Lithium
ExxonMobil has a long history of developing innovative products for the auto industry – from fuels to lubes to advanced plastics. Now we’re adding a new one: lithium.
What is lithium? It's a key component of electric vehicle batteries. To meet projected growth in EVs, the world will need a lot more lithium. ExxonMobil plans to become a leading supplier of lithium, using a modern process that has significantly less environmental impact than traditional mining.
We also have a deep connection to battery technology: Our own Dr. M. Stanley Whittingham led the research that resulted in the world’s first lithium-ion battery. In 2019, he won a Nobel Prize for his work. Read about the battery that changed the world.
Lithium is the latest example of how we’re helping automakers meet the world’s evolving transportation needs while also working to reduce emissions.

LG Chem and ExxonMobil sign MOU for lithium offtake
LG Chem would use up to 100,000 metric tons at its new cathode plant in Tennessee; it's our second lithium customer MOU.
Making history: Lithium and a Nobel Laureate
We don’t often get to meet our heroes in person, but our very own Patrick Howarth did.
Patrick leads our new lithium business – and he recently met Dr. Stanley Whittingham, whose groundbreaking research in an ExxonMobil lab in the 1970s earned him a Nobel Prize in Chemistry. That research also paved the way for the lithium-ion batteries that power today’s electric vehicles and portable electronics.
Arkansas, United States
Southwest Arkansas has a long history as an oil and gas producer. But deep underground is another valuable resource: saltwater brine, rich in lithium. We can safely produce this lithium using many of the skills we’ve honed over decades, including geoscience, reservoir engineering and chemical processing.
Our lithium will strengthen supply security for the companies investing in EV and battery manufacturing facilities in North America.
The product will be branded as Mobil™ Lithium, building on the rich history of deep technical partnership between Mobil and the automotive industry.

Why it matters
-
Critical shift
EVs can play a key role in reducing emissions in transportation, which today accounts for nearly one-quarter of global energy-related CO2 emissions. -
New supply source
Today, most of the world’s lithium is produced in Western Australia, South America and China. We plan to produce lithium in North America. -
In demand
EVs rely on lithium for their rechargeable batteries. Lithium demand is expected to quadruple by 2030. -
Competitive edge
We’ll tap lithium-rich brines deep underground, using processes similar to those we use in our existing production and refining businesses.
A three-step process
- We’ll extract lithium-rich brine from rock formations deep underground (~10,000 feet). Brine is salty water unsuitable for drinking or agriculture.
- Above ground, we’ll use a process called Direct Lithium Extraction (DLE) to extract lithium from the brine quickly and efficiently.
- We’ll pump the leftover brine back underground, into the same reservoirs it came from.
This safe process is similar to many of the technologies we use today in our existing businesses.
Our lithium impact
90 %
When using electricity from a renewable source, EVs can reduce lifecycle CO2 emissions by nearly 90% vs. conventional vehicles.
2/3 less
Our lithium is expected to have ~2/3 less carbon intensity than hard-rock mining.
1 million
By the first half of the 2030s, we aim to produce enough lithium to supply the manufacturing needs of about 1 million EVs a year.
Low Carbon Solutions
Low Carbon Solutions is helping to lower emissions by providing solutions to our industrial and commercial customers in growing markets for carbon capture and storage, hydrogen and lower emission fuels.
