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.

It’s simple: just store the energy in my Nintendo DS. The charge will stay 100% for millennia.

I'm a big fan of super caps and i really hope that some day they could reach just half the power density of li-ion batteries. I think a car that has half the range but you can charge in seconds or minutes would completely revolutionize the industry. No more range anxiety.

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.

As always an excellent video, thank you. It makes so much sense to use these. It's like computer cpu cache memory. Small but very fast and in combination with slower memory/disc the whole system performs drastically better. Plus I suspect as it is not a chemical process it will not be affected by temperature much. So EV Regen in the winter would work as well as the summer. Thus improving winter driving range.

thank you for making the distinction between specific energy and energy density. a lot of people try to use them interchangeably. Thank you for the video in general. I still believe supercaps will replace redox batteries. Hybridizing them is the first step. There will be some interstitial or other modification to improve energy density. The difficulty i see is supplying power at linear discharge rates. High frequency switching (IGBTs) in parallel to a load to keep the load supplied at a constant rate is a viable path i see.

Great for off grid storage systems as well. When used with a lithium battery bank they will cover the spike loads from the inverter (ac, microwave,nwashing machine. They also help draw a bit more power from PV systems by having less resistance. They will accept a charge at a lower current especially in the morning when the charge current is low.

I use a supercapacitor jump-pack to jumpstart boats. They're neat. Half the size and weight of the old style that had a motorcycle size battery in it, but it'll turn over a big diesel engine. Once. The upside is that you put it on the good battery and it charges back to full in a minute. That's really what they're good for putting out really high amps for a short time. They're never going to replace batteries. What they're good for is spike loads. It doesn't matter if they can only put out the power for two seconds if you're using it to go 0-60 in a Tesla.

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.

Excellent summary Matt. Very pleased you got around to it. I see a large market for hazard-free supercaps in IOT devices also, hand-held scanners, meters, sensors, and wearables, supporting lithium-ion batteries, since these batteries have an environmental concern due to lithium toxicity/mining and recycling. Not only this, but as you mention lengthening the life of lithium batteries, it enables the product user to reduce costs in maintaining their devices.

Really good info, thanks! Always wondered how the issue of charging a battery as quickly as filling a gas tank could be solved, looks like supercaps are it. Quickly charge the capacitor at a charging station, then let it charge the battery while you drive.

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.

Just some info on battery life. I recently replaced my worn out lead acid batteries in my home solar system with lithium iron phosphate batteries. They are rated at 10,000+ full 100% to 0% charge cycles. With a daily full cycle those batteries should last over 27 years. BYD, the Chinese battery and EV manufacturer, has been using lithium iron phosphate batteries in their EVs. The batteries are heavier than lithium ion batteries but apparently Chinese drivers are not a concerned about long ranges. Tesla is now using similar batteries in the Model 3s they are building in Shanghai. 200 mile range. 10,000 cycles. That's two million mile battery.

@conmcgrath7502

@bobwallace9753

3 жыл бұрын

@@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.

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.

I could see supercapacitors finding a place in the drive train comparable to RAM in computers. In heavy vehicles like delivery trucks/vans, this could significantly help their range and longevity.

Great video, (as in confirms my thinking)! Why do Tesla and others not give their hard working batteries a supercap armchair to relax into. With the right arrangements of supercaps and control programming, the stresses of high power demand alternating with high regeneration could be evened out, the supercaps taking the strain. Million mile battery right now, with an easy life like that, and no loss of performance.

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.

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

The best part of super capacitors is when they fail . All the energy stored is released in several milliseconds and the resulting flash and bang is spectacular.

@aceroadholder2185

@@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 believe the swiss also pioneered the gyro driven buss. Amazing design would run 4-6 hrs on a single spin up. A great feature of gyro driven vehicles is when heading downhill it adds energy directly into rotary motion of the gyro. Be interesting to see what they could do with an electric motor that draws power from buss stops to add energy to the gyro.

Thank you Matt. As always, you have given me a much better understanding of the subject matter.

The one aspect you're missing in terms your question wheter or not we will see supercapacitors, is the economic feasability. If it's not economically worth it, it won't happend, if it is or will be, it will happend.

Very informative video!

That swiss bus thing is super cool. You can grab enough charge when stopped and then let it bleed to lion battery while driving. That opens the door to car that you don't ever need to charge but charging system is in the road itself. 250 against 25 energy density already gives that possibility. And the carbon charger supercapacitor can be used to add structure to the car body too.

How will solid state batteries affect all this, when and if it becomes available.

Matt Excellent information Thank you for sharing

"I'm Matt Ferrell..." That sounds exactly like something Billy Corgan would say if he's masquerading as a scientific youtuber.

Super-capacitor technology has some great pros, however it is far from being mature and ready for industrial application. Energy density needs to improve by 20x for SC and 2x Lithium-based -at least. Matt, you didn't talk about price ($/Kwh), but I expect it is quite high. Hybrid batteries could work at the beginning, but I don't except to see any mainstream car in the next 10+ years.

I love them, no internal resistance so little loss on charge or discharge. I think you identified the possible best use for recovering energy to accelerate rather than stress the battery.

7:49 This article is more than TWO years old! I would expect that after a "breakthrough" 2 years would be enough for some monetization or at least an update about it, Matt. You must have missed the date of the article. Great video; thanks for all the good information!

Great episode!

Combining super capacitors with your 12v car battery can make starting it easier, especially in cold weather. You use super capacitors as a battery replacement but you still keep a standard car battery in case the super caps go dead from.. listening to the radio with the car off for example. Since you won't get much time due to the very low capacity. The (cold) cranking amps of super caps just make starting the car so much easier. I actually considered putting super caps in my old car before i sold it, since it had a sunroof that could have fit a solar panel that would have kept the caps topped off from the passive battery drain from the radio's clock etc.

intersting video! i was wondering actually will different battery sources have any impact on this? i was ready that polymetallic nodules could have higher percentages of minerals and does that also mean better quality for energy storage? i was more excited by how much less environmental damage collecting them does!

Great addition to a marine battery bank it does the grunt work when high start currents are drawn, engine starts is a good example, but also increasing demand for inverter s suppluying
