"Compared to lithium-ion batteries, sodium-ion batteries have somewhat lower cost, better safety characteristics (for the aqueous versions), and similar power delivery characteristics, but also a lower energy density (especially the aqueous versions)." https://en.wikipedia.org/wiki/Sodium-ion_battery#cite_note-:...

Also, recent CATL PR releases about sodium ion only mention 'future cost savings' rather than anything about a 90% reduction in prices.
