Go to slide `13 - 23 of this link. Conceptual but interesting - power savings are largely because of the view it takes less time to get to the end product using Calix than conventional means.

Li(OH)2 is different to LiOH in that it has two hydrogen atoms, so process appears hydroxide based - what PLS has committed to is a lithium salt which it defines as an intermediary, which I think is more atune to sulphate as per earlier post.

Anyway, Calix are doing a lot of R&D in the area so looks like they intend seeing how the process works using PLS spodumene by the looks of it. As I said will be interesting how the process works at scale instead of a pilot plant, which I presume is the initial tests. As I said game-changer if tech works for all, but a lot of water still to go under the bridge.

They have their finger in a number of pies trying to devlop low carbon processes in production - here is some others outside batteries:
