Yeah, when did Elon say Tesla
would make 4680s with LFP cathodes? Or more importantly,
why would they? Partners already have leading-edge tech in LFP (ie: BYD Blade, CATL MP3), and the is no shortage of supply of capital, raw materials, or capacity: The LFP 4680 issue was addressed in this video 7 months ago:
No, Tesla Will Not Be Making 4680 LFP Batteries | The Tesla Economist (Jan 18, 2022)
Tesla does not need to move into the LFP production space: it's moving fast on it's own. I expect Tesla has already purchased at least half of this planned future volume:
2025: CATL's 1200 GWh Planned Capacity // + Tesla Cell Supply Forecast | The Limiting Factor (Nov 17, 2021)
It's high-nickel, high-performance for the future of 4680s. I expect Tesla will have an aviation ready 4680 cell in 10 years.
See above. Tesla goal is to obtain a massive supply of batteries at a good cost. The best way to do that is through competition. When Panasonic was too slow/unwilling to invest in further production in Nevada, Tesla started the 4680 project (remember when Tesla bought Maxwell Systems? That was way back in Feb 2019 - that's how long of a lead-time is involved with scaling new technologies).
Tesla still isn’t getting enough batteries from Panasonic - The Verge (Apr 11, 2019)
Now, due to this 'prompting' by Tesla, Panasonic is building a $5B battery factory in Kansas:
Panasonic to build EV battery plant for Tesla in U.S. state of Kansas | (Jul 14, 2022)
That's how you get top performance out of your suppliers. Single-sourced 2170 cells? Buy more from LG. Need better prices on LFP? Buy from BYD and CATL. Best tech wins in the virtuous cycle. But Tesla doesn't have to do it all themselves, they just set the specs and the $$.
Cheers!
