LFP v’s NCA… and the winner is…

Contrary to claims made upthread, Model 3 LFP cars are not slow by any measure relevant to normal street driving

Yeah it’s just the RWD LFP Model Y that has the pause in power off the line. Feels like it’s electronically hamstrung to save the battery or something. Wierd and annoying.

Did you mean "below 20%"?

Nah below 20mph/40 kph the LFP MY is as slow as anything. Like it’s electronically restricted. It’s plenty quick enough above that speed.

According to this article:

EV LFP Battery Price War at Less Than $56 per kWh Within Six Months | NextBigFuture.com

CATL has new rectangular LFP batteries. The LFP EV battery price will be less than $56 per kWh within six months. It is a bigger rectangular battery with each

... LFP batteries were at 120 dollars/kWh at the start of 2023 and are on track to be just 36 dollars/kWh by the start of 2025. That's truly an insane scaling of value. Heck, just knowing the pack could be easily replaced at a reasonable cost would be hugely inviting.

And the fact its good for a lot more cycles making a replacement far less likely in the normal lifespan of a passenger car. For heavy duty trucks like the semi its a different ballgame as the expected useful life is around a million miles so its significantly more than passenger vehicles.

Interested to see how the different BEV semi packs hold up long term as that will give some insight into passenger vehicles.

The NMC type cells are not dropping a ton on cost because the cobalt only comes from a few sources, none in stable areas, and there is also the whole child labor issue with it. This is a big reason why cells that use much more common elements are desirable, the materials are readily available from multiple sources. Its much easier to find iron than cobalt!
