How Supercapacitors Work - A step by step guide

[@pauldebruyn5052]

I,'m a retired 80 yr old industrial electrician who get my electrical knowledge from Audels Electrical libraries. (qv). You have brought head shaking awe with the new stuff to this old bird. Thanks a lot,I'm buying a Noco for my garden tractor ( 20 HP single cylinder engine), It needs a big battery, but this Noco puppy will solve the problem and a handy trunk item in the car as well. . I'm wondering what you're going to write about in 60 Years. P.S. I apprenticed with an Electrician Master Journeyman Frank Owens 1n 1959. He had been John Logie Baird 's Apprentice in Scotland . Mechanical Colour Television Eh What Lad.!!! Thanks Again.

[@abo3abid1]

You explanation was very clear and concise. Please expand on the potential uses of the newer high capacity SuperCapacitors

[@EVTechExplained]

Thank you for your comments! Newer supercapacitors do not have a step change in energy density, thus their uses are unchanged. One of the most interesting mainstream uses of supercapacitors recently has been the Samsung Galaxy Note 9 stylus.

[@2011italianoboy]

Great video and thanks for the links. I currently have Dyna-batt manufacturers ID 5575B. It's a 12V, dry cell battery, 16amps hrs, and it is 4 years old. The CCA on it is around 280 and I live in NE and on days where its under 50 degrees, the car struggles to start. I want to maintain the weight savings and I like the idea of a supercapacitor, in parallel. What kind and how many would I need to help boost this battery? A schematic, or links to what I can buy would be awesome. Thanks!

No. You can not. The whole circuitry will have to be changed and in the future you may find capacitors are used instead of batteries.

[@seasidescott]

Thanks for your time. Definitely interested in combined capacitor/battery. I use a lot of cordless tools and those that require high draw startup or occasional high amp (saws) that seem to deplete batteries very quickly. Then two hours to recharge. Wondering if the capacitors would help?

[@SavageStormAir]

They certainly would. You could combine your batteries with the supercapacitors; as the supercapacitors would provide the bulk of the power, the batteries can operate in a more efficient region and hence last longer, and continue to function over a wider SoC window. Lots of power tool companies are looking to integrate supercapacitors into their energy storage systems for power tools.

[@sandeepgodolo6970]

Thank you for such an lucid explanation. There are new developments which allow super capacitors to replace lead acid or lithium ion batteries. Can you shed light on that.

[@marxnutz]

Is there a way to translate a supercap's stats to an equivalent of battery power? I ask because I would like to learn what would be required to replace a bank of batteries in an off-grid set-up with supercapacitors.

[@EVTechExplained]

+Tech Help A lithium ion battery will typically have a maximum voltage of 4.2V and minimum of 2.5V, with an average of 3.6V. A supercapactitor typically has a maximum voltage of 2.7V, and voltage decays linearly to 0V.

[@E9Project]

What I need to know is the proper mixture for the ionic solution, when using KOH "potassium hydroxide" I dont know the correct portion of DI water and KOH to use. any help would be greatly appreciated, im trying to make some working cells at home to learn more about supercapacitors and to do some research and development.

[@ZephyrCorsa]

Similar concept to torque and power in ICEs. You can have more working force being put out at a slower rate like in a diesel engine (high tq, low hp) or high output rate and low to moderate working force like in a performance gasoline engine (low to med tq, high hp). Like comparing Lithium ion cells to a super capacitors.

If you could slow the rate of flow of electrons out of a capacitor couldn't it then be used as a replacement for batteries?

[@EVTechExplained]

+MARTIN STRANGE Not really. Fundamentally, you store far less energy.

[@SameerKhan-xf6vq]

I have recently made a youtube channel, and i kindly request you to please check it out Thanks for your generosity.

That is correct EV, but again it is the rate that the electrons are released from the capacitor. You would need many of these but would be far safer and longer lasting than lithium Batteries.

[@blg53]

The "rate of flow of electrons" is not dictated by the source of energy (a battery or a capacitor), but rather by the consumer of energy that source feeds. For example you can have a 5 Watt phone charger and 2000 Watt electric heater, both require identical voltage to work (let's say 12 Volt). You will find that the latter will produce much higher flow of electrons that the former from the same source discharging it faster. That what makes batteries and capacitors suitable for some applications and unsuitable for others.

[@juancarloslozano3374]

Following the Mazda 3 example, I would likr to know how this is used/applied on a eolic turbine application, could be a great ilustration and massive use of super capacitors

Thanks the explanation was vivid

[@jpjay1584]

what is more suitable for a portable heating device? Liion batteries with enough Amps or Liions + super capacitors? lets say the heaters needs around 500W. with enough batteries that should be ok. but what if I need 700W or more, can I add a supercap to the Liions and "charge the cap" so it delivers 700W? Liion. 36V with discharge15A = 540W Liion. 36V with 15A = 540W + supercapacitor...... can this now deliver 700W ? possible?

[@EVTechExplained]

It is possible but would ultimately be bigger. I think a battery only solution might be best in that case

[@jpjay1584]

thanks!!! for my understanding: the heating coils would draw 15A from the batteries. (at 36V) would they also draw 15A from a Capacitor or would the capacitor "deliver" more amps (lets say 30A) and heat them up faster? which specs should a capacitor have to deliver 36V 15A-30A? (for 10minutes)

[@walterhartland4472]

so it will over heat because it cant discharge fast

[@uwepolifka4583]

Nice Video and good explanation but I miss the explanation why all supercapacitors are limited to 2,7 Volts. Why is it impossible to build single cell supercaps at 10V or 30V ?

[@EVTechExplained]

The electrochemical stability window of the electrolyte prevents higher voltage being used. At 10V, the electrolyte would breakdown, causing gassing, and irreversible capacity loss.

[@uwepolifka4583]

Thank you very much. My idea was also that it must be a limitation of material but I don´t know more.

[@punker4Real]

it's currently limited to 3 volts ultra capacitors You can build a module that is 10 or 30 volts (in serial ) you will need a lot of them in parallel for HIGH capacity

[@Dougwoz1]

I have worked in electronics and as an electrician my whole life. And to this very day I still do not know how to determine which capacitor to use. I've always just had to replace them with the same type. But determining which one to use for a project has always baffled me. Is there a good video to understand the concepts of using capacitors in place of batteries? With specifics in determining the power output and voltage - in relation to capacitance?

[@sonaruo]

a capacitor has 2 numbers the voltage and the capacity so depending how the circuit is build you can replace capacitor the some voltage and if you have the space you can go for higher capacity it the same as batteries when you replace a battery you need the same voltage but you can always put a bigger one in amps

[@davidmayhall6567]

I suggest A mechanical energy storage Device be fabricated in the system a motor generator flywheel assembly gimbally mounted. This instant storage device will take as mutch power as you can hit it with from reverse electric braking or turbine generator overflow. A voltage regulator and combined with supercapicitors would be a perfect set up for a auto a race car a airplane a helicopter. Energy can be instantly pulled from the gimbally and directed into the drive motors.

[@kauguy100]

can super caps be used to charge batteries?

[@EVTechExplained]

Yes, but they store much less energy, so many supercapacitors would be required to charge one battery of equivalent size

[@michaeldeneka8685]

[@BillAnt]

There's already an e-bike on the market in Europe utilizing a hybrid super-cap and LiPo battery. The super-cap is used for very efficient regenerate breaking capturing up to 90% of the energy, for which batteries are not well suited due to their slower charge rate.

[@EVTechExplained]

+Don Clavecilla Definatly available in Asia right now. It is often used for smartphone camera flash and can be done in very small sizes. An alternator can charge this as it does in the Mazda application, however this would not be perpetual energy as kinetic energy will be removed to generate electrical energy.

If you have a material eletrodo with a low superficial area, you are gonna have a lower power density. However, one of the main things comparing to batteries what makes capacitor interesting is its power density, so I think it is not a good idea of decreasing it. I don't know if I could help you.

We know a capacitor can be used instead of battery. Then why not a super capacitor can be used as battery! if do what are the limitations.

[@flyguille]

because a battery would be like 3.000.000 farads.... but a supercapacitor is up to 10.000 farads? 300 times less energy storage. And don't counting the charge recovery which the chemistry can do. Also 2.7v vs 12v, so you needs to place like 5 capacitors in serie, which the result is like the half of the half of the half of the half, 5 times half! Because the formula would be TOTAL CAPACITY = (c1 * c2) / (c1+c2) = cr1 ; (cr1 * c3) / (cr1+c3) = cr2 ....
