What is Lithium Triangle?

The Lithium Triangle is a region of the Andes rich in lithium reserves around the borders of Argentina, Bolivia and Chile. The lithium in the triangle is concentrated in various salt pans that exist along the Atacama Desert and neighboring arid areas, the largest ones including Salar de Uyuni in Bolivia, Salar de Atacama in Chile and Salar del Hombre Muerto in Argentina.

The area is thought to hold around 54% of the world's lithium reserves. The Indian Navy has shown interest in the Lithium Triangle as lithium will be required on Li-ION batteries that are planned to be fitted in future submarines.
