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.

The numbers I've seen: LFP: mid 90s Sodium: low to mid 80s

LFP seems better for cars unless you live in an area that deals with extreme cold. Sodium is better (cheaper) for fixed, large quantity storage where energy density is not as critical and lower efficiency is an acceptable trade off for lower price.
