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.

Power goes in, some of it is stored, the other portion is "lost" as heat/other. Then you can draw from the power that was successfully stored.

[@b.r.1523]

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

[@Cynthia_Cantrell]

Then you should try building some - it's the best way to learn! It can be done with very simple materials - like coins, salt, water, and cardboard... or a lemon and different strips of metal. Have fun and play with all sorts of different materials - it's a great way to learn!

The only (and important problem ) is still the Lithium supply chain. It is not really abundant, really dirty to mine and to recycle and it is linked with unethical acquisition and exploitation so still we need research in all technologies

[@clivestainlesssteelwomble7665]

UK work shows that lithium can be extracted from Geothermal power wells ..giving a 95% Li Carbonate purity.. and no need for slow expensive toxic stuff at the surface by comparison. The other options center on Na ... Al and Sulpher ... even if they use Li as a component the volume is vastly reduced. There are ways.... plus it's cheaper and easier to recycle old batteries than extract from ores currently.

[@andremarques3317]

with this technology, despite using another more part of lithium, will make every kilogram of lithium capable of storing more energy, which means an actual reduction in lithium need. Specially that when you consider that it will enable smaller batteries in cars, the less weight from the battery itself means you can move the car even more for the same amount of energy, which means the battery can be further reduced

[@larryc1616]

[@andreweliason713]

I am disappointed that the video begins with an improper statement regarding electron flow. Electrons flow from the negative terminal of a battery (cathode), through the circuit, and into the positive terminal (anode). To state otherwise diminishes your credibility.

[@TheWorld_2099]

I was looking at that and wondering…I had always known it to be the other way around. Thank you for pointing that out.

[@Emphasis213]

There are two types of theories regarding electron flow. One is electron flow theory and the other is conventional. How this came about is some guy got it wrong a hundread years ago with conventional theory. Then eventually someone figured out that electrons actually is - to +. 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.

The Tener is a standard 20-foot containerized energy storage system equipped with CATL's energy storage-specific L-series long-life lithium iron phosphate cells. The energy storage system has an energy density of 430 Wh/L and a total capacity of 6.25 MWh, which CATL said in April was the highest in the world. The Tener has a cycle life of more than 15,000 cycles, which is 1.7 times the current mainstream level, and will not decay in the first five years of its 20-year life expectancy, according to CATL. As a grid-scale energy storage system, Tener can integrate renewable energy sources into the grid, improving grid stability and reliability,

[@j.d.4697]

Can't go a single day anymore without at least 1 astonishing breakthrough.

[@steverobbins4872]

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.

[@MGZetta]

People acting like CATL is random lab in the basement that managed to write article by luck. Lmao. They don't realize who they discrediting. "Wake me up when it's commercially available." they don't know the only one that has resources to make these batteries commercial is CATL. lol

[@MrGHenchel]

I certainly appreciate the clarity of your presentations.

[@douglasengle2704]

I'm glad to see a video from people involved at a high level with the development of battery technology review the CATL condensed battery technology. 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.

[@gustavgnoettgen]

Like this one, presumably.

[@LiveType]

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.

[@arnaudmosse6894]

Why? wrong studies or just capitalist investors waiting to make x10 profit before allowing a new tech being mass produced ? like they did with microelectronics and the fake Moore Law !

“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.

[@jrobmccoy]

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.

The breakthrough for air travel would be for structural CATL batteries to be built into the carbon-fibre structure of an aeroplane. Making the gross weight of the aeroplane up to 60% lighter, allowing for a greater range.

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.

[@StitchesLovesRats]

The track you could barely hear was Francis Wells: "April Will Be Cold". It's a nice track and you can grab it from Epidemic Sound.

[@ZeroInDaHouse]

I never understood why the formation of dendrites couldn't be used as a feature rather than bug. These branches create an enormous amount of surface area. Perhaps some day a smart engineer out there can figure out how to use these trees to store vast amount of charge rather than run away from them.

[@gordongainer9146]

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.

[@karolinan976]

Could you please link your research papers?

[@christof.the.engineer]

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???

[@aerospacenews]

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.

[@PETERJOHN101]

ALICE is an electric commercial commuter plane in flight tests since 2022. It's expected to enter service in 2027. The 500 KWh threshold has been agreed upon by industry experts to be viable for large aircraft propulsion.

[@Michael-1337]

Solid states are supposed to be more stable on paper at least. However it looks like solid state batteries may never reach commercial production. The current batteries marketed as "solid state" aren't really a true solid state battery. It's more of a hybrid design using semi solid materials and gels. The problem with SS batteries is that they can't seem to overcome the internal resistance problems with them. For some reason SS batteries have a wide range of electrical resistance levels even when tightly controlling production variables.

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.

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.

@@peterbrown172 Oh mate, now you’ve stepped in a bit of a rabbit hole! Unfortunately, we defined anode and cathode for an electrochemical cell, like an electroplating bath. 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.

[@themacker894]

Nice video. You do a good job taking things that are complicated and making them interesting.

[@alsmith20000]

I was confused during this, Ryan spoke about these cells using solid lithium anodes but also said that the anode was a carbon honeycomb substrate with lithium on it. He also said that the carbon was honeycomb at the atomic level (isn't that graphite?). The diagrams he showed at 7:25 seem to be of graphite. The electron microscopy images at 6:45 appear to show a structure that has pores at about 200nm diameter (bigger than mesoporus). It could be that I'm confusing properties of the two different batteries but it would be good to have a comparison. As for the bio-mimetic polymer, it would be great to have an understanding of the way that it moves the lithium. Do these lithium centred cells get created on the anode, move across to the cathode and then get destroyed again?

[@cosmic_cupcake]

yeah, he was all over the place with the actual technical info.

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

[@El.Duder-ino]

Thx for the explanation👍

[@Kirmo13]

This is from April 19 *2023* Well over a year ago yet nowhere to be seen. I'm pissed in two ways 1) CATL announced this a long time ago and to this day there's nothing to be seen (which is pretty common with big tech) 2) you making this video as if it was just announced and already available. Like wtf, you have some duty to state things as they are.

[@WolfeSaber9933]

I'd stick with liquid batteries instead, as they are more adopted overall. You don't need second hand brick batteries when that size type no longer gets made.

[@rednectarchris]

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?)

[@9madness9]

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.

[@Alexus00712]

When can I expect them to be in every modern smartphone?

[@excell211]

They literally just added a honeycomb structure in the battery, and the youtuber literally says that the company didn't give much information about the new battery as a whole. In order to make a channel on the popularity of breakthroughs, you need to pretend anything is a technological revolution... :|

Thanks for explaining this.

[@gsestream]

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.

[@georgevieira4099]

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.

[@NoidoDev]

Available to makers, when? I need it to be available in the next 5 years. Small ones.

[@dougsheldon5560]

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

[@countmorbid3187]

As enthusiastic as i am for new WORKING batteries without the downside of Li-Ion batteries, this might mean resurgence of the EV madness. But the point that we produce so much "green" energy is far away. Solar and wind are way more polluting than ppl think as the EOL recycling is never mentioned. And that goes for the most polluting part of the EV, battery too. It costs as much energy to disassemble a battery as it is to make it. The batteries, if affordable, can be used in home systems and make energy greener. The "greenest" energy form is nuclear AND the safest with the least deaths per kW of all energy sources.

[@Radio_FM_3123]

I guess the highest Li battery should be Li metal.

[@Hybridog]

I hate to be "that guy", but is the gel electrolyte in the condensed battery flammable?

[@Rhaegar19]

If your battery shorts the whole thing is catching fire whether your electrolyte is flammable or not. But there are additives that can make the electrolyte non-flammable.

[@brealistic3542]

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.

[@JSmithDad]

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

[@shiekhwaleedmiral-protein2819]

Cant we replace lithium with a metal that's more readily available?

[@scottsluggosrule4670]

Let’s see how this self assembly works at -20C , need faster charging or still not much progress imo

[@vitormonteiro-f1z]

So they have already created it 5 years ago? and we only hearing it today?

[@TXDude]

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?

Hate lithium mainly because it's mining and processing hindrances. Sodium would be a better option because it's an abundant element and could be a byproduct of water desalination, if electrolytic process is used. Steam refining would still be needed but greenhouse evaporative pools shows promise🎉

Interesting , Thank you , I hope they work

[@sthsth2846]

Sounds a little naive, and a lot of cope. Also very simplified explanation of how it function and its mechanics. Honestly, a little bit dishonest as well since the different techs are pitted against each other as if one is better than the other when solid state batteries were explained poorly and as if it is inferior. Solid state whole reason is to go away from lithium not to use it as an electrolyte. I don't understand where that came from. In the end, if it ends up being a real thing and becomes commercially viable, then great! But I wouldn't hold my breath.

[@justinw1765]

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.

[@finn5571]

To be fair, solid state batteries still have several benefits that I'm not sure are addressed by this. As far as I understand anyway. For example, solid state batteries are much safer in context of punctures. That's not to say that this isn't incredible technology and doesn't meet a lot of the needs that solid state batteries were supposed to address.
