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.
Question is… How much cheaper…
LFP is almost at the price point we could all have a freezer sized battery pack in our house, drastically changing the grid, and allowing a place for all that wind/solar to store energy.
If Sodium is a fair chunk cheaper, then it will totally be worth buying a house battery pack. Buying energy on the cheap at certain times of day, and using the battery when energy prices are high.
Potentially 1/10th the price according to this video I stumbled on about it a couple of days ago!
