A wave of strategic partnerships between automakers, battery manufacturers, mining companies, and recyclers is accelerating the development of closed-loop lithium battery ecosystems—vertically integrated supply chains in which materials recovered from spent batteries feed directly back into new cell production. In the past 12 months alone, more than 25 major closed-loop partnership agreements have been announced globally, collectively representing commitments to process hundreds of thousands of tonnes of battery materials annually by 2030.
The shift toward closed-loop arrangements reflects a convergence of pressures. Automakers face regulatory mandates requiring recycled content in new batteries. Cell manufacturers seek stable, low-cost sources of cathode precursors amid volatile commodity markets. And recyclers need guaranteed feedstock volumes to justify the capital expenditure of building commercial-scale facilities. The result is a web of long-term contracts and joint ventures that is reshaping the structure of the battery supply chain.
Landmark Partnerships Driving the Trend
Several recent deals illustrate the scale and scope of closed-loop partnerships now taking shape:
Mercedes-Benz and CATL-Brunp signed a multi-year agreement under which end-of-life battery packs from Mercedes EQ models sold in Europe and China will be collected and processed at Brunp Recycling facilities. The recovered cathode precursor materials will be supplied back to CATL for use in next-generation battery cells destined for Mercedes vehicles. The arrangement covers 50,000 tonnes of battery material per year by 2030.
BMW and Redwood Materials expanded their partnership in mid-2025 to include battery scrap from BMW’s Spartanburg, South Carolina plant and end-of-life packs from BMW’s North American dealer network. Redwood processes the materials at its Nevada campus and supplies recycled nickel, cobalt, lithium, and copper back to BMW’s battery cell suppliers. BMW has stated that at least 20% of the critical raw materials in its Neue Klasse battery cells will come from recycled sources by 2030.
Stellantis and Orano launched a joint venture in France dedicated to recycling end-of-life EV batteries from Stellantis brands (Peugeot, Citroën, Fiat, Opel) and manufacturing scrap from the ACC (Automotive Cells Company) gigafactory in Billy-Berclau. The joint venture’s first facility will have initial capacity of 15,000 tonnes per year, with plans to triple capacity by 2032.
“Closed-loop partnerships are no longer experimental—they are becoming standard operating procedure for any automaker serious about meeting recycled content regulations and managing supply chain risk. The question is not whether to do it, but how fast you can build the infrastructure.” — Dr. Tim Johnston, Executive Chairman, Li-Cycle Holdings
The Economics of Integration
Closed-loop systems offer economic advantages that arm’s-length transactions do not. By securing offtake agreements in advance, recyclers reduce the commercial risk of building expensive processing facilities. Automakers, in turn, gain cost visibility: recycled cathode materials produced under long-term contracts can be priced below spot market rates for virgin equivalents, particularly during periods of commodity price spikes.
According to analysis by Benchmark Mineral Intelligence, recycled nickel sulfate can be produced at 25–35% lower cost than conventional Class 1 nickel refining, depending on the source material and processing route. Recycled lithium carbonate from hydrometallurgical processes has achieved production costs of $6,000–$8,000 per tonne, compared to $10,000–$14,000 per tonne for brine-extracted lithium carbonate at current yield rates.
These cost advantages become more pronounced as recycling technology matures and facilities achieve higher utilization rates. The critical threshold, according to industry analysts, is sustained operation at or above 80% of nameplate capacity—a milestone that only a handful of recyclers have reached to date.
- Redwood Materials: Operating its Nevada facility at 75% utilization; targeting 100 GWh annual capacity by 2030
- Li-Cycle: Rochester Hub facility commissioning delayed but now operational; processing NMC and LFP chemistries
- Ascend Elements: Apex 1 facility in Hopkinsville, Kentucky ramping production of engineered cathode active materials from recycled feedstock
- Northvolt Revolt: Integrated recycling into cell production at its Skellefteå facility; has produced cells with 50% recycled nickel content
Challenges and Outlook
Despite the momentum, closed-loop ecosystems face persistent challenges. Cross-border logistics add complexity when batteries retired in one country must be transported to recycling facilities in another—a scenario complicated by hazardous materials shipping regulations. Standardization of battery design for recyclability remains limited, with significant variation in pack architecture, cell formats, and adhesive systems across manufacturers.
There is also the chemistry transition to contend with. As the industry shifts from NMC toward LFP and emerging chemistries like sodium-ion, closed-loop partnerships designed around one cathode chemistry may need to be restructured. Recyclers with flexible processing capabilities—able to handle multiple chemistries without major retooling—will have a structural advantage.
Still, the trajectory is clear. The battery supply chain is moving from a linear model of mine-manufacture-dispose toward an integrated circular system in which recycling is not an afterthought but a core link in the value chain. The partnerships being forged today are laying the groundwork for what will become a $24 billion industry by 2035—one in which the concept of battery waste becomes, in practical terms, obsolete.
