My understanding is that, at the moment Lithium Chloride is what they currently need for the solid state batteries, and there brine supposedly has a cost advantage, depending on the extraction processing used. I am not sure whether it is a to step or one step process. My guess, if they have a cost advantage as I have read numerous times, would be that they can go straight to lithium chloride with a different processing strategy than currently used to get to carbonate. I would not have thought the advantage would exist if they had to go via the carbonate step. It is precisely because they have to go via carbonate to get to hydroxide that they loose there price advantage in hydroxide batteries, partly because the quality varies too much for hydroxide and partly because they are effectively competing with chemical grade carbonate in that space, whereas the right spodumene can go straight to hydroxide.
