Wikipedia has a decent (albeit somewhat outdated?) comparison with other battery types.
Seems like sodium-ion batteries are somewhat cheaper, require more space and have lower usable cycles.
What's interesting to me is the power to weight ratio. Sodium-Ion is at ~1000 W/Kg vs Li-Ion at ~175-425 W/Kg. EVs could maybe have less weight and cost in the future because of this.
Sodium-ion has a lower power to weight ratio. Lithium is better in this regard.
Sodium-ion is used on the ground as storage for this reason. It's not to be beneficial to put it into a moveable object.
Depends on how close they can be made in watt-hours per kilo. They might be good enough for vehicles once the technology comes into reasonably widespread use, while avoiding a lot of the issues with trying to acquire sufficient lithium.
