8 critical US battery metal projects to watch in 2026
In 2026, the global race to secure battery metals has reached a fever pitch, driven by a structural shift in how the world moves and stores energy. For the United States, the stakes are particularly high as the requirement for critical minerals in electric vehicle batteries to be extracted or processed domestically or by free trade partners rises to 80 percent by the end of this year. This regulatory pressure, combined with the launch of Project Vault, a 12 billion dollar strategic mineral reserve designed to establish a price floor for domestic supply, has turned the spotlight on a handful of high impact mining and processing assets.
The following eight projects represent the vanguard of this domestic movement. From the sagebrush of Nevada to the historic mining districts of Idaho and Minnesota, these operations are hitting critical milestones in 2026 that will determine the resilience of the American battery supply chain for decades to come.
Lithium America’s thacker pass project in Nevada
The Thacker Pass project remains the most significant lithium development in the United States, and 2026 is the year it moves into the final stages of mechanical completion. Located in the McDermitt Caldera in northern Nevada, this sedimentary based deposit is expected to supply up to 25 percent of total US lithium demand at full capacity. The project has benefited from massive federal support, including a 2.26 billion dollar loan from the Department of Energy and a strategic investment from General Motors.
As of early 2026, the focus at Thacker Pass has shifted from site preparation to the integration of advanced mineral extraction and processing technologies. The project is designed to produce battery grade lithium carbonate directly on site, which is essential for meeting the strict sourcing requirements of the Inflation Reduction Act. Beyond its industrial scale, the project is being watched as a test case for sustainable mining in semi arid regions, with a design that prioritizes water recycling and minimizes land disturbance through a co-disposal method for tailings.
South32 hermosa project in Arizona
While often discussed for its zinc and silver potential, the Hermosa project in southern Arizona has emerged as a critical source of battery grade manganese. In early 2026, the project received a major boost with the negotiation of a 166 million dollar grant from the Department of Energy to support a state of the art manganese production facility. This would make Hermosa the only fully integrated source of high purity manganese monohydrate in North America, a vital component for several electric vehicle battery chemistries.
South32 is currently advancing the construction of the Taylor zinc lead silver deposit while simultaneously fast tracking the Clark manganese deposit. The company aims to use Hermosa as a blueprint for modern, low carbon mining, employing automation and renewable energy integration to reduce its environmental footprint. With manganese supply currently dominated by overseas markets, the progress at Hermosa throughout 2026 will be a key indicator of U.S. success in diversifying its critical mineral portfolio.
Ioneer Rhyolite Ridge Project in Nevada
Rhyolite Ridge is a unique asset because it is the only known lithium boron deposit in North America. Following the withdrawal of a previous partner in 2025, ioneer is expected to finalize a new strategic partnership in the first half of 2026 to push the project through construction. The project is already shovel ready, having secured a 996 million dollar federal loan and all necessary environmental permits.
The co-product economics of Rhyolite Ridge are particularly compelling. Boron is an essential element for energy efficient glass and advanced electronics, and its production alongside lithium allows the project to operate in the lowest cost quartile globally. By 2026, the company expects to reach full commercial production readiness, with the capacity to supply enough lithium for over 370,000 electric vehicles annually. Investors and policymakers are watching ioneer closely this year to see how the new joint venture structure will accelerate the delivery of these critical materials.
Perfection of the Stibnite gold project in Idaho
The Stibnite Gold Project, managed by Perpetua Resources, is gaining international attention not just for its gold but for its massive antimony reserves. Antimony is a federally designated critical mineral essential for high capacity liquid metal batteries and national defense applications. With China tightening export controls on antimony in early 2026, the Stibnite project has become a strategic priority for the United States.
The project is unique in its focus on environmental restoration. The mine plan includes the rehabilitation of a historic mining district, including the restoration of over 30 miles of rivers and the removal of legacy tailings. In 2026, the project is moving through the final phases of permitting and project financing, buoyed by its inclusion in the fast track list of priority mineral projects. Its success would provide the U.S. with its only domestic source of antimony, significantly reducing reliance on foreign imports.
Talon Metals tamarack nickel project in Minnesota
Located in central Minnesota, the Tamarack project is a high grade nickel copper cobalt deposit being developed in a joint venture with Rio Tinto. In early 2026, Talon Metals reached a pivotal milestone by aligning its feasibility study with the publication of the Scoping Environmental Assessment Worksheet. This synchronization ensures that the mine’s design incorporates public and regulatory feedback from the outset, a strategy Talon calls a symphony of environmental review and exploration.
Nickel is a cornerstone of long range electric vehicle batteries, and Tamarack is one of the few domestic projects capable of producing the high purity nickel required by manufacturers like Tesla, which has already signed an offtake agreement with the project. Throughout 2026, Talon is also expanding its footprint by integrating the recently acquired Eagle Mine and Humboldt Mill operations, creating a multi asset nickel company that could anchor the Midwest’s growing battery belt.
Titan Mining Empire State Mines graphite project in New York
While Empire State Mines has long been known for record breaking zinc production, 2026 marks its debut as the first end to end natural flake graphite producer in the United States in over 70 years. The Kilbourne graphite facility commenced production of concentrate in January 2026, serving as a critical platform for customer qualification and product testing.
Graphite is the primary material used in the anodes of lithium ion batteries, and the U.S. is currently almost entirely dependent on imports for this material. The imposition of steep anti-dumping duties on Chinese graphite imports in early 2026 has significantly enhanced the competitive position of Titan Mining. The company is currently optimizing the Kilbourne facility with plans to ramp up capacity as it secures long term offtake agreements with domestic battery manufacturers.
Controlled thermal resources Hells Kitchen project in California
Deep beneath the Salton Sea in California lies a massive geothermal resource that contains some of the world’s richest lithium brines. Controlled Thermal Resources is developing the Hell’s Kitchen project to extract lithium using geothermal power, resulting in a nearly zero carbon footprint. In 2026, the project is moving into a critical scale up phase, aiming to demonstrate that it can produce battery grade lithium hydroxide at commercial volumes.
The project is a centerpiece of what has been dubbed Lithium Valley. Unlike traditional open pit mines, the geothermal extraction process used at Hell’s Kitchen has a very small surface footprint and provides a continuous, reliable source of renewable energy to the grid. As the U.S. pushes for more sustainable sourcing, the milestones achieved at Hell’s Kitchen this year will serve as a litmus test for the viability of geothermal lithium extraction on a global scale.
Ford SK on Blueoval SK Battery Park in Kentucky
While the previous items on this list focus on extraction, the BlueOval SK Battery Park in Kentucky is where those raw materials are transformed into power. In 2026, this massive 5.8 billion dollar joint venture between Ford and SK On is entering its primary commissioning phase. The site features twin gigafactories designed to produce over 80 gigawatt hours of battery cells annually, enough to power hundreds of thousands of next generation Ford and Lincoln electric vehicles.
The Kentucky project is part of a broader trend of onshoring battery manufacturing to the American South and Midwest. Throughout 2026, the facility will be a major driver of regional employment and a key consumer of the lithium, nickel, and manganese produced by the mining projects listed above. The successful ramp up of BlueOval SK is essential for Ford’s goal of making electric vehicles more accessible and affordable for the mass market.
