Where Does Lithium Come From?

Lithium ion batteries will be used in many of the upcoming plug-in hybrid vehicles and electric vehicles because they are lighter and more powerful than the nickel-metal hydride batteries used in current hybrid vehicles. Global lithium production reached 22,800 tons in 2008. Lithium reserves are a topic of debate, with estimates ranging from 4 million tons to 20 million tons. The latest data show that Chile has the largest share of lithium production, while Bolivia has the largest reserves. The U.S. is responsible for less than 10% of lithium production.
