According to a recent report, Tesla is working on 4 new 4680 Battery variants including a version that will used in the upcoming Robo Taxi, Tesla Semi and more which I believe to be an LFP battery type.

Jon, thanks for all of the interesting info in this video. I have a couple of thoughts:

Going from a "Workhorse" description to LFP chemistry is quite a jump. I expect "Workhorse" means that it will be high volume and used in many vehicles. Four different vehicles are listed which supports my view, IMO.

Elon and Drew have mentioned in past quarterly earnings calls (after battery day, but many quarters ago) that the 4680 format is not right for the "physics" of LFP chemistry. My best guess is that they are referring to the flat voltage vs. SOC curve for LFP. That makes cell balancing not work well between cells wired in parallel. Note that most (all?) LFP packs don't have cells wired in parallel. Instead they use large cells that are wired in series only. This supports my guess, IMO.

I could see the Powerwalls done in the USA going to tesla made LFP also. They don't need 'high performance' since they are more bulk storage than immediate need high power application.

It is well known that the problems with 4680 were solved a couple months ago - reason why they volumes have been ramping up significantly.

[seancollins]

the goal for 4680 was ALWAYS LFP, it was in the original slide deck from battery day.

Silicon Carbon is not the same as Silicon. Yes they both contain silicon but the structure of the granules are different. Silicon Carbon is engineered to have room for expansion inside the granules.

[leesweehuat]

The higher power density 4680 batteries type are unlikely to be the LFP battery type? Also the Tesla Cybertrucks and Semis will be the key demand drivers for the higher power density 4680 batteries, at least during the initial period of the 4680 battery production ramp?

[Voidroamer]

what about the one that qualifies for tax credit?

I thought the Limiting Factor's Tear down showed that Tesla had not put Any Silicon in the anode

[JRP]

Cylindrical LFP wastes a lot of space compared to prismatic. Other companies are already building prismatic LFP into structural packs, (BYD Blade for example).

Initially the report was cathode sorted will be in vehicles 4th quater this year. Then first quater next. Then second qyater bext. Now middle o next year which means 3rd quater. A year late even after they solved it. This must be hellova problem to solve 😮

Will this burn my house down if it is flooded with saltwater?

[TheLastMoccasin]

You said "there's a reason why (not only because of battery supply) the Plaid uses 18650" .... Lucid uses 2170 and has even more performance than Plaid so I do not think your performance hypothesis holds water unfortunatly.

[hedleypepper]

When tesla release a 250 mile range rwd cybertruck it will indicate no more demand

[jolive]

aren't unnamed sources supposed to be ignored?
Simply put, many of us bought in all those years ago, on the basis of what we heard on battery day (as the ones with the most/best batteries will likely win) and it's been a bust, let's be honest

[batterylabs]

What a Cybertruck disaster, pure junk

[DCGreenZone]

Gee willickers, who invented all this "New" battery tech. 😂

[TheLastMoccasin]

Kind of sad that their demand has fallen so far that they haven't been cell constrained for years at this point. That used to be the limiting factor to their growth for a long time. 😥

Sadly, because of Elon I will not be purchasing my 3rd electric vehicle from Tesla, even though I love my car.
