The current cobalt market needs to double output to meet EV demand by 2025. 1.3 million tons of suitable nickel for 6.5 million tons of nickel sulphate globally by 2030.

Similarly, the report states that the cobalt market would have to double by 2025.
“To put this into perspective, to meet the incremental demand from EVs through 2030, an additional eight mines the size of Glencore’s Katanga would be required,” the document reads. “Wood Mackenzie’s AET brings electric vehicle (EV) uptake forward by ten years and sees EVs make up around 40% of passenger car sales by 2030. This considerably accelerates the demand for batteries and the raw materials that go into them.”

Even though at present the battery sector makes up less than 5% of total nickel demand, under WoodMac’s AET, the prediction is that it would rise rapidly to 20% by 2025 and 30% by 2030. Thus, an additional 1.3 million tonnes of nickel suitable for the battery sector would be required by 2030.
