The CATL LFP batteries Tesla has been using already have only gone in the SR+ model, because they couldn't fit enough for the necessary range in the LR and P models, so in practice they do seem to use more space.
As far as I know they're not prismatic, they're using the same form factor as the NCA and NMC cells in those models.
- sudosysgen 5y agoThe article seems to say that these are the BYD Blade batteries so it would be prismatic, unless the article is wrong
- caf 5y agoI'm not sure it actually says that - it says that Tesla has signed a deal for BYD LFP batteries, and it says that BYD blade battery packs are energy dense, but it doesn't actually link those two and say "Tesla has signed a deal for BYD blade battery packs". One of the linked articles does report earlier rumours around Tesla using blade battery packs from BYD, but then also has quotes from BYD saying "we never said that".

- jacquesm 5y agoThat saves a ton of space, and if these don't have any cooling/heating requirements that savings will translate into a more compact pack which may offset some of the losses from the reduced density, as well as weight savings for coolant, coolant loops and pump.
- caf 5y agoThey are definitely heated at least in the Teslas, they don't perform well enough when cold.
