ExxonMobil drills first Arkansas lithium well, targeting EV supply by 2030

ExxonMobil has begun drilling its first lithium well in Arkansas's Smackover formation, aiming to become a leading EV battery supplier by 2030 using direct lithium extraction. The entry of a major oil company into low-emission lithium production signals diversifying global battery-material sources relevant to India's import-dependent EV sector.

ExxonMobil is initiating drilling of its first lithium well in southern Arkansas to supply Mobil Lithium for EV batteries. In early 2023 the company acquired rights to 120,000 gross acres of the Smackover formation, considered one of North America's most prolific lithium resources of its type. ExxonMobil uses traditional drilling to extract lithium-rich saltwater, then applies direct lithium extraction (DLE) to separate lithium, converting it onsite to battery-grade material and re-injecting remaining saltwater. DLE produces fewer carbon emissions than hard-rock mining and requires significantly less land.

The development affects electric vehicle and battery manufacturers, with whom ExxonMobil is actively engaging as potential customers, and the broader North American lithium supply chain. Arkansas, historically an oil and natural gas state, stands to become a significant player in the emerging lithium industry. The move emphasises domestic sourcing for energy security while minimising environmental impact, positioning ExxonMobil to expand lithium production globally and supply enough lithium by 2030 to meet the demands of more than a million electric vehicles annually.

ExxonMobil targets the start of production by 2027, with a 2030 goal of supplying over a million EVs annually. Industry participants and customers should monitor the company's customer agreements with EV and battery manufacturers as it works to solidify its supplier role. Stakeholders should also track the scale-up of DLE technology as a lower-impact alternative to traditional mining, and ExxonMobil's stated vision to expand lithium production globally beyond the initial Arkansas project.
