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.

Maybe in the sense that there'd be less competition for the relatively rare materials needed for EV batteries?
