really good video! Super caps sound great for motorcycles! they might also be good for robots. the old lawnmowers use capacitors to charge up super fast in order to creat that spark plug spark. You might want to demonstrate that. Old tractor magnetos also used capacitors. if you put a resistor on the exiting circuit they can e slowed down. A 555 timer chip and a capacitor and resistor can be used to fire a 12 V DC old car starter solenoid from a 1-1/2 volt battery.

If you look at the energy demand of an electric vehicle you will see that from stop to moving is where most of the energy is used. It follows the Newton's law that basically says an object at rest remains at rest. Going from rest, that is not moving, to moving has to overcome that inertial force of the object not wanting to move. Capacitors are great at providing bursts of energy, so their use for overcoming inertia is perfectly matched. On the flip side Sir Isaac Newton says something to the affect of an object in motion remains in motion. So, trying to stop a moving object takes a bit of energy as well. Our regular friction brakes work the same way that pressing a stick against a moving wheel eventually stops the wheels movement. It does this by converting the motion of the wheel, its momentum energy, and converting it into heat through friction on the stick. The heat on the stick heats the air around it and the energy that used to be momentum energy has now turned into hot air. This way of braking is completely wasteful. With electric cars we take the momentum energy and convert it into electric energy through the motor by making the motor a generator for this purpose. With lithium batteries the amount of energy that is created by the motor/generator comes too fast for the lithium to do the chemical changes to absorb it all. Here, again is where capacitors shine. They can take in electricity really fast since they use a magnetic field to store electricity rather than a chemical reaction. With the capacitors now charged by regenerative braking, that energy can be used to get the stopped EV moving again. This rocking back and forth from capturing braking energy and then using that energy to get going again means that the batteries will be used mainly to keep the EV going once it is on its way, dramatically increasing its range. And, since the battery won't be discharged and recharged at the high rates that getting going and regenerative braking need, the wear and tear on them will be much less, making them work better and last much longer. Capacitors, supercapacitors and ultracapacitors are great, and should work fine for the stuff I talked about above, but, if graphene capacitors can be made inexpensively, their contribution to this setup, because of how little space they take up could be huge.

Been hearing about graphene and sulfur batteries for years now. When can I open my presents already!?!?! too excited to wait any longer

For those who are familiar with the inner workings of computers, the difference between a capacitor, super capacitor, and a battery is similar to the differences between cache memory, RAM, and HDD/SSD. If they don't already, as suggested in the video, makers of house batteries, like Tesla, should be incorporating capacitors and/or super capacitors into their batteries in order to reduce stress on the different components by having each perform the role they are best at.

Nice info, thanks for sharing :)

I just wanted to mention LTO batteries. They're a battery that acts like a capacitor. It's about twice as energy dense as lead acid batteries, low for lithium. They advertise 20C or higher discharge rates, and 20,000 charge cycles. I'm currently using one for a car battery. Definitely too expensive for grid use, but good for certain niche applications.

Hello Two Bit da Vinci and thanks! I got mine, for testing purposes, directly from China. It's a 100,000 Farads. The contact terminals are screwed-on half inch bolts on either ends. They must separate them to avoid arc'ing. It's only 3.7V but the potential amperage is humongous. It weights about 2lbs and is 5 1/2 inches long, and 2 3/8 in diameter. Yes, they are rather expensive (still less than $200 each) as they are built with rolled up graphene. I just completed a project for the mighty Thor and Jane Foster. Mjolnir had to be put together again and it worked out pretty well (if you haven't seen the movie already)! Okay, the first part of this is real, the second part is fantasy-ish. Love your channel. Cheers!

Great presentation!👍

Well done, thank you!

I am anxious to see electric car circuit races. This will help to refine battery and super capacitor technology.

It’s great to see graphene finally starting to scratch the surface of its potential

9:18 they already have a 12v battery, no need for capacitors. Where capacitors would be useful is as a buffer for the main pack to soak up moments of high charge or discharge.

Supercapacitors for EVs are what nitro is to ICE cars. Not sure you mentioned it, but it's great for big trucks too, as it allows them to start much faster from a red light or a stop sign, for instance, so it does not slow down traffic in cities. You still need the motors that can withstand the effort, but it spares the battery pack a bit. In 10 years time, such supercapacitors may very well be present in most everywhere.

There You Go ... Graphene Super Capacitors

If you make the supercapacitors tall you could use it the magnus effect to propel a ship. This would mean the supercapacitor is rotating and producing lift/force even when the wind is not blowing. The magnus effect is more when the wind has more speed.Also you could use it on chimneys since the charge could be used to remove pollutants from the air.

i use both lithium, battery pack and a super capacitor pack in parralell of the same voltage on the ebikes we make,makes a world of difference with charging ,regenerative charging and voltage stability

I should point out that neither of the cameras shown had any built-in flash facilities. For both those models, a flashgun was a seperate item that had to be fitted on. Also, a flash "bulb" was a different item altogether. It was a single-use device. It could flash only once to light the scene, and was then thrown away.

Supercapacitor rapid wireless chargers at every stop light, stop sign, and crosswalk, drive thru window, parking stall etc. basically, any time the vehicle stops, charge it wirelessly. Also, yes I understand how amperage loss works over distance BUT, if we ran a giant extension cord across the Bering Strait to Russia and China etc, we could take advantage of the Earth’s 24 hours of solar power (the earth spins) and I’m sure we could daisy chain some supercaps at power distribution stations along the way, and store generated energy. After all, we sleep at night so we need less energy at those times anyways. No reason we couldn’t just share the sunlight

Excited for power tools to use these.

I just built a 6 cell 12v starting battery for my vehicles from 3000f Maxwell Ultra caps. It will start my semi truck or diesel tractor with ease. I put welding quick connections on it so.I can transfer between vehicles. It was expensive, but only needing 1 "battery" saves about $120 per vehicle.

I use ultra capacitors with lifepo4 in my car audio projects. They do very well working together but I'd love to try graphene

Adding a super capacitor(stage) to an e.v. powertrain would give the smallest battery e.v."supercar" performance.The capacitor would hold a bucket full of energy and dump it all at once when acceleration was demanded. Then recharge immediately upon regen braking or more slowly from the battery once depleted.

Graphene used on a commercial scale is always good news!

Very exciting! I hope this potential is realized.

That type of storage could boost the margin for wind deployment in places where the wind is more prone to gusting, such as around mountains and islands.

The voltage of a capacitor is linear to the charge which has both advantages and disadvantages. I can see there being hybrid devices, basically batteries buffered by a capacitor, maybe even a betavoltaic nuclear battery buffered by a capacitor.

When explaining the power density of Li-ion and Supercapacitors, you used Wh per KG. Wh are a measure of energy. That's why you use the same units when explaining energy density later on.

Do a deeper dive on how super capacitors can improve solar panel array performance. Include issues like deep well pumps (that use two 120v inverters) is hard for many off-grid situations and AC systems which are mostly covered by soft start boxes.

at 10minutes 52 seconds into the video is pictured a system of Kilowatt Labs, "Serious" energy storage units, to be clear the inference is that these devices are super capacitors, well with a little research they are in fact repackaged LTO energy storage, ie Lithium Titanate Oxide batteries which by co-incidence have very similar characteristics to earlier super capacitors but certainly not a advanced as the Skeleton super caps, cheers, Dean, Vic, Aust.

Great video!!! Exceptionally clear in explaining the entire graphene-based supercap landscape and how the Skeleton batteries can (if they are successful) be a major game changer! Thank you!!

Really good well explained video. I saw an idea from BMW many years ago to add two super capacitors in the car sills to add boost to a ICE car and reduce fuel consumption. Can't help thinking that Graphene capacitors would really help in PHEV vehicles and mild hybrids as this would reduce the size of the battery and increase hybrid efficiency. Used in the acceleration phase to preserve battery power, which could be used on cruise mode. It could be charged up as indicated with braking and trickle charged from the battery. Suspect would only need just a few Ultra caps. Batteries do weight a lot as well. The energy cost of creating a 100KWH battery adds 20 tonnes CO2 compared to a ICE car which is 8 years to break even. Also would be really useful in fuel cell cars as they create a constant flow of electricity and presently use a battery for extra power for hard acceleration and this would also be a benefit as the battery could be smaller and instantaneous power would give extra power. I see this as a good addition to BEV, PHEv,, MHT & FCEV. Could also help with aircraft to reduce fuel on taxi, takeoff and climb, the most wasteful part of flight.

Exciting stuff!

I think flash Joule heating of carbon has a lot of opportunity to produce graphene at a high rate of speed. Feb 2000 paper on this approach somewhere. Use air centrifuge to colloct only those particles that have the correct mass and size. Particle separators do this now... Charge these particles electrically and mix in a hotargon- carbon monoxide environment - that is one way to "kink" them. It should produce a particle combination of graphene and graphene oxide, distorting the flat shape. Spray this onto a film with a hydrophilic surface and roll it into a package. That would take a lot of engineering, but it is a continuous flow process where each of the steps could work in an extremely cost effective way.

these technologies are worth the effort

Great video, any idea how Skelcap solution compares with the solution developed by GMG?

Good presentation. Another comp to look at, Cap-XX from Sydney Australia, supercaps the size of postage stamps, 0.4mm thick, LICs, also planning thin graphene supercaps 2024 (joint venture Ionic Industries, Aussie graphene producer)

I have been a fan of supper caps for 10 years now. I worked on a project that used super caps for a small robot that would make short runs between charging. Like the Rumba.

The guys doing Atmospheric energy collection talked about capacitor storage for this collection type, since the electricity comes in immediate spontaneous spikes.

from electrek July 2021: "Back in 2019, Tesla announced the acquisition of Maxwell Technology, a San Diego-based ultracapacitor and battery company, for over $200 million. While the company was mostly known for its ultracapacitor business, it had just developed a dry electrode technology for battery cells, and Tesla revealed that it is what the automaker was really after. Tesla used the technology in its 4680 battery cell unveiled last year. Two years later ...Tesla...sold Maxwell’s ultracapacitor business to UCAP Power, another ultracapacitor business.

The drag racing application should be very entertaining!

It's always about being able to mass produce,I'd like to see some special tech prototypes

Excellent! I wonder if they could be used on drones equipped with extremely (“blindingly”) bright LED strobes to incapacitate persons and/or animals who are where they shouldn’t be.

Ricky 🤗ACTUALLY THIS HAS BEEN MY LIFELONG DREAM 💭over the past 50 years and now we have the opportunity to make it a REALITY 🤗…so progress with graphene is NOT that far away and PROGRESSING QUICKLY…so IMHHO we just have to be patient and it will happen 😎😍😍😍

I'd like to try these out on my amateur radio venture out doors.

I'd be interested to see the home storage solution. Would this be good to run some of the appliances I have and use it in conjunction with safer and non toxic batteries out there?

Can the super capacitors be attached to external battery bank (2nd Battery system), be charged via solar or, car alternator via electronic solenoid.? Example: I have a second SLA battery system for my van. Currently is charged via main battery though, electronic solenoid and I can attach portable solar panel through 10 amp controller. I have a 1500 watt PSW INVERTER connected for any none 12v electronics. HOW CAN or will the super capacitors like you have there be attached, be charged via solar or electronic solenoid, and it's benefits.?

Is it, is it finally here?!

Regarding the regen - are you sure the regen is currently capped because of battery charging time or because of the fact regen braking will never be able to stop your car similar to braking. You also mentioned how having sc in cars would increase the milage but what's the point you can get more mileage having them supported by li battery.

YES! Combining batteries with supercapacitors is the way to go. Combining them both into vehicles and providing in-pavement fast charging areas at urban intersections would reduce battery needs and also reduce significantly the need for stand-alone charging stations.

I think if they could make them for the automotive audio bass world, that could open the door to another market. Super cap. Vs. standard cap. I’d bet the top Db’s competition users would help that style capacitor be tested and helped to the market faster. Just a thought.

Can’t wait to see this hit the market, hope it will be affordable, it will be a game changer for many applications. Thanks for your info and efforts with ur vids. Cheers

I think if Skeleton Technologies and their competitors get products ready, it will be seen in high performance EV area as it will allow very high peak power and still less heating and the less cooling. Also less use of break calibers when racing, so breaks are actually used they work reliably. Again less overheating. In cold weather supercapacitors would allow regenerative breaking at any temperature and any battery level. Industrial usage would be huge as any process that needs much more power during startup period than normally would benefit greatly. Skeleton Technologies example was just diesel truck, supercapacitor is more reliable way to start than normal battery.

You did not mention current and projected future cost per unit of storage (Kwh). I know costs keep going down, but are they anywhere close in cost/Kwh to Lithium ion batteries?

i'm wondering where those number at 11:18 come from! a PV system doesnt produce random surges you'd have to buffer with supercaps

Application? Aircraft. Maybe not so much for cruise, but during the descent mode.the opportunity to recover a large amount of energy in a slowing descent and then release it as a "turbo boost" during takeoff would seem to be useful?

Nice video, do graphene manufacturing group next please!

Supercapacitors have the potential to be used in concert with less reactive battery chemistries to provide short bursts of power without stressing or cycling the batteries rapidly; ditto as a regenerative braking near lossless energy recovery device. Until someone like Tesla builds a prototype using real-world batteries and supercapacitors in a roadworthy car, we won’t know whether they are a practical technology for automotive use.

I found by casing a cap in ferrous metal, it can become a transformer of low frequency. Graphene can be made using co2 at 1800f 10% atmosphere over a film bombarded with positive ions

Put supercap and bettery in the same cell. The cell rapidly reaches the charge voltage for say 10% and avoid short high current bursts to the battery substrate.

Further research in this field is very much appreciated, required and necessary. Large and cheap storage is the real missing link in renewables. I don't think lithium batteries are the solution to this problem because they consume far too many precious resources. Large capacitors may be the answer.

If only there was a supercap that could easy aftermarket install mod to “any “vehicle to breaks to regen into your 12volt car battery just a fraction higher voltage than your alternator cut in voltage then it at least would run your spark plugs ,radio & AC . . . . that would be a gamechanger !! Even better to then dumpload into a set of tool batterys in a work truck and have them recharge before you get to next worksite, this would be a dream come true for me!!😎🙏🏻

Wonder if elevators are a good application of super capacitors? Another great video.

It makes home solar a lot more efficient during the day when the sun is shining most of the power being produced is powering the house and charging the batterys at the same time. It dosen't take much to power a home unless you turn everything on at the same time.

How does Electrochemical cells(such as lithium oxide battery), supercapacitors and magnetic storage compare per kilogram. Curious.

one way to think of super capacity and battery as memory in computer and RAM and hard drive space (SSD). The fact that super capacity has no memory and fast is THE KEY

At the 4:48 you showed a field of solar on a wooded hilltop. Where is this? Thank you.
