The new Tesla batteries use very little cobalt. Of course this has been going on for years but it only concerns you when EV's are involved.
Cobalt is a common by-product of iron mining ... what fncceo is referencing is the Lanthanide and Actinide metals ... the mining of which involves child slaves in impoverished third-world countries ... along the lines of "blood diamonds" ... I don't know how much of these types of materials are used in EV's, I thought the major market was for these new fangled telephones ...
EV's do use a lot of Lithium, and that's not particularly abundant ... the Antiplano is a major source with relatively higher social standards for employees ...
