Sodium-ion batteries are gaining attention as a potential alternative to lithium-ion batteries for EVs, mainly due to their cost-effectiveness and abundance of raw materials. Sodium is more readily available and less expensive than lithium, making it an attractive prospect for scaling up EV production.

I don't know why they said this — they really aren't a viable alternative for weight-sensitive contexts at all. Their density is only abut 60% that of Li-ion batteries, and that isn't even getting into solid-state Li batteries which are even more dense. If weight isn't an issue, like for home or grid backup storage, they're fine. For cars or bikes, not so much.

Unless we get to the point where we do battery swaps in cars instead of charging. Just pull the fusion core and pop in a charged one. If we can do it for propane tanks we can do it for cars. Run out of "gas"? Tow company can bring you either a full charge or a smaller battery to get you to the next swap point. Most likely this will start with cross country trucks, the owners can have swap points or drive out a battery for a truck that ran out early.
