New Tesla battery? Exploring the China prismatic LFP news

New Tesla battery? Exploring the China LFP news. Reuter's broke the news that Tesla was switching to CATL's prismatic LFP battery from their standard cylindrical NCA battery. I wanted to dig into a little more detail on the differences between the battery formats, how they’re made, why they’re chosen, and what the change in battery chemistry means. Including the fact that the CATL batteries don’t use cobalt.

Correction: The Nissan Leaf uses pouch style batteries, not prismatic.

[Wingmantws]

the battery management system can't target each cell as you say at 4:20, it can only target each parallel group. Tesla does use a small wire as a fuse to connect each cell though, so if a cell shorts out it will blow that fuse and disconnect itself. The bms will not know directly that this had happened, it will just see less over all capacity from that group.

Hey Matt .... 5:20 . Nissan Leaf doesn't use prismatic cells. It is build out of pouch cells. Early 24kw used 4 pouch cells in a module and 48 modules in the car. Later 40kw's used 8 cells in a module and 24 modules in the car. Great videos as always. Keep up the good work!!

There are only 3 kinds of people in the world.. Those who make things happen, those who watch others make things happen, and those who have no idea what's happening. Thanks for keeping us out of the third group Matt. Subscribed.

I think we need a discussion on battery chemistry V charge time as that seems to be a critical factor to drive EV ownership

[DirtyTesla]

Great video. I always wondered about the volume loss from cylinder, but makes sense with Tesla's cooling.

I'm still a little annoyed with Nissan making their batteries degrade so quickly as that stigma is still around.

[incrediblehulk]

Wow your channel has grown. Come from high quality videos and audio. Congratulations

[longboardfella]

Thanks for the update Matt. Answers with Joe recently did an update on cobalt and covered the various battery compositions

[matthewconnor]

Could LFP find its way into storage systems? In static application power density is less critical then in EVs so the cost saving for grid scale applications could be significant while also freeing up 2170 cells for EV production.

[Tuckerclan]

It's always interesting to me to watch somebody as passionate as you are about the future of this technology. It gives me hope for our future as a species, especially considering the current state of affairs.

3:47 - That loop is older S. Model 3 has a log manifold style

[JustfishNascar]

Matt, I really like how you break down the subjects to manageable chunks. I think I'm tech savvy and understand some of this material, but when I look at your breakdown I realize I'd be lost without you doing the back end work for me.

[tomtedude]

Thanks Matt, for breaking down the differences between the types of batteries and their pros and cons.

[ontopoftheroof]

The single largest use of cobalt is for desulphurisation during refining crude oil to fuels like gas and diesel. This cobalt cannot be recycled as it remains in the fuel and goes out the tail pipe.

[macgibbon]

The detractors who talk about batteries using cobalt never seem to mention cobalt being used in the manufacturing of petrol. Weird, huh?

[jedics]

Im currently using the prismatic LFP's in my off grid life, they were the only choice after my research because they are a proven tech over a decade, are completely safe and while don't have the energy density of Tesla's chemistry they aren't that far behind and this doesn't matter for house power. They charge and discharge quickly and have a long life and best of all they make sense financially if you shop around and put it all together yourself.

[LarsPallesen]

Good job, Matt. I really appreciate your clear and concise breakdowns with good graphics and relevant footage. Thanks!

[ramonpunsalang]

Prismatic architecture + Tesla Secret Sauce should hopefully result in a competitive advantage.

[TeslaElectron]

Great in depth of Battery architecture Matt. Great Video. Lot of work in that buddy, great job.

Hello from calgary alberta. I hope the battery changes everything
