Yeah, that makes sense! The drive has been not only for higher density, but also lower cost. Sodium batteries were investigated for cost reasons (to avoid the Lithium) and it turns out that density isn’t as good (for now), but that’s okay for some cars and great for stationary storage. Enough demand to drive innovation. A cord of wood is hard to beat on cost! My understanding on sodium is that it’s still early days. Most “sodium” batteries shipping today are hybrids with lithium (two sections, one bms) with poor cycle lifetimes, so there is a lot to figure out still. I haven’t personally seen or heard about CATL’s sodium batteries in the real world yet.
