CATL’s first generation sodium batteries, shipped in Chery cars are $77/kWh
CATL’s lithium phosphate batteries are more expensive for now at >$100kWh.
Sodium batteries are definitely cheaper in practice, but much lower energy density.
The question is how far CATL can push energy density, and the second generation is claimed to be >200Wh/kh.

- oblio 2y agoEnergy density is a bit less relevant for grid storage, though. Not like you run out of space to put them.
- conradev 2y agoVery true. The other factors multiply, though, like reliability and degradation, because there are so many packs involved and because they're expected to work for, well, as long as physically possible.
