LFP more energy dense, last longer (by a lot) and have lower self-discharge. Sodium are cheaper and work better in cold temps, but add significant weight to cars, which makes this a less efficient application.
I suggest people not learn science by press releases.
I think Americans liking giant cars are a bigger issue with that than the weight of the batteries themselves.
CATL claim 10,000 cycles for their sodium battery which is way more than your article. Is selectscience.net a trusted source? CATL at least makes batteries in the real world but the burden of proof is on them this year.
While CATL has done work and has made real world solutions, I wouldn’t take their marketing material over the broader scientific consensus.
I am totally willing to buy that the market ends up between NMC and Sodium with LFP left behind despite having some advantages over sodium. Of course as solid state becomes a thing, that will be more of a factor than Na v. LFP v. NMC.
