The waste level is the real breakthrough here. A cheap reagent (ammonium fluoride) for something so valuable (battery manufacturing at home) in such a timely manner means this is going to happen at scale.
Ammonium fluoride looks pretty nasty (and I know enough chemistry to not be afraid on chemical names and I even can write the formula without looking NH3F).

Is Lithium so expensive? I'm not following the market, but I guess anyone with a big salt lake and some processing can make it. It's just cheaper to do "abroad". [Hi from Argentina!]
