I'm very intrigued by the growth of these tubes. I hope to see more on this technology

No. This was long on promises, long on fluff and very exceptionally short on actual data or even a sample battery.

This is alchemy

Reminds me of the filaments of asbestos. Could this be a health hazard in handling when recycling?

It's a nice science experiment, but it's always hard to believe that CVT can get the throughput for something that needs to be as cheap as battery electrodes. That said, they are dealing with quite short CNTs, so 30 seconds isn't terrible, and if they go to even smaller coating thicknesses (lower energy density, higher power)... maybe? :) The other issue I'd *really* want to know more is their cathode chemistry. As a general rule, all the methods I've seen to alter the cathode chemistry to prevent the polysulfide shuttle problem dramatically reduce the energy density.

@@nononsenseBennett interesting insight, recyclability is vastly important I would think.

​@No Nonsense Bennett only 5% of asbestos was crystalline (cannot be easily expelled from body by cilia&mucus) - the majority was 95% amorphous and easily removed. The hysteria over asbestos was initially ginned-up by the Trial Liars and their well-paid so-called expert witnesses from the lower echelons of their graduating class. As always, once the hysteria gets going, it's impossible to stop. Analogous to bank runs on o/w solvent banks, planetary global warming hysteria even though we know other planets in solar system also warming, shipyard workers getting lung cancer while insulating hulls and smoking 2 packs/day, EMF cancer claims when HV Line workers have no increased cancer rate than genpop, etc., etc., ad nauseum.

@@nononsenseBennett just don't inhale it lol

What’s interesting is that they have really failed to implement the gains of that technology i.e. battery day. They have only really implemented a couple of the bunch of innovations i.e. 4680 form factor, tab-less and battery frame. They are struggling to scale the dry coating tech which is key to reducing complexity, cost and waste and I think there was 1 or 2 other things they have yet to deliver on. Hopefully they will get there, but I think they are some time off by the fact they are asking for suppliers for generic 4680 cells.

@@Gareebaa84 Perhaps you missed the Investor Day comment where they confirmed dry battery anode and electrode problems were solved at scale.

@@marknevar8234 indeed I did. Thanks. Still skeptical, why order 4680 from other suppliers if after 2yrs investment in scaling up they don't have the capacity yet?

@@Gareebaa84 About the only thing they had failed to deliver on was price, and now prices are coming down as well. The big miss from battery day seems to be the $25k car... now theyd rather sell a $25k robot to take peoples jobs.

@@patreekotime4578 I think you agree price was intentional. There's no reason to reduce price given the demand. U saw them experiment with that price lever recently and now they are sold out again

Hah, I’m sure there’s no “probably” about Sandy’s ability to retire if he wanted to 😁

@@DEtchells no doubt but he obviously loves his work. too bad most people can’t do that

@@johnjaeger4804 I love your father and there is no "probably" about his ability to push back.

What's the secret of your currently well working brain?

@@bui340I wish there was a secret. But it's just repeated exposure to this kind of stuff.

@@bui340 His neurons have achieved peak gradient descent

Dendrites will ALWAYS happen due to dissimilar materials etc, the Q, is how fast they grow before another failure happens.

@@w8stral Their explanation about swelling resistance seems credible given the CNT forest-swelling should fill in the gaps not “out”. The cathode sulphur migration mitigation seems credible. But dendrites ... they suggest it’s not a problem but will need to show in details why.

@@Georgewilliamherbert No, they did not say dendrites are not a problem just that their design severely hinders dendrite formation rate. True, they did not use the word rate, but that is the simple truth for any dissimilar material.

I think it's about the nanotubes having oodles of space around them to soak up the Lithium.

re: "I'm not convinced they have eliminated the dendrite issue." exactly those who are astute/paying attention will recognize how they are not the first to claim to have resolved this issue. in fact those in the chat who aren't "baby young to the world" will recall how we heard all this same HYPE and CONJECTURE in regards to Super Conductivity back 30+ years ago (ref: circa 1992) yeah "Pepperidge Farm Remembers". now I know it's hard to believe but the 4 men speaking in video are not REMOTELY the only people with decades of Engineering experience across a variety of sectors. no, for example the Auto Industry alone employs over 10 Million people annually, so that roughly leaves another 99,999,996 talented and experienced people you haven't heard from. in fact I just flew back from Salt Lake City having spent a week with 24 others including myself.

Well, when someone invents a moving mass produced lithographic machine this battery tech can become possible, until then, this is a pipe dream.

Actually, that should be “… other than charging and the total inability of our grid to supply the required energy” (Maybe that’s what you meant by “charging” though.)

​​@@DEtchells ... and the complete inability of our current infrastructure to provide the dozen-or-so supply constrained raw materials at the rates needed (10× or more) to convert an appreciable percentage of the global automotive industry to EV's. Not to mention the massive recycling facilities that would have to be constructed as well. ☹

@@briandbeaudin9166 Yeah, all that too. It's an even bigger issue than the grid, but either is a showstopper on its own. It's just incomprehensible to me that the "green" forces are shutting down reliable energy production at the same time they're investing billions (many hundreds of them, probably trillions globally) in trying to force an impossible changeover to solar and wind. (And it's clearly not about saving the environment, as any rational person who cared about CO2 would realize that third/fourth-generation nuclear is literally the only non-CO2-emitting way to provide stable baseline generating capacity.) Our energy policies, hundreds of billions dollars of expenditures and the resulting impacts on global health and peace are literally and entirely based on fantasies 😖

evs are not even possible even with new batteries you people are so blind we need 10x more copper, 10x more silver 100x more quartz for it to be even maybe feasible and it isnt and we just lost 40% of the worlds material in Russia and Ukraine for the Jews but even that statement will come off as hate to you, because you have no idea what is going on in the world or what reality is. Of course maybe I am deluded as well but I think I know the truth. Can one ever really know

Thanks! Will do!

@@MunroLive tell these guys to show up with a working cell. If they don’t, which I have yet to see them show a single working cell, tell them to get lost.

@@banme2784 Zeta's working cells have had validation from two different government labs!

Agreed, big talk seems easy for battery companies. Especially when it comes to cycle life and power density

​@banme2784 I am with you on this, there's a lot of pipe dream here and everywhere. Before Munro starts interviewing companies and "Flannegans pipe dreams" Thay need to bring a batch of batteries say a 100 so that Munro can test them. Then sit down in have that interview and talk about the batteries. All of this may be a pipe dream.

🤔 maybe something TESLA could use 🤷‍♂️💚💚💚

@@MunroLive huge difference between china and japan dipshits, japan wasnt our enemy after ww2...china is our current mother fucking enemy just like japan used to be pre ww2 you stupid fuck, plus tesla's charging network sucks i live in one of the most heavily populated area's of virginia and there is only one charging station in the entire city and it's @ the fucking mall lol what a joke electric vehicles are a fucking joke plus junkies cutting copper cable on charging stations and trading it in for cash for drugs you can run without catalytic converter by the way if junkie snatches that it doesnt make the vehicle inoperable unlike cutting copper cable from your power wheels charger they are heavier and wear tires faster shittier for offroad because high centered less open spots under the vehicle for rock or something to go in they wear down our roads more and we can hardly keep them maintained now muchless millions and millions of ev's the power grid cant handle millions and millions of ev's plugged in either they cant tow for shit they lose range just sitting in heat or cold unlike gasoline, charging times are dogshit they're a major fire hazzard you cant just fill them up with a can of electricity whats cheaper gas can/grabbing acouple gallons or thousand dollar portable battery pack that would take 60 hours to give it 2 % juice lol if you run out. they will be monetized pieces of shit the whole things terrible besides electric vehicles are out of date technology compared to ice vehicles, 1832 vs 1886, the design of electric vehicles trash also they are adding way too many things that are going to fail on them even somerthing as simple as charging port door or door handles its all one laughable joke besides all the stuff used to make batteries are finite resources just like gasoline and even more destructive to habitats. Besides they're a bitch to even tow the fuckers if you break down lol FUCK YOUR GODDAMN POWER WHEELS SOUND ABOUT RIGHT?

Funny, sounded like some nonsense without real data. They didn't even bring one along to show off. Many specs not mentioned. Its early days but surely if they are testing for thousands of Cycles and have some laying around on cupboards . Then they have time to make a few to give for independent verification and demo purposes. But ueah still pretty good in general

But Sandy wants to know, "What was the Frunkin' parking cost?"

@@FrunkensteinVonZipperneck 120€

I just saw your comment. I posted essentially the same question. Zeta said they had mitigated the gassing issue. In prior Li - S, the gassing was elevated levels of ethane and methane due to electrolyte decomposition. Elevated temperature is 30 ~deg. C, so really not that elevated. Capacity loss is related to the gassing, so maybe Zeta has also effectively improved the working temperature range. I guess we’ll see in about four years (2027).

@@wtmayhew Being able to charge at 10C rate without any gassing expansion sounds like temperature isn't rising much, doesn't it ? That would cover part of the temperature management issue -- cooling while fast charging. Did they mention operating temperature range for charging and discharging ? Being able to charge and discharge with ambient from -20c to +50c ? Being able to eliminate the need for temperature control on a pack would be a huge cost savings.

@@kirkellis4329 Thank you for the reply. It seems like we’ll have to wait (or at lest I will have to wait, given my limited chemistry expertise) to see if Zeta really delivers. If/when Zeta gets their cells to market, they’ll have solved several thorny problems which have annoyed others with Li - S cells. Indeed a 10C charge rate would be applied repeatedly without serious deterioration would be quite an accomplishment.

@@wtmayhew I didn’t know about the gassing issue. My question pertains to the car being parked, charging , driving in Arizona during the summer or Norway in the winter.

@@steffenfrost I pretty much have the same question. Zeta made the pitch, suggesting their technology is appropriate for a cylindrical container. Going to Zeta’s web site isn’t very helpful in explaining how Zeta is addressing the known technological problems. That is understandable, given the need to keep some things proprietary. I am given a little pause because the News section of Zeta’s site is mostly about who’s been promoted to what position rather than about field deployments and trials of their technology. For now, we have to sit back and see what’s next.

I think you're looking at the prototypes tested last year -- the cells being developed now are expected to have 450 Wh/Kg (almost twice Tesla's density) at

@@melissaschilling1138 The 2022 cells have about the same gravimetric density (specific energy) as Tesla 250-300 Wh/kg per the chart. It is the volumetric energy density where they seem to have a disadvantage at 450 Wh/L vs. 750 Wh/L for Tesla 4680, according to the chart at 9:30. I agree that Li-S is a much more promising chemistry if it can be commercialized. It would be interesting to see cycle life and calendar life data for the Zeta cells.

@@georgepelton5645 And lithium sulfur should have a significant cost advantage and supply chain resiliency advantage given that it does not use nickel, manganese or cobalt.

Sounds to me like good chemistry for future 4680's!

There's a slide at 9:31

Glad you liked it!

Thanks!
