GM and Cirba Turn Recycled Metal Into Finished Battery Cells

Cirba Solutions and GM completed a closed-loop EV battery recycling pilot in which new battery cells were built using 100% recycled critical minerals.

Cirba Solutions and GM have finished a closed-loop pilot for electric-vehicle battery recycling, producing new battery cells made with 100% recycled critical minerals. The distinction matters: this was not a demonstration of collecting and shredding old packs, which the industry has done at scale for years. It was a demonstration that the metal recovered at the end of that process can go back into a cell without a fresh molecule of mined nickel, cobalt, manganese or lithium in the active material.

That is the definition of "closed loop" that the battery supply chain has been chasing. Material leaves a vehicle, is processed domestically, and returns as cathode-grade input. Every step between those two points has, until recently, been the weak link in North America.

Why recovered cathode metal is worth more than recovered mass

Battery recycling economics are not about tonnage. They are about which elements survive the process in a form a cell maker will accept. Shred a pack and you get a mixed powder, often called black mass, containing nickel, cobalt, manganese, lithium and a great deal of contamination — copper, aluminum, plastics, electrolyte residue. Selling black mass is a commodity business with thin margins and, historically, an export business, because much of the refining capacity that turns it into battery-grade salts sits in Asia.

Producing cell-ready material domestically is a different proposition. It captures the refining step, which is where the value concentrates, and it produces a material with a documented chain of custody. For an automaker, that documentation is not a nicety. Sourcing rules attached to US clean-vehicle incentives turn on where critical minerals are extracted, processed or recycled, and material recycled in North America is treated favorably. A recycled-content pathway that can be evidenced cell-by-cell is therefore a compliance asset as much as a procurement one.

The pilot, reported by Innovation News Network, establishes technical feasibility rather than commercial volume. No production figures were attached to it. But feasibility is the gate that had to be cleared first, because cell manufacturers are conservative buyers: impurity tolerances in cathode precursor are measured in parts per million, and a recycled input that cannot hit those specs consistently is not an input at all.

What a working loop does to GM's mineral exposure

An automaker buying nickel and cobalt is exposed to three things it cannot control: the price of the metal, the jurisdiction it comes from, and the shipping and tariff regime between the two. Recycled feedstock does not eliminate price exposure — recovered nickel is still priced off the same benchmarks — but it changes the other two materially. Feedstock that originates as end-of-life packs, warranty returns and manufacturing scrap from domestic plants is a supply source that sits inside the same borders as the cell plants consuming it.

Manufacturing scrap is the underrated part. A new cell plant ramping toward full yield generates substantial off-spec material, and that scrap is chemically pristine compared with a decade-old pack pulled from a crashed vehicle. It is the cleanest recycled feedstock available and it arrives on a predictable schedule tied to production, not to the retirement curve of vehicles sold years ago. In the early years of any closed-loop system, scrap does the heavy lifting; end-of-life packs become the dominant stream only as the installed fleet ages.

That sequencing is why closed-loop announcements tend to come from automakers with large domestic cell footprints. The loop needs both ends — a processor with hydrometallurgical capacity and a cell maker producing enough volume to supply and absorb the material — physically close enough that freight does not eat the margin.

The market reaction and what it does not tell you

GM shares last traded at 82.63, up 2.56% on the day, against a previous close of 80.57 and a session range of 80.88 to 83.50, as of the close on Friday, 25 September 2026. The broader market was firmer the same session: the S&P 500 tracker closed at $771.35, up 0.54%, the Nasdaq 100 proxy at $744.50, up 0.46%, and the Dow tracker at $517.49, up 0.94%.

No one should read a single day's move as a verdict on a recycling pilot. A pilot with no disclosed volumes, no stated capital commitment and no timetable to commercial output does not move a company of GM's size. What the price action does establish is context — the stock outperformed all three major benchmarks that session, in a market that was broadly higher.

The figure investors will eventually want is different: how many gigawatt-hours of cell production can be fed with recycled cathode material, at what cost relative to purchased virgin salts, and on what date. None of those numbers exists publicly yet.

What has to happen next for this to matter commercially

Three things separate a successful pilot from a supply chain.

• Qualification at volume. A cell built from recycled material has to pass the same cycle-life, safety and calendar-aging testing as any other cell, repeatedly, from multiple production lots. Pilots prove chemistry; qualification proves consistency.
• Committed feedstock. Recyclers compete hard for scrap and end-of-life packs. A closed loop only closes if the processor has contracted access to a specific automaker's returns rather than bidding for material on an open market alongside everyone else.
• Refining capacity on the ground. Turning black mass into battery-grade nickel and cobalt sulphate and lithium compounds requires hydrometallurgical plants that take years and substantial capital to build. Domestic capacity, not chemistry, is the binding constraint on how much recycled mineral the US can actually supply.

The wider read for battery metals

Every unit of recycled cathode material that reaches a cell plant is a unit of mined concentrate that does not need to be imported, refined offshore and shipped back. In the near term the displacement is small — the recycled stream is a fraction of what new cell capacity consumes. Over a full vehicle-fleet cycle, it becomes a structural second source, and one with a cost curve that behaves differently from mining: no ore grade decline, no permitting timeline, no stripping ratio. The cost driver is collection logistics and process yield.

For miners, this is not an immediate demand threat; battery demand growth still outruns what recycling can return. But it does put a ceiling on how far Western buyers can be squeezed on jurisdictional risk premiums, because a domestic alternative now exists in demonstrated form rather than as a slide in a strategy deck. That is the quiet significance of a pilot that produced actual cells rather than a specification sheet.

Frequently asked questions

What does "closed-loop" battery recycling actually mean?

Closed-loop means material recovered from used or scrap batteries is processed and returned into the manufacture of new battery cells, rather than being sold into other industries or exported as unrefined intermediate. In the Cirba Solutions and GM pilot, the new cells were made with 100% recycled critical minerals, meaning the cathode input came entirely from recovered material.

Which minerals are recovered from EV batteries?

The commercially valuable elements in a lithium-ion cathode are nickel, cobalt, manganese and lithium. Copper and aluminum from current collectors and casings are also recovered. Nickel and cobalt typically carry the most value, which is why recycling economics have historically depended on high-nickel, cobalt-containing chemistries rather than lower-value cathode types.

Does this pilot mean GM stops buying mined minerals?

No. A pilot demonstrates technical feasibility, not volume. The recycled stream available today is a fraction of what new cell capacity consumes, so mined and refined virgin material remains the dominant input. Recycling becomes a meaningful second source only as manufacturing scrap volumes rise and the installed vehicle fleet begins retiring in quantity.

What is black mass and why does refining capacity matter?

Black mass is the mixed metal powder produced when battery cells are shredded. It contains nickel, cobalt, manganese and lithium along with contaminants. Turning it into battery-grade chemical salts requires hydrometallurgical refining, capacity that has historically been concentrated in Asia. Domestic refining is the step that keeps value and supply-chain control in North America.

How did GM shares trade around the announcement?

GM last traded at 82.63, up 2.56% on the day from a previous close of 80.57, with a session range of 80.88 to 83.50, as of the close on 25 September 2026. That outpaced the major benchmarks the same session, though a pilot with no disclosed volumes or capital figures is not on its own a driver of a move that size.

Why is recycled content relevant to US clean-vehicle incentives?

US clean-vehicle tax credit rules condition eligibility partly on where critical minerals are extracted, processed or recycled. Material recycled within North America is treated favorably under those sourcing tests. A documented closed-loop pathway therefore serves a compliance purpose for an automaker as well as a procurement and supply-security purpose.
