Cobalt is considered the highest material supply chain risk for electric vehicles (EVs) in the short and medium term. EV batteries can have up to 20 kg of Co in each 100 kilowatt-hour (kWh) pack. Right now, Co can make up to 20% of the weight of the cathode in lithium ion EV batteries. There are economic, security, and societal drivers to ...

The results indicated that the main cobalt mineral type (cobaltite, linnaeite) had only minor effects on the evaluated impact categories. With cobaltite-dominated ores (High As case), the global warming potential (GWP) was estimated to be 20.9 kg CO2-eq, of which 12.7 kg CO2-eq was attributed to the hydrometallurgical process.
