The settlement of Uis in a remote part of Namibia seems an unlikely hotspot for a mineral cold war over the future of electric vehicles.
Uis lies in the arid hills of Erongo, a large and sparsely populated province of the west African country. For decades the only signs of its mineral wealth were the gemstones sold to tourists by artisanal miners, who scrabbled a living in the shadow of a disused tin mine.
But soon the site of that mine will be part of a global race for lithium, the alkali metal that is a key raw material for automotive batteries. Securing reliable lithium supply is one of the biggest challenges facing carmakers striving to produce more electric vehicles.
