ExxonMobil Expands Into Synthetic Graphite with Acquisition
ExxonMobil, the global energy giant that has taken an interest in Arkansas lithium, is taking another step into the battery materials supply chain.
The company announced Sept. 8 plans to acquire the technology and U.S.-based assets of Superior Graphite, a century-old leader in the graphite industry. The deal includes select international offices and marks Exxon’s official entry into the synthetic graphite market, a key component for EV and energy storage batteries.
Why It Matters: Graphite is the largest single material in a lithium-ion battery, used in the anode. Synthetic graphite can be made with Exxon’s existing refining byproducts, offering higher consistency and performance than natural graphite. The company says its products could enable faster charging and longer-lasting batteries.
What They’re Saying:
In a news release, ExxonMobil said the acquisition will “build a robust, synthetic graphite supply chain — right here in the U.S.” and support American jobs.
Jesse Edmondson, the director of government relations for Arkansas DLE pioneer Standard Lithium Ltd., said of the announcement on LinkedIn: “Looks like things are heating up again for domestic battery materials. My phone has rang more in the last 30 days from folks looking for critical mineral projects in the U.S. than in all of the last year combined.”
The Bottom Line: ExxonMobil is already a player in South Arkansas through its Saltwerx LLC affiliate exploring lithium-rich brines in the Smackover Formation. By adding graphite, Exxon is building positions on both the cathode (lithium) and anode (graphite) sides of the battery supply chain.

ExxonMobil’s Saltwerx Test Drilling Lithium-Rich Brine in Columbia County
Speaking of ExxonMobil affiliate Saltwerx, that company has begun appraisal drilling southwest of Magnolia, the Magnolia Reporter reports:
The Hayden James 1 well will reach more than 10,000 feet into the Smackover Formation.
The project is focused on brine sampling to test for lithium content.
No commercial extraction will occur; the well will be plugged after testing.
Big Picture: If results confirm sufficient lithium, Saltwerx could seek a Brine Unit for large-scale production.
