Apparently BYD will be releasing one of its models with a sodium ion solid-state battery this year. That is, it's verified and working and ready to ship.
Your link says "may" not "will", and is from December last year.
I shall keep my fingers crossed that it does happen, but with no "They're actively being manufactured right now" news articles, I'm not hopeful that they'll be available to buy in the next two months.
