Graphite One plans $80m Ohio anode plant ahead of Alaska mine

By Amara Osei

Graphite One is targeting an April 2027 final investment decision on an $80 million Conneaut, Ohio, plant with planned annual capacity of 10,000 metric tons of anode material. The first phase would blend and coat purchased synthetic graphite for lithium-ion batteries used in electric vehicles and energy storage, with first sales targeted for the fourth quarter of 2028.

The Ohio phase does not depend on ore from Graphite Creek in Alaska, which still has no production date. The $80 million estimate remains provisional; Graphite One expects to revise it after final engineering.

Graphite One announced a final Ohio Environmental Protection Agency air permit on Nov. 2. Other state and local approvals, project financing and final engineering remain ahead. The company cautions that the plant may not be built.

What does this change for battery buyers?

Battery buyers would gain a potential onshore coating source before domestic ore supply arrives. The 10,000-ton first line is twice the 5,000 metric tons annually contemplated in Graphite One’s nonbinding Lucid agreement, but capacity is not a contract, and a contract is not a qualification.

Qualifying a new supplier in these capital-heavy categories can take six to 18 months, so a late-2028 production start would not guarantee immediate cell-maker deliveries. Graphite One has sent samples to prospective U.S. battery and energy-storage customers for testing and qualification.

Its best-known buyer link is a nonbinding agreement with Lucid, announced in July 2024, for 5,000 metric tons a year of synthetic anode material over an initial five-year term once production begins. The company says binding agreements with Lucid have not been signed.

Chief Executive Anthony Huston said: “Ohio lets the company pursue customer revenue before mine production begins.” That is the commercial logic: convert purchased feedstock into customer revenue while the mine waits. The separation reduces the Ohio project’s dependence on Graphite Creek, but leaves it exposed to supplier availability and qualification.

The sourcing backdrop remains import-heavy. According to the U.S. Geological Survey, the U.S. mined no natural graphite in 2025 and remained fully import-reliant. Imports of battery anode material that year came mainly from China, at 55%, followed by Indonesia and South Korea.

China’s pause on export controls covering graphite anode material was set to end Nov. 10 under its published legal text, adding another variable for buyers weighing feedstock origins. Graphite One has not named its synthetic graphite supplier, and its Ohio plan moves the coating step onshore rather than the mining step. Mine-stage projects such as Westwater Resources’ Coosa project in Alabama target the same import gap from the ore side.

For shippers, carriers and forwarders, no transport lane, cargo schedule or contracted tonnage has been disclosed. With the feedstock supplier unnamed, planners cannot yet build a reliable freight forecast from the announcement. The commercial signal is a prospective demand pool, not booked cargo.

EXIM issued an amended $1.4 billion letter of interest in December 2025 for expansion of the Ohio plant in 25,000-ton steps to 100,000 metric tons a year, ten times the initial nameplate. A separate $670 million letter covers Graphite Creek.

Neither letter commits money: both remain subject to an application, due diligence and credit approval. The distinction is doing a lot of work; the $1.4 billion indication supports a larger future buildout, not the $80 million first phase or guaranteed output. The $670 million letter for Graphite Creek does not resolve the Alaska schedule, where the project still has no production date.

April’s investment decision on the first 10,000 tons is the next marker, Graphite One said. The decision follows the cost-estimate revision, remaining permits, project financing and final engineering; failure would leave the Conneaut schedule and EXIM expansion at the proposal stage.

Qualification remains another gate, and the company cautions that testing may not succeed. Even a successful construction decision would not make the plant an approved source for every cell maker. Samples, testing, binding purchases and operating performance still sit between announcement and revenue.

The next capacity milestone is April 2027, not the 100,000-ton vision. Before then, China’s Nov. 10 export-control transition and the unnamed feedstock supplier remain the practical sourcing variables.
