Potentially game-changing.

Let's hope scale-up of this method proceeds quickly. The world needs massive amounts of battery storage to de-carbonize our industry, transport etc yesterday. Time is running out.

And being able to tap into more sources of lithium doesn't hurt either.

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.
