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.
Why wouldn’t the grid do this on an industrial scale and remove any off peak discounts?
Potentially 1/10th the price according to this video I stumbled on about it a couple of days ago!

That video makes it sound exciting but I’ve heard Matt hypes things up more than they should be
