This comes at a time when global demand for lithium, driven by electric vehicles and energy-storage needs, continues to grow. In 2023, global lithium consumption reached 180,000 metric tons, up from 142,000 metric tons in 2022, according to the United States Geological Survey. But the U.S. produces less than 1% of the world's supply.

While most of the world's lithium still comes from countries like Australia, Chile and China, Arkansas could change that.
