Powering the U.S. Electric Vehicle Revolution
from Gaston County, North Carolina

The growing demand for electric vehicles is driving the future of America’s energy security. More electric vehicles on roadways means more lithium-ion batteries to power them. Today, China produces about 80% of the world’s battery-grade lithium – lithium hydroxide, while the United States only produces approximately 2% of the global supply.1

As America races to develop a robust, domestic battery supply chain, the team at Piedmont Lithium is charging ahead to become a leading producer of domestic lithium hydroxide. With a powerful purpose, we are working to develop our global lithium business to support the planet’s decarbonization, U.S. energy independence, and North Carolina’s growing electrification economy.

We’re proud to call Gaston County, North Carolina home to our corporate headquarters and proposed Carolina Lithium project. Through Carolina Lithium, we aim to significantly increase the current American production capacity of lithium hydroxide, while operating as one of the world’s most sustainable projects of its kind.

Carolina Lithium:
Our Proposed, Fully Integrated Operation

Carolina Lithium is being designed as one of the world’s only fully integrated lithium projects, with mining, spodumene concentrate production, and lithium hydroxide conversion happening all on one site.

The project is expected to produce 30,000 metric tons of battery grade lithium per year when fully operational. This production would more than double the current American production capacity of approximately 20,000 metric tons1 annually and greatly contribute to U.S. energy security.

Our expected annual production volume is enough to supply 600,000 electric vehicle batteries per year2 to help drive the electrification of transportation. 

In May 2024, we received the finalized mining permit for the construction, operation, and reclamation of Carolina Lithium following the posting of a $1 million reclamation bond to the state of North Carolina. Receipt of the mining permit is the precursor for the county rezoning process and a milestone that allows us to accelerate the funding process, which we expect will take some time to complete.

We are looking toward potentially commencing the local rezoning process in 2025, with the timing of the project’s development dependent upon our funding strategy, potential partnerships, and lithium market dynamics. Construction would follow, subject to obtaining the remaining necessary material permits, including our air and wastewater permits, as well as rezoning approvals and project financing activities.

Producing Lithium Hydroxide:

A Three-Step Process

At Carolina Lithium, we plan to produce lithium hydroxide through a three-step process that begins with mining the rock that contains lithium-bearing spodumene ore (lithium ore). The ore is then crushed and filtered to produce spodumene concentrate. We plan to convert the concentrate to lithium hydroxide with an innovative process that primarily uses steam and pressure to produce lithium hydroxide, a non-flammable, salt-like compound, for EV and battery manufacturers.
