Quick Takeaways
- Tesla lithium hydroxide refinery brings North America closer to domestic battery-grade lithium supply.
- The new Tesla facility in Corpus Christi is now producing lithium hydroxide for electric vehicle batteries.
On 15 January 2026 Tesla has released a new video offering a detailed look inside its large-scale lithium refining plant in Corpus Christi, Texas, while confirming that the Tesla lithium hydroxide refinery has officially begun production.
The new facility represents a major step in Tesla’s strategy to strengthen its battery supply chain. For years, CEO Elon Musk has stressed that while lithium resources are widely available, the ability to refine them into battery-grade lithium hydroxide remains one of the biggest constraints in electric vehicle manufacturing.
Why the Tesla lithium hydroxide refinery matters
The Tesla lithium hydroxide refinery was built to address one of the most critical bottlenecks in the EV industry: limited refining capacity. Lithium ore is relatively abundant, but converting it into high-purity lithium hydroxide requires advanced processing that few facilities in North America can perform at scale.
To overcome this challenge, Tesla decided to vertically integrate lithium refining into its operations. Construction of the refinery began in Robstown, near Corpus Christi, in 2023, with the goal of deploying a faster, more cost-efficient refining process that supports long-term battery production.

The newly released video features Jason Bevan, Tesla’s Site Manager for the project, who walks through the now-operational plant. According to Bevan, the facility is the first of its kind in the region to process spodumene into battery-grade lithium hydroxide, a key material used in high-energy-density EV batteries.
Key highlights of the refinery include:
This makes the plant a critical link between raw lithium sources and Tesla’s battery manufacturing operations.
Strengthening North America’s battery supply chain
By bringing lithium refining in-house, Tesla is reducing dependence on overseas processing, particularly from Asia, where most battery-grade lithium is currently refined. The Tesla lithium hydroxide refinery is designed to improve supply security, shorten logistics chains, and lower long-term battery material costs.
With the facility now producing material, Tesla is positioning itself to better support the rapid growth of its electric vehicle and energy storage businesses. The move also supports the broader push to localize battery supply chains across North America as EV demand continues to rise.
As Tesla continues to expand battery production, the Corpus Christi refinery is expected to play a central role in ensuring consistent access to high-quality lithium hydroxide for next-generation electric vehicles.

- Direct conversion of spodumene into lithium hydroxide
- Location close to major U.S. ports and logistics hubs
- Integration into Tesla’s broader battery supply network
