Energy density of Na cells is lower, but it is the viable charge cycle count that is the show stopper issue for most markets. =3

Sodium has greater density than lithium, while most other materials used in a battery have similar densities regardless if sodium or lithium is used, so if a Na-ion battery and a LFP battery have about the same mass and stored energy, it is likely that the sodium-ion battery has a smaller volume.
