Cut this from Western Australia Lithium magazine/web site.
I think that the Chilean Brine producers make carbonate as a raw product
Article:
Lithium has multiple forms, however the most important forms for manufacturing electric vehicle batteries are Lithium carbonate Li2CO3 and Lithium hydroxide LiOH-H2O.
Battery grade Lithium carbonate is used to make cathode material for lithium batteries, however requires a substantial amount of processing to remove impurities before it meets the required specification. Lithium hydroxide is also used for cathode material, however the hydroxide form can produce the cathode material more efficiently than the carbonate form. Lithium hydroxide decomposes at a lower temperature, reducing production time and energy costs for Chinese cathode producers.
Chinese domestic spot battery-grade lithium carbonate price (min 99.5% Li2CO3) sells for around $20 000 USD per tonne, whereas battery-grade lithium hydroxide monohydrate (min 56.5% LiOH.H2O) spot prices currently fetches around $21 000 USD per tonne. The premium paid for Lithium hydroxide is expected to continue as operators look to reduce costs whilst maximise profitability. However, despite the increase in popularity for Lithium hydroxide, the demand for Lithium carbonate demand is expected to continually rise steadily into 2020.
