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.
As long as the efficiency is outweighed by price, it could move us in the right direction. Hopefully we can pick up the efficiency in time. These would also be good for my future load-shifting (charge during off peak, low carbon electricity) and maybe solar system at home.
