Of the couple dozen channels that I watch regularly, yours has (fascinatingly enough) the best content-quality-to-production-value ratio. I can't think of another slideshow video channel that I would follow so closely. Conclusion: very high quality narratives, and you are great at what you do. =)

amazing work bro. I recently discovered the true power that CATL has overt all the EV industry and this video help me a lot to clarify some points.

I applaud your ability to research topics that must be extremely difficult to get reliable sources from companies and indeed governments/countries not willing to share.

Excellent video, thanks for posting!

always enjoy your content!

Great presentation! Thank you.

Fascinating content. Thanks for sharing. Not only showing the fabrication process, but also the strategy behind.

At CATL, no one likes hanging out with the guys who work in the Cathode manufacturing side of the Lab, anyone know why?

Excellent video and presentation.

Nice video, good coverage.

Would you mind making a video that's taking a look at the Lithium mining industry? Ecological issues shouldn't be excluded from your awesome analysis.

Excellent work as always! Appreciate the detail and perspective across the industry.

7:16 from this version the staked is the better option for energy density. Because the second one haz to much pasive material(dont hold energy is just insulator) the 3rd one dont create potential energy in the same material(cathod or anode) in the inside bending. I dont know about manufacturing but instead of this 3 option exist one better wich is ROLL. Can be as tesla a perfect circle or an elipse option that is fast and can be made in diferent size just adjusting the range of elipse(easy scalability and for diferent consumer) after the roll in elipse formate is made squize it and done.

Great video, Thanks.

Good stuff thanks, One note, on T10:44, you have telling graph explaining the relationships between EV OEMs and Battery suppliers. Would we want to add a new set of matrices with Indian, American (with Tesla also a battery supplier) , and other countries who are OEMs and battery suppliers? Your commentary during this was a very important underpinning of how this chart is formed; that is, through shared interests such as investment and equity. The second, and a recurring issue for me is at T 2:44, the picture of the town. It brings to mind my home town, where the industrial sector, sea, Rail, and highway, and residential created (or did in my home town's case), a perfect environment for improved quality of lives and establishment of the home town culture. O course we didn't have high rises like we see all over East Asia, but factory homes of various sizes reflecting employment status. Thanks again for your work. I contribute to your channel via Patreon for a simple reason. I want to understand why my country doesn't do enough to increase (and yes you can argue it is in fact decreasing), its industrial capacity, and secondly how can we correct this. Nothing against East and Central Asia nations, or even China herself. I grew up here, and left for 20 years, 17 of it is East Asia, as I watched the now dead term Asian Tigers grown. I live here again, and coming home around 2000, I was dumbstruck by how my gutted hometown looked; hence, my avocation.

Thank you, for this video. Is there a group, where we can learn & share about companies. Their supply chain and share about industries in Asia to look for investing. Any suggestions? I LOVE YOU VIDEOS, THANKS.

thanks for sharing valuable content

Thank you for the video :D When gas prices are $10 per gallon, the _average_ people will park their ICE car and take a mortgage for an EV… but also, the electric bill will be $2 per kWh

Another interesting Chinese battery company is SVOLT which wants to become even larger than CATL! Please do a video on them. Thanks.

They showed me this video at a volvo factory in sweden, you have gotten far

very nice video, our company produces automatic formation, capacity grading, OCV, DCR testing, and logistic conveyor lines, is there any cooperation opportunity?

Great infomative videos u make but can u increase the volume of ur videos they do sound quite soft

Well done. Thanks.

thank you and posted to reddit

Please do a video on analog ICs /semiconductors especially on towerjazz semiconductor company

Cell manufacturing processes description does not apply to Tesla’s 4680 cells using tabless electrodes, and dry cathode/anode process (no drying toxic solvents)

I didn't know batteries had to be aged like whiskey and cognac. Very interesting!

Ultra sonic welding, man.

Do a video about Tesla dry battery electrode

Just curious why you have BMW as a possible competition for CATL

Very informative report on CATL. Thank you.

Hello, we can produce high quality flash graphene , in a large quantity up to 1 tonne per day. Do you have any practice in graphene usage?

thanks jon

Some added points of interest: 1. Tesla is buying CATL's LFP cells in the prismatic form-factor for its Gigafactory in Shanghai. These cells are used in the lowest-range/cheapest models. This is a departure from Tesla's preference for cylindrical cells. A good question to ask is, for how long will Tesla keep prismatic cells in its supply chain? In principle, cylindrical cells should lend themselves to cheaper high-volume manufacturing. The principle advantage of the prismatic form-factor is flexibility in shape, useful for conformal cells in electronics applications. Auto packs don't need conformal cells, so paying a premium for prismatic cells makes little sense unless some other motivating factor is involved. For Tesla, there is such a motivating factor - they want more cells than they can currently get. So accepting prismatic cells is probably only temporary for Tesla. It could be a fairly lengthy 'temporary,' though. Tesla's aggressive production ramp will strain their ability to meet needs for cells for years to come. 2. For Tesla's 4680 cell, they are using a dry-coating process that does away with the drying step you explained. It reduces the production line footprint, reduces capital costs, and per-cell costs. Going forward, manufacturers who don't use dry-coating tech in cell manufacturing will be at a pricing disadvantage. 3. Not every manufacturer is wedded to cell-module-pack engineering. Tesla is planning to abandon that approach in factor of cell-to-pack, no modules whatsoever. They also plan to bond 4680 cylindrical cells with a polymer to create a structural pack, which eliminates the need for trays and reduces the need for other structural body components, reducing automotive production cost and reducing vehicle weight. We should see these innovations first at Gigafactory-Austin in 2022. Note; structural packs are only possible with the cylindrical cell form-factor. Battery manufacturing is. at present, an exceedingly unstable business. Innovations are popping up at a rapid clip, raising the risk that fresh capital expenditures will become stranded before their costs can be recouped. Automakers are shifting their preferences, too - VW recently shifted their orders from pouch to prismatic, and they may shift again to cylindrical if Tesla demonstrates insurmountable advantages for cylindrical cell manufacturing, as they have promised to do. The road ahead for CATL and for other battery manufacturers is likely to be bumpy.

I've always wanted a battery operated car, said no one over 12, ever 😂

Microvast also export its products abroad ⚡️

Asianometry makes these videos just to prove they are better at pronouncing difficult words than us..

Information at it's best

What about EVE lfp batteries?

good

They're planning to open their 2nd European factory in my home country, Hungary near the city of Debrecen. Needless to say, the locals aren't too happy and it's a very heated and controversial topic at the moment.

LG Chem produced a bunch of barbecues for GM, so I'm not sure how much competition they're going to be in the future.

CATL get rid of the Pack in his New Qirin Batterie System and produce 250wh/kg in Germany. Thanks as always;)

Thank you. Great videos.

Great video and excellent analysis and detail!

It's hard to make batteries or just trudge patents mine fields.

Great video as always! I have one suggestion: it'd be helpful to display a map with the location when referring to certain cities or places, instead of only photos of said place.

How is this content free

I love your videos, congrats. If i could just ask you one thing, is that I wish the volume of your voice match's the average youtube video. For me at least when i come here, I need to increase significantly the volume, and then return back down when I browser other things. Either way i will keep watching :)

Not “winded” but “wound”.

Is it "Kaytle" or "see-ay-tee-el"?

2:30 Lost opportunity to say "the factories will produce batteries and battery accessories"

china is also pretty strong in optical fibers and photovoltaics production

Please be civil in the comments!

I feel informed after watching the video and will appreciate my phone battery even more !!!

I would rather see Panasonic in my EV . Made in Japan = Relability and quality.

lithium available

Catl does not own tianqi share.

New electrolyte prevents EV batteries from fire & increases range

10:43 outdated by almost 2 years. Tesla and CATL has a business

Like China requires, they will need to build a factory in the US if they want to sell here. It is a two way street.

16 cell modules are very common. 18 and 22 are next gen.

EV Battery Maker’s Sales Pitch to the West: We’re Not Chinese: But do you taste 👅 like Chinese and do you scream 🙀 like Chinese when eaten that’s what we want to know 🤤

I want to be Your Facebook friend.

FALSE! Microvast also exports it's batteries all over the world!

CCP Lemon Batteries FTW !
