notes in its first par:

London: U.K, July 17, 2019 (GLOBE NEWSWIRE) --

Though spot prices for lithium compounds have been in a prolonged decline, long-term contract prices, estimated to represent over 75% of lithium trade globally, have experienced a different trend. Contract prices for battery-grade lithium carbonate increased throughout 2018, reaching a peak of US$14.86/kg before falling back to US$14.02/kg in Q1 2019. Prices for lithium hydroxide have displaced a similar trend whilst maintaining a healthy premium over lithium carbonate.Roskill’s Lithium: Market Outlook to 2028 explores how prices will perform as the industry expands rapidly in the years to 2028, detailing the relationship between lithium mineral concentrates, compounds and downstream products.

The report itself then points out, as@Kaeho noted, that

"We maintain the view that concerns about future refined lithium over-supply are poorly founded and expect the lithium market to enter a period of sustained supply deficit in the early 2020s."
