My understanding is for batteries lithium is the less tricky one because it doesn't change size during redox reactions. Sodium does and that damages the anode or cathode (can't remember which, don't care). Yeah and the low production of lithium is due minimal demand historically. It's not like other metals with a large historic demand. Like copper.
