I admire your enthusiasm. And enjoyed the mountain of top notch research you presented. I'd like to see hybrid battery- super/ultra capacitor banks become a thing.
Hi Archit, thank you for the excellent and clear explanations. You have a great narrative voice and wonderful grasp on physics, electronics and more. Subscribed, hope to hear more from you. Thanks!
First, I salute you, second, I ask you pls make more vids, and third, could you please give an example on how you would make a battery bank work with super capacitors? Let's say I want to build a 96 volts system to give a 96volts electric motor propulsion to assist my gas car. Should I then build a 96volt battery bank and also at 96volts super capacitor system in parallel? Or a 48volt battery bank and a 48volt supercapacitor syst in series? (Assuming the controller can take from 48volts minimum to 96volts max)
It seems to me the closer you can get the positive and negative plates together the greater the storage capacity. But also the insulator would have to be thinner and not leak or short circuit. So we need a super insulator.
If u increase the distance of the electrodes from the seperator, the power density which supercaps are good at decreses. Next gen super caps are already here , that surpass lithium ion
at 1:20, energy density is confounded with power density. most people think energy and power are the same thing but power is the time derivative of energy. thats the who point of this video and the main difference between super caps and batteries. whats interesting are hybrid lithium caps. might be the worst of both worlds though we will have to see. too expensive for now
Sad that you don't have any more videos.. You seem really enthusiastic about these things, try experimenting! I'd love to see what supercapacitors can do on RC vehicles. I myself am reluctant to put them on my drone since it doesn't have any space left and I don't really know how to properly connect it with a battery
Yes I am working on my own RC car with this type of hybrid battery system that I can recharge very quickly and get some launch control as seen in cars using the super caps high energy discharge capability. It has some other sick features I am working on so that's something I am pumped about. In that video I can explain how we can connect them together so stay tuned for that, it should probably help you!
They have a low energy density which is why they are not used plus they are expensive which is also why electric automakers don't use them I would love to do a video explaining the different type of batteries that are coming up like some bio batteries and other such batteries if anyone would love to see that just like this comment/reply and I can make that happen.
@@architsakriyes, plz make one video about the different types. But do you know that i don´t mean LTO batteries, i mean NANO LTO batteries. They aren´t on the market already.
Also you said the time it takes for electrons to cross the separator increases if you increase the storage capacity. Electrons do not cross the separator plates. They go around the ends.
Well in that argument even I agree. People think they can replace batteries with supercapacitors. They would be very complementary in something like an electric super car. With the Supercapacitors high charge and discharge rate we can give a very quick boost to the motor for something like launch control seen in a lot of fast cars. So whatever batteries cannot do in some aspects, supercapacitors will achieve that goal. So in retrospect they obviously cannot replace batteries, but they are very complementary to them. But I am going to make a video of it proving this and actually be making a hybrid battery that uses both supercapacitors and batteries.
Also the charge and discharge time in a capacitor is so much shorter than a battery. Increasing that time, the capacitor would still be thousands of times faster than a battery. So your argument is not logical in regards to a capacitor being used as a battery.
I never said they can be used as a battery. I said they are complementary machines that can benefit each other in particular aspects. So it really depends on what you are building or for what use case we are talking about. For a solar panel array you could use supercapacitors depending on how big your solar panels are. So for something like a car a hybrid battery system would be very beneficial in which both supercapacitors and batteries are working together.
@@architsakri Capacitors can replace a car battery quite nicely. But you are correct, a hybrid design of capacitors and batteries will be the winning design.
The discharge rate of supercapacitors is higher than lithium-ion batteries. So, the self-discharge rate won't allow you to store energy for a long-time. When batteries supply a constant voltage, the voltage output of capacitors denies linear charge systems. However, supercapacitors are suitable to use for solar panels. But this argument is only applicable to a device such as a solar panel. This also depends on how big the solar panel is and how many super capacitors you use.
