Tesla's Texas lithium refinery is now operational, marking a significant milestone for the company's U.S. battery supply chain. The facility, located near Corpus Christi, is the first of its kind in North America, converting raw spodumene ore directly into battery-grade lithium hydroxide. This innovative process bypasses intermediate refining steps commonly used in the industry, making it both simpler and less expensive. Tesla staff explained that the facility processes spodumene through kilns and cooling systems, followed by alkaline leaching, purification, and crystallization, resulting in lithium hydroxide suitable for energy storage and electric vehicles. The process also eliminates hazardous byproducts, producing anhydrite, a co-product used in concrete mixes.
Elon Musk described the site as both the most advanced and the largest lithium refinery in the United States. The refinery's development timeline was impressive, with groundbreaking in 2023 and integrated plant startup in 2025, achieved through parallel feasibility studies, design, and construction. This compressed schedule enabled the fastest time-to-market for a refinery using this technology. By bringing large-scale lithium hydroxide production online in Texas, Tesla aims to reduce reliance on foreign refining capacity and support its growth in battery and vehicle production.
In other news, a Tesla arsonist who burned a Cybertruck in a politically motivated attack has been sentenced to five years in federal prison. The incident, which occurred in April 2025, destroyed a Tesla Cybertruck and endangered first responders, leading to mandatory sentencing under federal arson laws. The man, Ian William Moses, pleaded guilty to all five counts and was sentenced to 5 years in prison followed by 3 years of supervised release. The court also ordered him to pay restitution, which will be determined at a hearing in April 2026.
Additionally, Tesla's upcoming Optimus V3 robot has received early third-party feedback from angel investor Jason Calacanis. Calacanis visited Tesla's Optimus lab and shared his insights, stating that the robot will be so revolutionary that people will probably not even remember that Tesla used to make cars. He emphasized the potential transformative impact of Optimus, suggesting a 1:1 ratio of humans to robots. While Calacanis' comments were opinion-driven, they offer valuable insights into the robot's potential.
Finally, Tesla has tapped Samsung for 5G modems as it prepares to scale its autonomous driving and Robotaxi operations. Samsung's System LSI division has developed a dedicated automotive-grade 5G modem for Tesla, which is currently in the testing phase. Initial supply is expected to begin in the first half of 2026, with deployments planned for Tesla's Robotaxi fleet in Texas. This move signals Tesla's focus on supply-chain diversification and next-generation communications, as it aims to reduce reliance on Chinese and Taiwanese suppliers.
