Sandy Munro just covered Sakuu's dry cathode progress. They already have working pouch cells.

Tesla uses extrusion to mix the binder with the active material. It is a completely dry procedure. Maxwell's patent is actually about this extrusion process.

Love this channel, awesome, thank you a lot for such great content ❤

You're welcome! I am glad you enjoy my videos.

Competition and innovation at work.

Jon.... (Speaking as a Photocopier/Laser Printer Technician) That "dry powder" sounds *A LOT* like a copier/ printer TONER. A brief description of part of the "printer" process..... . An active material combined as a dry powder with a thermoplastic binder.... (Here's the bit they SHOULD use imo) Electrostatically applied to a surface in a fine (variable thickness) layer, then "fused" using heat and pressure. . Sounds like that would do it? . There are probably ways to utilise the toner transfer process with a photoconductive drum via a toner transfer belt system. That would allow for an extremely precise snd accurate coating. . The only issue might be use of a metal foil in the transfer process, but I'm sure the "Smart people" at a copier company could work that out.....

Sooo, the guy from LG wrote an "article" saying they're the leader, and you're reporting they're the leader. Nothing like social media for the facts.

How come you have not reported on US silicon battery companies Sila Nano Tech and Group 14 ? Apparently 50% improvement energy density and charge speed if cathode has 80% silicon. Thoughts?

I’m pretty sure Maxwell Technologies worked on DBE for years before Tesla purchased them. The Tesla tech wasn’t born yesterday.

So is the danger of spontaneous combustion due to modes of failure still part of the problem??

I didn't see a Broken Trough anywhere.

Since it is a "dry " process is this considered solid state?

@Cleanerwatt

18 күн бұрын

No. The term solid state refers to a battery having a solid electrolyte versus the liquid electrolyte in a traditional Lithium Ion battery.

Thanks for this. I've been wondering what it is that has been holding up Tesla's development of the dry-electrode process, and your thoughtful video introduces some very interesting possibilities. It seems that most of the time, persistent and intelligent efforts to solve an engineering problem will yield the desired result. And sometimes. . . that's just not enough. Sometimes, the solution awaits some sort of breakthrough. Very hard to time breakthroughs.

What your though about Sakuu's ?

So, they've been doing this for 10 years and Tesla does it and all of the sudden we are hearing about theirs. Interesting to say the least.

Tesla bought a company that was developing it. Seems like no one has mastered it yet.

The current EV rated at 320 miles of range will improve to 375-380 miles in 4 years? 5 years? Assuming same size battery.

DAM Following Tesla strategy of "The best part is no part", instead of adding an extra material and process to act as a dam you could presumably just introduce a crease in the substrate foil to create the dams. I'll take my patent now please 😊

Do the LG batteries with dry electrodes also catch fire randomly?

Did you sort your books by color? 😵

Apparently you haven't been paying attention. They dissected a current 4680 and it was determined that both the anode and the cathode were done with a dry process.

That'd be nice... never heard of a battery or capacitor that didn't degrade as it was cycled yet though. Oh wait that molten salt battery might not...but its components are liquid, so there's no solid structure to degrade.

Is that Gravimetric? Or Volumetric? . IF you were paying attention you would know both are improving all the time. . Of course.... YOU are looking for the "OMG... NUCLEAR FUSION!!" like leap... That's NOT how it works. . It's an incremental advance, sometimes with multiple facets combined. . Don't forget they DO know what's coming.... But to make the "generational leap".... Let's say "50 year life , 10 minute charge" they must TEST THAT BEFORE RELEASE. HOW do you test a "50 year cell" for not just performance but *RELIABILITY* ? (You don't want a fire risk from an ULTRA high energy cell, do you? Think that through) . Intensive testing for...... 5(?) years? Maybe? Do YOU know?

Owning an older patent doesnt guarentee superiority. LG began its battery development in the early 1990. Maxwell on the other hand focused on ultracapacitors and much later on battery technologies.

Tesla makes their own dry 4680 battery cells at Giga Texas with DBE tech and use them in the Cybertruck and previously in model Y AWD (standard range), and they buy 2170 cells from Panasonic and other battery manufacturers and use them in model 3 and model Y, and they buy 18650 cells from Panasonic and use them in model S and model X. They also buy LFP cells for model 3 and Y (standard range) from CATL and maybe others, and I don't know of what cell form factor. Anyone who knows?

leader? Since SONY's first successful commercialzation of LIB in the early 90's, Japan (and Korea later) led the industry. The US was behind many breakthroughs since the 70's, but wasn't really big on manufacturing and more or less ended when A123 went belly up many years ago. Japan & Korea likewise own most IP in this business -- China was very late to this game; however they now dominates low-end battery market. bite me
