Roskill sees recovery in lithium industry, buoyed by demand from rechargeable battery applications

Green Car Congress

In its new Lithium Outlook to 2030 report, Roskill notes that the prolonged downward trend for lithium compound and mineral concentrate prices has caused a difficult environment for many lithium producers since 2018. In 2019, monthly average lithium carbonate prices fell 36% between January and December.
