We've been putting caps on race drones for years (to level out the stress we put on batteries through constant changes in acceleration, and have a smoother video signal), was honestly disappointed to learn my M3 did not have one :(

I've been trying to get this type of hybrid synergy going for years, I also think the graphene tech will play a huge role as well as ongoing improvement in the lithium theater. One day it might just prove Goodenough...😂

The Future looks good with the Evolution of Battery Storage and Renewable Energy. Let's just hope Big Oil embraces Green Energy!!!

Pretty good video. But more information on (super)capacitor historic energy density trend and cost reduction over time would've been nice. (Weren't there a few laws named after people about that?) Also there is the supercapacitor based on soft contact lens material with an energy density rivaling that of early 2018 batteries: Alternative to traditional batteries moves a step closer to reality after exciting progress in supercapacitor technology by University of Surrey phys.org/news/2018-02-alternative-traditional-batteries-closer-reality.html Superdielectrics Ltd www.superdielectrics.com/ The video also neglected to mention the self-discharge of supercapacitors being a problem for replacing batteries. And another thing; development of 2D-materials (insulators, semiconductors and conductors for computer chips) might lead to very high energy dense supercapacitors. Also some companies compare their supercapacitor tech to lead-acid batteries. Lead-acid batteries are what the companies are trying to replace (thus it's a fair comparison) but lead-acid batteries have a lower energy density than lithium-ion batteries.

I've always considered batteries the achilles heel of EV transportation, if not the archaic electric power grid. I think supercapacitors just might make EV transportation technologies viable. Currently, they rely on subsidies and a lot of market interference. Battery technology won't go away, but I think supercapacitors will "take the load" off battery technology (pardon the pun) in the EV market. I wouldn't be shocked if they find a big role in mobile computing and even foster new technologies.

I thought I was the only one to notice. . .

@@hammerheadcorvette4 ,

He seems to do that a lot... I find it amusing.

Interesting comparison.

And this is exactly how I transitioned, my pc is full SSD now :) the next upgrades will be NVMe

The thing is SDD is better in any possible way but price that’s why they used a combination of both (to save costs). Now that SSD has become affordable enough, there is no point in using a worse technology. However, super capacitors are not better in every possible way than li-ion batteries. Therefore, it would require them to get improved to be a better alternative to li-ion batteries. However, capacitors are an ‘old’ technology and hasn’t got ‘much’ room for improvement whereas lithium is only taking off and it’s seeing improvements every year. This makes supercapacitors only suitable for certain applications. Here is a video about it, it was very interesting you make like it and learn some things: ukposts.info/have/v-deo/ZWeFYWyPm5-Dtas.html

What missing in the comparison is specific energy, or size of storage. If SSD's were huge you wouldn't be able to transition to pure SSD.

Hugo de Andrés for now it is, but not in the beginning. In the beginning it failed a lot, was very small and it was very expensive. Over time it improved a lot and the price wend down. It the same amount of R&D that went into SSD over the last years went into Supercaps i wonder how much it would improve.

Hold on let me check Edit: holy shit your right

@Alex Gibbs Nintendo's batteries tend to last really long times. I for one have 2 Gameboy Advance SP handhelds (the backlit ones that close lile the DS) which I purchased in 2004 and took one of em with me all the time and to this day they still hold 2 to 3 hours playtime.

Thanks for watching!

The battery technology is never good enough for Goodenought!

its been the same forever almost like someone doesn't want them developing them to keep selling them.

@@dru4670 We talking about GM selling battery tech to Big Oil? lol...

I've actually been looking into them recently ... still have a lot more digging to do.

Lovesupee some people already replaced Thor 12 car battery with a SuperCamp set like you said, in EV's it might be used as a hybrida for charging but wait there, ia more

that sounds like a job for a regular capacitor ...

I use the same for my car. This one: www.norauto.pt/p/booster-norauto-premium-sem-bateria-mf450-2054033.html?CatalogID=48599&CatalogCategoryName=48702 It charges with residual energy from a car battery (or using a 12v socket, or even by simply charging at home), which has nowhere near enough juice to start the car, but its plenty to charge the booster, and after a few short minutes, it can "spit out" 450 amps. It doesn't completely negates the need of having a set of booster cables and the help of another car if the battery is at zero, but since that scenario is unlikely, that supercap booster makes me less reliant on needing the help of others.

@@00Resev really interesting man

Ah, but in that case, why charge the battery at all? You could be using the cap directly instead for higher efficiency. Only reason to charge the battery there would be if you're going to stop at another charging station before the cap is drained.

I pedal up to about 45kmh and then i just let the motor take it from there up to 80kmh since i can't pedal that fast.

@@numbdigger9552 those are rookie numbers. Gotta push those numbers up!

Very interesting, 10,000 cycles from full to fully discharged? Does that imply that the original capacity remains also? I bet it doesn't but I would love to be wrong.

@@conmcgrath7502 I had to dig into the warranty a bit to answer your question. I learned that my claim was incorrect. It's not 10,000+ cycles at 100% depth of discharge but 10,000+ cycles at an 80% DOD. And the warranty declares the batteries "dead" if capacity drops to 60% of initial rating. So not as good as I had assumed, but as long as I don't drop below 20% (often) I should get well over 20 years service and for the last 20+ years I should have at least 61% of my original capacity. The nice thing about lithium batteries is that you can add a new cell to an older group and the old cells won't pull down the performance of the new cell. That's a problem with lead acid cells. So I might need a storage boost in 15-20 years so I can just add a third battery and be back where I started. What might that mean for an EV? Suppose you had an EV with a 250 mile range. You'd want to avoid dropping below 50 miles in normal driving. If you take only a few long trips per year you might be willing to take the charge closer to 0% and cut a little life off the long end. And toward the end of life for the batteries your range would have (maximally) drop from 250 miles to 150 mile. Not great but still fine for normal daily use. Not many of us expect to take long trips with 20 - 25 year old cars. But now! Since I posted that there's new data coming out of Jeff Dahn's battery lab. Dahn is Tesla's battery guru. His lab has been testing some lithium batteries continuously for three years. Charging and discharging day in and day out. So far they've managed 15,000 cycles so this isn't the final performance data. It's what they've found so far. The cells they are testing are divided into four groups. One group does full 100% discharges, one group does 75% discharges, a 50% discharge group, and a 25% discharge group. After 15,000 cycles the 25% and 50% discharge groups have lost no capacity. If you had a 250 mile range EV with these batteries and you almost always recharge before the range dropped below 125 miles you'd have as much range after 41 years of daily driving as you had when new. And that range might hold for decades more, we just don't know how long yet. The 75% and 100% discharge groups (250 mile range, drive to 'empty') and you'd lose 13% of the range by 41 years. From 250 miles to 218 miles for your 40 year old car. It looks like we will soon have EV batteries that last far longer than most cars. Will we buy new bodies and move our still good batteries into the new body? Or will we sell our batteries to companies that do grid storage? And, further. What will this mean for incorporating wind and solar on our grids. Tesla has figured out how to drop the cost of battery cells by over 50%, largely with new manufacturing techniques. So a much cheaper battery with incredible lifespans. Take the old cost for storing electricity in batteries. Cut it in half. Then cut it again by a much larger number due to batteries that will last decades. We need to see these batteries installed and operation in the real world but if the lab results to the real world then we're about to see a massive shift in how we generate electricity.

@@bobwallace9753 Thank you Bob for taking the time, quite the reply! I am still a skeptic, it's not that I don't believe you (and you seem better informed and more 'current' in your knowledge than I) but the various manufacturers have a way of presenting the most positive results in the most favorable way? For example, do the discharge tests reflect the power demands of the cells in a real world environment? Speaking of environment, how do they perform when it's sub-zero all night? Do the battery banks suffer from vibration over an extended time? Ref your own words regarding the warranty, another interpretation might be '10,000 cycles' if you never discharge below 80% and all bets are off if you dare to discharge below 60%? . I'm not trying to be a 'dick-head' here (my friends will tell you, I don't have to try) but the figures seem extraordinarily optimistic. As I said previously, I would love to be wrong and I have to admit, after a career that primarily involved lead-acid battery banks as a power source/resource maybe my opinion is prejudiced. Here is another 'angle'; a fossil-fuel car might run out of fuel, but if you beg, steal or borrow a gallon, it will get you to the next gas station. If your fossil fuel car has a flat battery. then a 'jump-start' will get you going again, not the same for electric vehicles, run out of power? Shit out of luck, you have to be towed. Bad storm, no electricity, don't depend on that vehicle. I'm not 'knocking it', I believe the future will demand electric vehicles but I would be very surprised if any Emergency Response Vehicles are made electric only in the foreseeable future, for good reasons. I have one thought to offer, all electric vehicles should have a solar panel on the roof, not so much to make them more efficient, but if you do run out of power, at least after a few days (not covered in snow) the batteries should have enough charge to run a few miles and maybe get you home. Cheers matey, I'd love to know how you get on with the new 'set-up' as I am considering an 'off grid' system myself and haven't ruled out pneumatic storage yet, but that would introduce a whole lot of engineering and couplings which are subject to failure, moisture and noise.......battery banks are quiet! Thanks again for the reply, I have a few things to think about. Pax dude.

@@conmcgrath7502 The Jeff Dahn data is from a research scientist. If that's how you earn your living you really don't want to intentionally mislead. People get drummed out of the business for dishonesty. That is not to say that mistakes aren't made, but that the motivation is to be truthful. Not to tell stories to aide the business. I haven't read his paper, I'm not sure that he's published his results yet. The data was from a presentation he made. IIRC the batteries were tested in the sort of way that they would be used in cars. As far as I know batteries are not impacted by vibration. Cells are basically tightly packed paste (most cylindrical cells) or tightly packed dry powder (Tesla's new dry roll cells). There's nowhere for stuff to move around inside the can. I don't think cells are harmed by cold. They just don't produce as much power when cold. Heat them up and they perform as if it's a warm day. If you live in a really cold place you'd want to keep your car plugged in at night and pre-warm the cabin and battery pack before taking off for the day. In super cold places there are often curbside outlets where ICEV drivers plug in their block heaters so their oil is viscous enough to allow their car to start at the end of the day. I didn't do a good job with the discharge limits on the batteries I'm using. Stay above 20% charged, not above 80%. 80% of the battery charge is usable. My previous batteries were Trojan RE batteries that had really thick plates. They were rated for 4,000 cycles if you discharged no more than 20% or 1,000 cycles if you discharged down to 50%. Very different from these LiFePo batteries I've got now. Running out of charge? Just don't. Go to Tesla's Supercharger page and look at how many rapid charger stations they have already built. At this point I don't think there is anywhere in the US where you can get more than 200 miles from a Supercharger. And their goal is to have Supercharger stations no further apart than 35 miles along most travel routes. Tesla EVs are really sell set up to warn drivers that they need to stop for a charge well before it's time. I guess some people will ignore the warnings and have to call for a rescue truck, but that's just who some people are. AAA has some EV rescue trucks but I don't know if they get any use. IIRC they have large battery packs onboard and can give an out of charge EV a few miles of charge to get them to the next charger. I'm not seeing running out of charge as something that we need to worry about. Cars are so smart that we could set the headrest to deliver a dope slap if the driver ignores the flashing light to stop at the next charger. And I think insurance should not cover running out of charge. Let the driver pay a bunch of bucks to be hauled to the nearest charger on a flatbed if that's what it takes to get them to pay attention. As for offgrid, I've been off it since 1986. It's not something that I'd recommend to someone who is hooked to the grid. Install solar panels, perhaps some batteries, but let the grid be the "deep storage". But I bought land that was well off the grid. The utility company wanted $300,000 to hook me up. That meant that I was able to buy a very nice piece of land at an affordable price. Few people knew about solar and the lack of grid power kept the land price very low. When I set up my previous system 20 years ago (I had another off the grid place earlier) solar panels were expensive at $8/watt. I didn't install enough to carry me through periods of cloudy weather. I've now installed a new set of panels with 2x the wattage and switched to a maximum power point tracking charger so I'm hoping that I don't have to use my generator during extended cloudy periods. Or at least not much.

Glad you enjoyed it!

I hope John Goodenough lives long enough to complete his work we are almost there!

Indeed.

I have no idea what those words mean

Maybe, but the question is whether adding super capacitors (or any other tech) to EV's is good enough from an economic standpoint not an engineering standpoint. Nobody is arguing that they would not add any value, the question is whether the value added is worth the extra manufacturing costs. And whether there is another added value that makes more sense to pursue first. Like Elon says, manufacturing is difficult and "good enough" is relative.

It comes down to a cost-benefit analysis. What will be the expense, weight and usable vehicle interior volume penalties, as well as the design changes required, and are they worth the advantages?

Tesla and similarly wired batteries can easily source enough current as they are. They don't get much benefit from supercaps, as it's the charging cycles that stress these batteries - not the inrush-currents that would stress smaller batteries. The larger the battery pack in terms of capacity and current throughput, the less supercaps help with longevity. Also supercaps have low voltages, generally 2.7V, so you'd need a series of 140 to barely be able to operate, much more to do that safely. The volume and weight this would bring would defeat the purpose.

@@alexoja2918 With capacitors in series, the energy storage in kWh adds up as you'd expect. Energy is proportional to voltage squared, and since voltage adds up with capacitors in series, the capacitance must drop or else you'd be getting exponentially increasing energy density.

@@dekutree64 Totally correct, i wasn't thinking about power as i should've, but capacitance alone. I've removed the mistake, thanks for pointing it out.

Thank you!

@Mattew Connor What gives the long range to heavy trucks is to have the ability to go 600 miles between fueling or recharging. Batteries as they are now can't do it in a cost effective way. Hydrogen fuel cells can do it.

@@acmefixer1 I was more focused on delivery vehicles that do a lot of stop and go but don't cover a lot of miles in a day. That's were using a super capacitor could offer real benefits. Highway driving it's more about aerodynamics and energy density.

Acme, I think they were talking about super capacitors being used for regen.

I was thinking the same thing, but couldn't get the words to come out right. I can only imagine how much more distance you could get from your Li battery?

@@aussie2uGA It hasn't changed ! 'supercapacitors' may be great at 3 volts but can't handle the 400 volts or more of an EV motor and are therefore an irrelevance.

pasoundman You can series connect them to get whatever voltage you want. There are also capacitors that are much greater than 3v

Maybe I will be able to share some details later this year 😉

They really are.

capacitors are SIGNIFICANTLY cheaper and lighter

@@-LightningRod- I think batteries are cheaper and lighter and also less volume.

@Allen Loser uhhhh, yeah thats a capacitor used as a battery, they are not batteries, typically a capacitor is a foil with andie-electric coating and hollow.

@Allen Loser yes i believe it is ideally suited for the regen cycle

@Allen Loser uhm capacitors are VERY light, ... typically

So is the flame of a battery

Try shorting one out, a nice effect too.

Would they be dangerous paired with a battery in a vehicle? Risk of explosion/fire etc?

@@BrettHoustonTube Yep it'd be dangerous. A capacitor works differently than a storage battery. A storage battery, lead-acid, lithium, or whatever works by using a chemical reaction. A capacitor is just a sheet of conductive material (a sheet giving the most surface area for a given mass) that stores electrical charge on it's surface. The problem is to make the capacitor so that it may be charged up and then discharged without accidentally grounding it out.

I hope so, but people have to think out of the box to overcome the physical limitation. I am working on it, I hope I can make it!!

They never will, unless battery technology completely stalls, but they don't have to in order to be very useful.

I look forward to the day when all capacitors have equality and freedom, batteries shall no longer dominate the storage media and even tantalums can have their say! (sorry mate, couldn't resist) Pax dude

@@conmcgrath7502 Nicely said... Capacitors are designed for storage and cannot make power. Batteries are designed to make power and incidentally have the ability to store a charge. The big problem with most batteries is that they destroy themselves over time and create some nasty waste as a result.

I think SSB and Supercapacitors would be a great deal in the future (10-15 years)

Solid state is much closer than that. Several variations have been licensed for over a year. Usually that means market within a year at some price, usually high, but than down.

I do exactly that with my muscle car with high cranking current. It killed an expensive Optima ‘Red Top’ so I have a ~90Farad super cap unit from eBay (suitably wrapped in heat shrink) protecting the replacement battery for those critical couple of hundred milliseconds after I hit the starter. So far so good for the last 4 years.
