Not the first time a promising technology dies in infancy, or doesn't even get out of the "womb". Back in the late 50s, and early 60s, the Esaki diode (aka tunnel diode) was going to revolutionize electronics, universally. But these damn things called ICs (integrated circuits), went and pissed on their birthday cake. Yes, tunnel diodes still found a use, but only in niche areas. Later, in the late 70s to early 1980s, bubble memory was going to be the big thing. But improved hard drives on the higher capacity side, and solid state non-volatile memories, such as EEROM (not EPROM) and Flash, killed it in small portable applications.

Imagine you have two types of very small, cute monsters: tiny ants and microscopic cats. Tiny Ants: These ants ooze out jumping beans. Microscopic Cats: These cats love to eat jumping beans. Think of a battery as a container split into two halves. One half is filled with these tiny ant monsters (the anode), and the other half is filled with the microscopic cat monsters (the cathode). When there's a path for the jumping beans (electrons) to move from the ant side to the cat side, they will naturally want to flow to the hungry cats. This movement of jumping beans from ants to cats can be harnessed to do work, like turning a mill or turbine. Similarly, in a battery, the movement of electrons from the anode to the cathode through an external circuit powers electronic devices. So, in summary: Ants (Anode) release Jumping Beans (Electrons). Cats (Cathode) eat the Jumping Beans. The movement of these jumping beans can be used to power things, just like the flow of electrons powers electronic devices

Unfortunately, by then it was too late and everyone kept using conventional theory. They also didnt want to admit their mistake and the conventional theory carried on where most technicians use conventional flow and engineers use electron flow. Its confusing as hell but thats the story.

My French 10 years car... is 79000km... and the 89cv engine is like a new.

This is an interesting development and I hope the information the company has provided is accurate, but a couple of points: 1. Another benefit of a solid state electrolyte is that it won't be flammable and almost impossible to put out in case of fire, and that issue remains in the discussed battery even if it should be very stable under standard conditions. 2. If the metals used are still the same rare ones with their large environmental impact, unless they could use this technique to speed up the development of the more appealing alternatives that currently underperform this will also remain an issue. 3. Regarding energy density for large planes as is suggested in the video - jet fuel has an energy density of about 12,000 Wh/kg, so it's still around 24 times as energy dense by mass. Even though theoretical jumbo electric planes would use a completely different type of engine, let's still put it in this perspective: a Boeing 747 is quoted as burning 10 to 11 tons of jet fuel per hour of flight, so a flight from London to NYC at around 8 hours burns more than 80 tons of jet fuel. The plane would not be able to fly using ~2,000 tons of batteries, as that is 12 times as heavy as the empty plane is. Even for much shorter flights I don't see how it is viable in planes built to carry hundreds of passengers, because even if the flight is short enough to require energy that can technically be carried by the engines, maximizing the weight at every short-haul would make short flights _much_ more energy intensive than they ideally should be.

It is true that in that case, the cathode is the negative terminal. Unfortunately, chemistry had another definition. They defined the cathode as the electrode where reduction was taking place, and the anode as the one where oxidation was occurring. That meant that strictly speaking, the anode and cathode of a rechargeable cell swap places when charging vs discharging. It’s a total mess. This is why several scientists have proposed dropping the whole anode/cathode thing altogether. They suggest names such as positrode and negatrode instead, where the polarity defines them rather than the oxidation or reduction. Personally, I think it is an excellent idea.

So the Apter could have a 2000 mile range with this?? Sign me up!

Excellent video! However, the first battery diagram has an error. The cathode is negative inside the battery, but positive on top. The reverse is true for the anode. Inside the battery, the cathode is negative, and electrons leave it to neutralize Li+ ions flowing to it, so electrons are pulled down into the outside cathode terminal.

When you look into this at a deeper level you realize because it's not better in any meaningful way from what currently exists. Because of it was other people also working on it have also likely stumbled upon it, did some rudimentary tests and dismissed it as too expensive, too impractical, or too dangerous vs what you can currently buy. Nobody is going to buy a battery 3x more expensive that delivers 20% more capacity/life. Of course some might, but you could also just buy a 20% bigger battery in the first place. Don't get me wrong various material and dimension tweaking has enabled super fast charging, higher capacity, and lower degradation. But it's more like going from 1x to maybe 1.3-1.5x in 20 years of progress. We're not going from 1.3x to 50x. That ain't happening like it did in the electronics world. It's theoretically possible to hit maybe 7-9x but we don't know how to make those batteries last more than 1 charge if we can get them charged in the first place without falling apart. When that problem is solved (if it can be solved) you'll see week long battery life phones and actually viable EVs happen over night.

10/10 video. Thank you!

Nice video, but as an electrical engineer, I feel I should point out a couple of minor mistakes. At 2:11 you show a battery consisting of, anode, cathode, and electrolyte -- which is fine -- but you show it connected to another battery, like when jump-starting a car. I think you meant to show the battery in normal operation, so it should've been connected to a load, not another battery. Also, you got the flow of electrons backwards. The negatively charged electrons are attracted to the positive anode, so they come out of the cathode, go through the load, then return to the anode. Conventional current flow is in the opposite direction, from plus to minus.

“We won’t get into the other components”. Fail! I have no doubt that if it does work as stated, this will increase energy density a bit. BUT: The main weight in a cell is the cathode. Lithium metal anodes only improve the weight of the anode. They do nothing to the cathode. Also, this new structured gel electrolyte will be heavier than current gelled/polymer electrolytes, and I seriously doubt if it can maintain its structural stability over thousands of charge cycles - side products will inevitably build up and degrade its delicately balanced structure over time. Also, the energy density is nowhere near that required for aircraft. Maybe a city taxi service would work, but that’s it. Just read up on international aircraft regulations regarding emergency fuel loads for long haul flights - we’re still a factor of 10 or more away from making that happen. Ask those PHDs you ‘interviewed’ about these issues, and if they disagree, check where they’re being sponsored from! Lastly, CATL has spent enormous amounts on expansion in recent years, and faces an uncertain future in China due to lacklustre domestic sales, reducing CCP support and flagging volume sales internationally. They’re in a bit of a tight spot. I wonder if this is a ploy to generate investment? After all, they haven’t demonstrated any of this yet - just white paper hype so far. I remain highly suspicious.

While CATL is a well know and reputable company, this is a huge jump in battery tech. There have been countless “industry disrupting breakthroughs” from all sorts of companies, only for them to not be commercially viable. So I’m with you on being skeptical. I’ll believe when “Great Scott” has a cell in his hands.

If we can't fight the dendrites, we can control their growth. It is necessary to create a closed road for each dendrite. When the dendrite grows to another wall, it closes an electrical contact and the electric current through it is turned off. And the electric current begins to flow through another dendrite along another road.

Thank you

So interesting - great to see a battery technology that feels feasible for the future!

I thought that solid state batteries were supposed to be safer than traditional liquid electrolyte batteries. The liquid electrolyte is very inflammable which results in fires if the cell short circuits.

With CATL's reputation to deliver what it is promoting and a review from an independent source it gives me confidence that CATL condensed battery at around twice the current energy mass density is a real possibility for the aviation market. The aviation market could have costs ten times what would be viable for the automotive market. It would certainly replace any large batteries used in aviation currently. If all the other criteria for the CATL condensed battery are as good as LFP batteries with more cold tolerant chemistry they would allow a near doubling of BEV range which would make long haul semi travel BEVs viable and able to economically be driven faster than Diesel.

Especially in the US who keeps finding huge deposits. We have the single largest deposit of lithium in Mount McDermett or whatever. To produce the lithium needed for a 64 kWh battery pack, for example, Fichtner stated that about 3840 liters of water are evaporated according to usual calculation methods.

That said, annually 23T gallons of seawater goes into desalination plants and leave behind about 14T gallons of brine. Within that brine is about 17000 tons of lithium. If 20-50% of that lithium could be recovered, that is enough to make 400k to 1M 55kWh EV battery packs. So, just from mining the waste we already creating while making drinking water from sea water we can take a decent sized bite out of lithium needs. And I think the expectation is that the amount of water we get from desalination plants is likely going to rise in the future, so that should scale a bit with rising lithium demand. But, maybe you'd say that 5-8k tons of lithium per year isn't anywhere near as much as we need... well, there are already plans to mine the existing ecological disaster, the Salton Sea, which is expected to have about 2.5 million tons deemed recoverable. Enough to make several hundred million 55 kWh batteries. And when the batteries are no longer useful in cars... they are still useful for fixed storage. When they are no longer useful for that, near 100% of the lithium in the pack can be recovered and go into brand new packs.

Hi Ryan @ZirothTech, great job on this very exciting development in battery tech. Just one note from someone covering flight applications. I think an important distinction to make about all the references to the ton-scale aircraft test was that it was, in all likelihood, in non-motive roles. In other words, it was tested for systems other than propulsion. It could be avionics, cabin lights, whatever. But it was not to move the aircraft based on what you disclose and my own reading of the CATL website and other sources. To be very clear: These non-motive systems are still very weight sensitive and increasingly electrified so should this technology reach commercial, FAA-approved application, that is a big win. It would be an even bigger win if the above occurs with application as part of the propulsion system. Nothing I've said above precludes that. I just feel that the thumbnail and video content imply incorrectly that the testing and initial application are aimed at heavy aircraft propulsion and that is a very long way away. Candidates for early adoption in propulsion would be Urban Air Mobility (UAM) / Advanced Air Mobility (AAM), flight training (really ideal application), Light Sport Aircraft, etc. Hopefully regional airline and business turboprop-class aircraft would follow soon thereafter.

It would be like taking a present day coach that offers you a ride of 1500 km's or 1000 miles to your holiday destination. Many people use these coaches, they are the cheapest way of travel.

@@DekkerVinc I don't recall anyone here saying that. They are saying that testing was being done in an existing, licensed to fly aircraft, with known performance characteristics. Which provides a reliable way to measure results. Future aircraft designs, including those intended for low to zero emissions propulsion technologies are emerging all the time. The ALICE is mentioned above, and in my comment I outlined the various roles with potential, including regional airline travel. 🤷🏻‍♂

@@aerospacenews I am also thinking that ALICE may expand from its 8 passenger prototype to 16 passengers due to advances in battery tech by the time they reach certification. Thanks for your post.

My reading of various web articles is that the SHENZING plus battery has an energy density (albeit, at the pack level) of only 205 Wh/Kg, not the 500 you suggest.

Excellent

I always wondered if it would just be possible to use two lasers to remove dendrite formations, their focal point being just enough to degrade them so they never become a short circuit problem

Our battery is twice as strong as anything you’ve ever seen! Also you’re not allowed to see it, but take my word for it!

even if it makes it obsolete, everything can be still used. and might be easier to use or manufacture or some other factory. one of the points of solid batteries is that they are solid and not electrolytic like capacitors. ie no liquid related problems. lithium does not matter, it can be anything else.

Interesting idea, been reading reports from Sinonus (not involved) but they are making battery using carbon fibre as the negative and postive anode with a glass fiber separator so the strength of the unit and weight is so much better than any other design. Ok the Wh/kg for the time being is low but if the structure of unit, say plane is part to the battery then size of battery can be bigger with out costing weight as the battery itself is structural.

Fascinating, double the current best capacity surely will put an end to the worry about charging stations and so called 'range rage'

This is good, we need this tech ASAP! Especially with all the lithium fire we get. I hope this gets rolled out soon, but the cost of it still concerns me.

Hay COUZIN ~ Contemporary Chemistry has surpass the Ceramics Technology WE learnt in pottery🇨🇦

Liked and followed. Thanks.

I guess the highest Li battery should be Li metal.

Finally some real world, non lab only, non vapor ware progress. But it sounds like it will still take quite a while to trickle down to the average consumer. And unfortunately, we don't have very long as the earth's magnetic field strength continues to weaken at an ever faster and faster rate as time goes by.

They do make nice fires.

Ho-hum, just another revolutionary breakthrough in battery design. Wake me when one of these magical technologies hit the market....

Wake up and learn what is CATL then try to discredit them.

The plus marked part of the battery is where the electrons flow out from (excessive minus charged electrons) and the minus marked part of the battery is where the electrons flow to (positively charged ions). somehow that does not fit. 2:16 and from everything I learned the Cathode is positive and the Anode is negative. but the graphic at 2:16 shows it the other way around. Specially in the Electrolyte the plus charged Li ions flow in both directions, to cathode AND anode???

If batteries start to be square, it could be really cool

Even if you stop the dendrites, they build up a thick resistive layer on your anode and consume a lot of electrolyte because of their huge surface area. Honestly, I see way too many papers trying to physically block the dendrites and it's just not a good plan. You need to prevent them from forming at all, which is what I believe this cell-membrane thing does. It's like a "water"proof film that lets lithium ions pass but keeps out the electrolyte solvents so they don't react with the metal.

Hard to think of a thing to reaserch

6:48 skeptical, the "ball" type spheres will (like a filter) collect a lot of ions and show immediate charge time quick but slow down as they ions need to work around those. also it seems a lot of wasted space even though it appears high surface area. maybe the ions shoot through the space, I don't know. I'll wait for it to be "production ready" then see how it works over long periods, seems they are bragging for funding/investments.

I'm just going to wait for the next next innovation

start to watch video from 5:30 at least

Being on a bitter end of state oppression pushing for installing a lithium ore mine and refinement facility in one of the lush countrysides of Serbia, I am interested in supporting technologies which would obsolete the usage of Lithium altogether or at least reduce demand for it, such as Sodium-ion (), or even Hydrogen-ion batteries. Since this invention is mainly in domain of nano-geometric structures, I hope they would bring alternative chemistries into more close competition with Lithium, and beating it down with lower price for marginally lower (or why not even better) performance and much, much better availability.

Dendrites have NOT been the only focus of solid state. It's the main reason they haven't been adopted, but the solid state idea was to address the major undesirable shortcomings of Lion. Such as pollution in mining, charging time inversely proportional to battery life, intense fires that spread to everything around them and can flare up again weeks later, and as a result of that aforementioned fire hazard, entire cars being junked after accidents or 3-4 years of driving with nobody willing to purchase such vehicles. None of that even begins to touch on battery pricing. Or the insurance pricing. Or the fact that the infrastructure in the US simply won't deal with the power consumption required during peak charging times, regardless of the technology used. So, will CATL address these issues? Introduce new ones? The technology is amazing but like so many potential commercial attempts, will it end up being a great idea on paper? Perhaps limited to stationary backup power supply but not useful in EVs?

Well how about that. I learned something new at 2:05. I always thought electrons flow from negative (cathode) to positive (anode), although paradoxically we say current flows from positive to negative. Clearly I was wrong. (Or was I?)

As I understand, there is more to going solidstate than stability and density-- a reduced manufacturing footprint. Reducing cost and speed of manufacture.

As long as it's not in my smartphone I'll be crying

Ok, great! But how *SAFE* are these new batteries compared to the current lithium batteries? That would be the first thing I would like to know before boarding an aeroplane powered with them.

Ryan…loved the video. Do you have any videos on silicon anodes? There is a company in the USA that is far smaller than CATL. I haven’t written any research papers, like yourself, but from my understanding they already have a commercially viable, third party tested, 500 kWh battery. Amprius Technologies…have you heard of them?

New day, new game changer.

Solid state was vaporware... it couldn't even get out of lab... CATL is a true innovative company... Kudos for them....

Energy density just isn’t there. The best supercapacitors only store 10% of the energy of electrochemical batteries. They have their place, like in smoothing power delivery and absorbing spikes but as a primary store of energy, nah. Was never going to happen.

Sounds excellent! Why did we not invent that? We better get our act together!

We will completely solve the energy problem when large capacitors can hold their storage charge as long as batteries. I have seen things are looking up with some new developments in this area.

Solid state would need to begin before it can end. I'm sorry, but I'll believe a battery breakthrough when it's actually commercialized, in production, in products and affordable. I've been reading about these breakthroughs for literal decades, and none have made it to market in any meaningful way, if at all.

Rubbish. A lot of progress has been made up to production levels. Just compare battery specs now and 10 years ago. There is a very steep, continious, performance curve for commenrcially available batteries. No matter what you look at: Energy/mass or energy/$.

The technology is always improving and is always being upgraded, but it is not available to the general public for reasons known only to them. So it is not surprising that they have high-performance batteries that will be available only after 10 years 😅

Can you do a video about thorium reactors ? very promising, - especially with molten salt as a heat transfer medium

Great content energy density is the key has anyone bothered to work out the energy density of recycled renewable micro steamturbines and there ratio of energy density?

Very interesting. Wouldn't it be great if we could stop the dendrites from forming? What causes them to form? Does anyone know?

0:24 what is this keyboard o_O

Holy moly!

Lithium ion batteries have a larger problem long term. Even if we converted all known global lithium reserves and turned them in to batteries, the total capacity is less than 1% of global energy demands. Unless we discover new (cost effective) sources of lithium an order of magnitude larger than what currently exists, it doesn't make sense to place so much emphasis on Li-based batteries for large scale consumers like transport or infrastructure.

Fine. Use sodium then.

your still describing an incendiary device.

🐝 leading the way once again. honeycomb for president

This technology looks like it's not going to work, there's probably 100 different battery designs every year that just don't make it, this is definitely one of those, where is some information that could be gleaned out of this though

So would this boost the value of their shares??? Might wanna invest

Could you please cover what Amprius is doing? They state an energy density of more than 700Wh/kg for their batteries ...

Still dependant on Lithium.

Technology is moving so fast that we get a new breakthrough before we can industrialize the previous one

Be interesting to see one of these swapped into an electric such as a pipistrel

I constantly get confused. Is the lithium anode replaced by carbon? What is the cathode made of.?

So this layer prevents thermal runaway? I read liquid electrolytes create two or three degradation pathways so taking it out simplifies or reduces the constraints. Nevertheless, good info.

yes but does CATL have a energizer bunny equivalent ? like maybe a energizer cow(cattle/CATL) - please share your thoughts on this, folks with way too much free time would like to know
