Recycled Battery Material (Closed-Loop Cathode and Copper Foil) Market

The global recycled battery material market size was USD 0.57 Billion in 2025 and is expected to register a revenue CAGR of 22.2% during the forecast period. Market revenue growth is supported by Redwood Materials, which processed more than 20 gigawatt-hours of lithium-ion batteries in 2024, enough material for roughly 250,000 electric vehicles, while recovering more than 95 percent of the critical minerals inside at its Nevada and South Carolina campuses, and which is ramping anode copper foil production toward a targeted 100 gigawatt-hours, or 250,000 kilometres, of annual output. Toyota's agreement to source cathode active material and copper foil from Redwood, targeting a minimum of 20 percent recycled nickel, 20 percent recycled lithium and 50 percent recycled cobalt in its cathode and 100 percent recycled copper in its anode copper foil, is among the most specific disclosed closed-loop content commitments in the industry. American Battery Technology Company reported a 64 percent quarter-over-quarter revenue increase and its first-ever positive gross margin in the third quarter of its fiscal year 2026, ended March 31, 2026, driven by ramp-up at its Nevada critical mineral recycling facility. These are some of the key factors driving revenue growth of the market.

Closed-loop cathode active material recovered through hydrometallurgical processing, recycled anode copper foil, and recycled precursor salts feeding new cathode production are the commercial categories that constitute the recycled battery material market, with producers increasingly integrating recycling, refining and remanufacturing into a single facility rather than selling recovered metals as an intermediate commodity to third-party processors. For instance, Redwood Materials disclosed that most of its 2024 revenue came from selling recovered minerals into existing end markets rather than returning them directly to new electric vehicle batteries, reflecting how early the domestic closed-loop battery supply chain remains even for the sector's most advanced participant.

However, two of the sector's most prominent venture-backed recyclers have entered bankruptcy proceedings within the past year, with Li-Cycle entering creditor protection in Canada and the United States in May 2025 after cost overruns and operational failures despite securing a USD 475 million U.S. Department of Energy loan commitment it was ultimately unable to draw down, and Ascend Elements filing for Chapter 11 protection on April 9, 2026 in the U.S. Bankruptcy Court for the Southern District of Texas after the Department of Energy cancelled a combined USD 480 million in grants tied to cathode active material production at its Hopkinsville, Kentucky facility. A 2025 Nature Communications analysis described lithium-ion battery recycling as constrained by technical, economic and regulatory challenges, with global recycling rates still well below those of more established systems such as lead-acid battery recycling. Recovered material revenue also depends on lithium, nickel and cobalt prices that move with global commodity markets independent of any individual recycler's operational performance, adding a further layer of financial volatility on top of execution risk. These factors substantially limit recycled battery material market growth over the forecast period.

Based on material type, the global recycled battery material market is segmented into closed-loop cathode active material, recycled anode copper foil, recycled precursor salts, and other recovered materials. The closed-loop cathode active material segment commands the largest revenue share because cathode material carries the highest value per tonne of any recovered battery component, with Redwood Materials' hydrometallurgical process reclaiming 95 percent of lithium from scrap battery materials and purifying recovered nickel, lithium and other metals into intermediates that feed directly into cathode active material production rather than being sold as a lower-value intermediate commodity.

The recycled anode copper foil segment is expected to register a rapid revenue growth rate in the global recycled battery material market over the forecast period. Redwood Materials' plan to ramp copper foil production to 100 gigawatt-hours of annual capacity, enough to build more than one million electric vehicles a year, addresses a segment where the United States has historically exported hundreds of thousands of tonnes of copper annually while importing nearly all of its anode copper foil from Asian producers, and the segment's growth reflects the scale of import substitution opportunity a domestic closed-loop copper foil supply chain represents relative to the more incremental gains available in an already-established cathode recycling process.
