energy density of 175 Wh/kg
CATL explained that sodium-ion batteries have slightly lower energy density than lithium-ion batteries but provide distinct advantages in low-temperature performance, carbon footprint, and safety.
One downside is that compared to other solutions this is a really heavy battery afaik, but honestly having no fire hazards and way better lifespan totally worths this tradeoff
The energy density claimed is higher than any current LFP, so it would be lighter.
The energy density isn’t bad. A lead acid battery has 80Wh/L, and a sodium ion battery is 250Wh/L. Now high-end lithium ion batteries can reach 600Wh/L.
