Not Gunna Be Enough Lithium, page-418

How high could lithium prices go

Well, you have to look at other materials to be your guide and that’s what we used in our approach. To cut to the chase, we suggest that lithium prices, which are already up 500% from the Q3/20 trough for SpodCon and 700% for BG lithium carbonate, could rise as high as 1300% from the trough.

So, to put that in plain numbers, that’s SpodCon prices of over US$5000/t and BG lithium carbonate prices of over US$60/kg in this cycle. That’s compared to SpodCon prices now of US$2360/t, China spot BG LC prices of US$38.8/kg and contract prices around US$20-25/kg. So, that’s still quite a big increase from here, for all those cautioning that the lithium event is over.
