The only mention they have of cost is "Since the chemical components are cheap, a scaled-up industry should be able to produce batteries that cost less than their lithium counterparts." They do not mention its a half to a third the price of the two prevailing technologies and they they have weaselled it with "should". It does cost less already, you have been able to buy sodium ion batteries on aliexpress for months and the cars are already out from BYD and many more are scheduled later this year and into next. The article is mostly about the geopolitics of the materials. So I stand by they don't mention it, I read that article and I felt this was the key missing context as to why Sodium batteries are going to matter.
