Maybe the next generation, or possibly something in the family, but I don't think it will replace batteries, definitely not likely for everything, maybe small current loads, remote control equipment, clocks, maybe some electronics, I don't think we will be running homes or cars off them!
I have always had the feeling, maybe a dream if a battery that is cycled then the electrolyte, or electrode is replaced. Then it's like new again. Or maybe this is how it's charged, possibly a insane amp hour cell, that can be charged a few hundred times, the the electrolyte is changed, then it's new again, it would be awesome to drive a car 25, 000 miles the a electrolyte swap, then another 25k miles, but I did say 'dream'
Maybe someday we can have batteries that work similar to caps, and LTO batteries as far as cycles, but charge effiecnt and fast, capable of 100-500+c to 80% charge rate, atleast, have a 2kv DC charger, at 30-40 maybe 50-60amps that's a ton of watts! Equaling a fast charge, I think a universal smaller battery pack that can be swapped out would be a great idea, giving 50-80 miles of so. Range. It could be used to charge the main battery, while driving, when charging isn't a option, or as a range extender,

These things seem really interesting at twenty cents, rather than 20 dollars. I am sure there will be some applications. But there will be a lot more applications as manufacturing scales up and costs come down. 0. 25 Wh is just not a lot of power, and it isn't very volumetrically dense so it isn't suited to super mobile applications. It's a very narrow niche where the advantages win out against other options right now.
That said, I love the idea of some permanent devices that aren't limited by charge/discharge cycles of liion batteries. Super caps may be a piece of the puzzle for having some electronics that are less disposable, and that seems like a good thing.

I replaced the battery on my quad with super capacitors. Was sick of having to maintain batteries on something that was not used that often. I pull start or boost it if I had not used it in a few days but the capacitors take the charge fast and I can use the electric start and lighting on the quad. I was surprised that with a full charge I can run the led headlight for at least an hour as task lighting without having to run the engine.

Hey Scott! Here s an idea inspired by your electric car comments: what if supercaps and the batteries worked together in a circuit where you could deliver a super high current to charge a cap bank quickly, unplug and then let the capacitors drain slowly to charge a battery.
Although maybe a cap bank with the same capacity as a battery would be meaningless, I don t know enough, but I d be very interested in learning more.

Thank you for the video.
I'm designing an hold-up PSU, an auxiliary power supply which is meant to hold-up the voltage of the main power rail when the external power supply is suddenly removed so to allow the system to gracefully shut down.
Commercially available supercaps are also rated at voltages higher than 2. 7V (5V or 9V for example) and I'm wondering why you haven't included those in your comparison.

I think supercaps can be combined with lithium batteries to make a hybrid battery. Say one side is supercap and other is li batt and a soft wall in b/w to separate them (imagine a smartphone battery like this. They can then be linked to each other using appropriate circuitry (and ribbon wires in embedded case. This way we can have all kinds of advantages.

The issue with supercapacitors is their voltage is proportional to the charge level (2V 100%, 1V 50%) batteries can retain a mostly constant operating voltage up to the point where there almost discharged. So using a super capacitor currently would require a boost converter to maintain a constant voltage on whatever load you re powering it with.

You should look into Headway Lifepo4 batteries. The red version. Up to 200 Amp sustained continuous discharge rate! Very safe and a much longer duty cycle than Lithium Ion batteries.
4 Headway in series will make a wrench glow. 8 in series will literally melt a Craftsman wrench in half!

Great video, thanks! :)
I had the same idea as MC's Creations to order 4 of those for a spot welding project, but I got a heart attack when I saw the price: D I think high crank AGM lead acids are still the cheapest source of high current DC!

If you want the highest capacity you need the capacitors from Skeleton Ultra capacitors. Ultra capacitors are for example already used to store large amounts of energy in combination with wind turbines at an island in Scotland.
