A new lithium refinery in Robstown, Texas, is set to shake up how the world processes one of its most important battery materials. Tesla built the facility, and it began operations in January 2026, with full ramp-up ongoing.
It’s described as the largest and most advanced lithium refinery in the United States.
The refinery produces battery-grade lithium hydroxide, a key ingredient in electric vehicle batteries. It uses a clean, advanced process that’s unlike anything else currently running in North America. Tesla says the facility will help regionalize supply chains and cut emissions tied to long-distance mineral shipping.
China currently controls about 75% of the world’s lithium processing capacity. Australia, Chile, and China together account for 90% of global lithium production, but China refines most of it.
China controls 75% of global lithium processing, refining most of what Australia, Chile, and the world produces.
The country’s invested heavily over decades perfecting its refining chemistry. That dominance has made the U.S. heavily dependent on Chinese processing for critical battery minerals.
That dependence has become a growing concern. China recently placed export controls on battery materials like graphite amid rising trade tensions with the United States.
There’s also ongoing worry about forced child labor in mineral sourcing from Congo, where cobalt extraction in some Chinese supply chains has drawn scrutiny.
Texas’s refinery is part of a broader U.S. push to reduce that reliance. U.S. governments have invested in North American lithium producers, and multi-billion-dollar federal initiatives are already funding critical minerals extraction.
Officials have teased billions more in potential future support.
Texas isn’t stopping there. The Smackover Formation holds the most lithium-rich fluids in North America. Near Texarkana, TerraVolta is developing another refinery with reportedly federal backing.
The Round Top deposit also holds some of the richest heavy rare-earth minerals on the continent, targeting defense and semiconductor industries. Texas holds 15 of the 17 rare-earth minerals, with particular strength in the heavy rare-earths most critical to national security.
The U.S. currently has primarily one major operating lithium mine, located in Nevada, with a second planned for 2027. Building domestic refining capacity is seen as a critical step toward North American energy independence. Rather than releasing hazardous waste into the surrounding environment, the facility is designed to produce analcime for concrete, a reusable byproduct that replaces more harmful outputs common in traditional lithium refining.
Tesla’s Texas refinery is one of the first big moves in that direction.
