Those 5 advantages are very important, but you haven’t mentioned its disadvantages which render the advantages less dramatic.

A significant disadvantage is the lower energy density of the sodium battery chemistry. Implications include faster discharge/lower range if the physical dimensions are the same as a lithium battery, or if optimized for more range/power, then it would be a larger and heavier pack vs lithium with the costs that entails.

This lower energy density is one of the main reasons it has been considered more suited to stationary application because the extra space and weight is less problematic than in a mobile applicaiton
