Arcam · Premium LFP cathode

The long road to producing LFP in the U.S. just got a lot shorter.

We make premium cathode material by mining yesterday’s spent cells, not waiting for tomorrow’s new mines. Already proven at the Gigascale.

The process

The shortest path from spent cell to cathode.

Conventional LFP cathode is mined, refined, and synthesized across a complex, foreign supply chain before it ever reaches a cell manufacturer. Arcam’s ReCAM™ process skips all of it, regenerating premium CAM directly from spent cells. And we’re bringing that production to American soil.

The Arcam route
The Arcam closed loop Spent LFP cells supply black mass to Arcam’s ReCAM™ process, which regenerates it into premium LFP cathode active material. That cathode goes into new LFP cells, which are used and eventually retired, returning to the start of the loop. feedstockregeneratebuild cellsuse & retire CLOSED LOOP cell to cell Spent LFP cellsblack mass Arcam ReCAM™regeneration Premium LFP CAMGen 3 · Gen 4 · Gen 5 New LFP cellsEV · ESS

The product

Retired cells in. Premium cathode material out.

A true drop-in replacement for LFP cell manufacturers that meets or exceeds the performance of ‘new’ cathode material. Commercialized across grades for every LFP application.

Why Arcam

The best and fastest path to onshore LFP cathode material production.

Built for American supply
We’re bringing ReCAM™ production to the U.S. to give North American cell makers a domestic source of LFP cathode that doesn’t depend on foreign mining, refining, or precursors. U.S.-made material can support domestic-content requirements and Section 45X manufacturing credits, subject to Treasury rules.
We skip the mine
No extraction, mining, refining, or precursor synthesis. By preserving the LFP crystal structure through regeneration, we skip four supply chain steps and get to battery-grade material in a fraction of the time.
Sustainable and cost-efficient
A lighter footprint than conventional cathode material production; no strong acids, no sodium sulfate waste, lower carbon emissions, and no additional external precursors are needed.
Proven at the Gigascale
This isn’t a pilot. With 1.8 GWh running commercially and 6.8 GWh under construction, Arcam’s process is proven at scale and ready to be replicated on American soil.

Company & technology

What is Arcam?

Arcam is a battery materials company that makes lithium iron phosphate (LFP) cathode active material (CAM) directly from spent LFP batteries. Founded at MIT in 2021 and headquartered in Hopkinton, Massachusetts, Arcam uses its proprietary ReCAM™ regeneration process, which already runs at commercial gigawatt-hour scale.

What is LFP cathode active material?

LFP cathode active material is the lithium iron phosphate (LiFePO₄) powder in the positive electrode of an LFP battery, where lithium ions are stored and released during charge and discharge. LFP is widely used in electric vehicles and stationary energy storage because it is safe, long-lived, and contains no nickel or cobalt.

What is the ReCAM™ process?

ReCAM™ is Arcam’s proprietary process for regenerating the cathode in spent LFP batteries into battery-grade LFP cathode active material. Instead of breaking the cathode down into its elements, ReCAM™ preserves the olivine LFP crystal structure and restores it to specification, producing high-density cathode ready for new cells.

How is ReCAM™ different from conventional battery recycling?

Conventional hydrometallurgical recycling dissolves spent cathode in strong acids to recover lithium salts, which must then be refined and re-synthesized into new cathode. Arcam’s ReCAM™ process keeps the LFP crystal structure intact, so it skips extraction, mining, refining, and precursor synthesis, uses no strong acids, and generates no sodium sulfate waste.

What feedstock does Arcam use?

Arcam’s feedstock is black mass recovered from end-of-life LFP batteries and from LFP battery production scrap. Because ReCAM™ is built specifically for LFP chemistry, the cathode in that black mass is regenerated directly into new cathode active material rather than reduced to raw materials.

Product & qualification

What LFP cathode grades does Arcam offer?

Arcam offers three grades of LFP cathode active material. Gen 3 ESS Grade serves stationary and grid energy storage. Gen 4 EV Grade offers EV-grade compaction density for passenger and fleet vehicles. Both are commercialized. Gen 5 is an ultra-high compaction density grade for premium EVs, proven at lab scale and now at pilot stage.

Does regenerated LFP cathode perform as well as new material?

Yes. Arcam’s regenerated LFP cathode is a drop-in replacement that meets or exceeds the performance of cathode made from newly mined and refined materials. Specification documents for each grade are available on request for cell manufacturers evaluating the material.

How can a cell manufacturer qualify Arcam’s cathode material?

Cell manufacturers can start qualification by requesting the Gen 3 or Gen 4 specification document on this page, or by contacting Arcam at contact@arcam.tech to discuss samples, application requirements, and timelines.

Scale & supply chain

How much LFP cathode does Arcam produce?

Arcam’s ReCAM™ process runs at commercial scale with 1.8 GWh of annual production capacity, about 4,000 tonnes of cathode per year. Arcam is scaling that capacity to 6.8 GWh, about 15,000 tonnes per year, by Q4 2026.

Where is Arcam’s cathode material made?

Arcam’s current commercial production runs in Asia. In addition to its pilot line and R&D headquarters in Hopkinton, Massachusetts, Arcam is bringing the ReCAM™ process to the United States with a planned commercial plant to supply North American cell manufacturers.

How does Arcam support a domestic U.S. LFP supply chain?

LFP cathode supply is concentrated overseas, largely in China. Arcam’s ReCAM™ process makes cathode from batteries already in circulation, so U.S. production does not depend on new mines, refineries, or imported precursors. That shortens the path to domestic LFP cathode for North American cell manufacturers and energy storage developers.

Can U.S.-made Arcam cathode qualify for Section 45X or domestic-content credits?

Cathode active material produced in the United States can qualify for the Section 45X advanced manufacturing production credit and can support domestic-content requirements for energy storage projects, subject to current Treasury rules, including prohibited foreign entity restrictions. Arcam’s planned U.S. production is being designed with these requirements in mind; eligibility depends on the facts of each project.

Is ReCAM™ more sustainable than conventional cathode production?

Yes. ReCAM™ has a lighter footprint than conventional LFP cathode production because it avoids mining and refining, uses no strong acids, produces no sodium sulfate waste, needs no additional external precursors, and results in lower carbon emissions.

For black mass suppliers

Does Arcam handle LFP black mass?

Yes. Arcam handles lithium iron phosphate (LiFePO₄) black mass from battery recyclers, cell manufacturers, and collectors as feedstock for its ReCAM™ regeneration process, including black mass from end-of-life LFP batteries and LFP production scrap. Suppliers can reach Arcam through the supplier form on this page.

What black mass specification does Arcam require?

Arcam requires LFP black mass that meets defined limits on chemical composition, moisture, particle size, and magnetic and trace-metal contamination. Arcam shares its full black mass specification with prospective suppliers on request.

How does Arcam qualify a black mass supplier?

Arcam qualifies black mass suppliers in two stages. First, Arcam tests a sample of the supplier’s material against its specification at its existing production facility, which typically takes four to eight weeks. Suppliers whose material qualifies then move toward long-term offtake agreements for Arcam’s planned U.S. facility.

How can a black mass supplier contact Arcam?

Black mass suppliers can use the supplier form on this page or email contact@arcam.tech. Include your company, location, typical monthly volume, and material source, such as end-of-life batteries or production scrap, and Arcam will follow up with its specification and sampling instructions.
