Some key materials used for manufacturing lithium-ion batteries are lithium, cobalt, nickel, manganese, and natural graphite, which come from more than 30 different countries. In 2017, Australia, Chile, and Argentina produced 91% of all lithium while the rest of the world supplied the remaining 9%.
The Democratic Republic of Congo produced 59% of the world’s cobalt. Other lithium-ion battery materials, such as nickel, have a more even distribution of production throughout the world.
