Sounds like it.

Wikipedia has a decent (albeit somewhat outdated?)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.

Probably also just aa important to note that sodium is much more readily available than lithium and doesn’t require geopolitical wars or slave-labor to acquire.

Agreed, that is an important point. That being said, it was raised in the article, a more “technical” comparison wasn’t provided.

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.
