The Appalachian Mountains hold enough lithium to make 500 billion cellphones, researchers discover
Researchers from the U.S. Geological Survey have discovered that the Appalachian Mountains contain 2.5 million tons of lithium, enough to produce 500 billion cellphones. This significant reserve could reduce the U.S.'s reliance on lithium imports, which currently account for more than half of its usage. However, the environmental impact of mining these resources remains uncertain.
- ▪The Appalachian Mountains hold 2.5 million tons of lithium, sufficient for 500 billion cellphones.
- ▪Mining this lithium could decrease U.S. dependence on imports from countries like China and Argentina.
- ▪Currently, the U.S. has only one operational lithium mine in Clayton Valley, Nevada.
