A recent invention by ExxonMobil could significantly change the electric vehicle battery game: a new kind of graphite (Bloomberg, subscription).

What’s going on: “We’ve invented a new carbon molecule that will extend the life of the battery by 30%,” Chairman and CEO Darren Woods said at the University of Texas at Austin’s Energy Symposium last Friday. He added that it’s a “revolutionary step change in battery performance.”

• Graphite plays a critical role in lithium-ion EV batteries, which the energy giant invented in the 1970s. The crystalline form of carbon helps lithium, a crucial battery component, maintain structural integrity and ensures that the batteries remain stable during charging and discharging cycles.
• ExxonMobil announced last week that it had acquired “key assets and technology” from Chicago-based graphite firm Superior Graphite to “complement [its] planned entry into the battery anode graphite market.”

Why it’s important: “Used on the anode side of the battery, the synthetic graphite allows for faster charging, a longer lifespan and longer range for electric vehicles.”

What’s next: While ExxonMobil isn’t planning to go into EV battery production, it says it will use its refineries, laboratories and plants to manufacture some of the materials for batteries—and begin extracting lithium, too.

• “[W]e do have capability of transforming molecules, and there are enormous opportunities in that space to use hydrogen and carbon molecules to meet the growing demand,” Woods said.
