Another potential use for sodium ion battery tech is in grid-scale storage systems, like those mentioned here;

(#HatTip to @norightturnnz for the link)

I have no idea what chemicals are currently used when building such systems. But if they're lithium ion they'll be stupidly expensive to build, and if they're lead acid - which seems more likely - they'll need replacing much sooner.
