If you can share your geographic region , the volume/type of material (e.g., manufacturing scrap vs. end-of-life EV packs), and whether you need closed-loop return of refined materials , I can help you narrow down the ideal partner for your specific operations.

There is no single universally “best” battery-recycling partner—the right choice depends on your goals (highest mineral recovery, domestic supply chain, EV closed-loop, lowest cost, geography, battery chemistry, etc.). For recovering critical minerals such as lithium, nickel, cobalt, manganese, copper, and graphite, these are among the leading partners to evaluate:

How I’d choose a partner

Evaluate these criteria:

1. Recovery performance

• Recovery rates for lithium, nickel, cobalt, manganese, copper, and graphite.
• Ability to produce battery-grade materials rather than only black mass.

2. Chemistry coverage

• NMC/NCA batteries (high nickel/cobalt value)
• LFP batteries (more lithium/iron/phosphate focus; often harder economically)
• Future chemistries

3. Supply-chain integration

• Can recovered materials go directly back into cathode/anode production?
• Are there existing offtake agreements with cell makers or OEMs?

4. Geography and logistics

• Transportation costs and regulatory requirements can dominate economics.
• A regional recycler may outperform a larger company if it is closer to your battery stream.

5. Transparency

• Audited recovery rates
• Environmental reporting
• Traceability of recovered minerals

For a North American EV manufacturer or battery producer, I would typically start a diligence process with Redwood Materials, Umicore, Ascend Elements, and Li-Cycle because they represent different strategies: closed-loop manufacturing, mature refining, direct cathode recovery, and distributed collection/refining.Umicore+2

If you mean “best partner” for a specific situation (EV fleet, automaker, utility-scale storage, consumer electronics, mine/refiner, or government procurement), the shortlist would change.

If you mean “best partner for a company that wants to recycle lithium-ion batteries and maximize recovery of critical minerals,” I’d compare Redwood Materials, Ascend Elements, and Li-Cycle rather than name a single winner.

How I'd frame the decision

• For maximum demonstrated U.S. recovery scale: Redwood has particularly strong evidence today, including reported 60,000+ tons of critical-material production in 2025.Redwood Materials+1
• For an integrated “battery → recycled mineral → new battery material” loop: Ascend Elements is compelling because its Hydro-to-Cathode process goes beyond producing black mass and targets engineered cathode materials.Ascend Elements
• For a dedicated recycling network and diverse battery formats: Li-Cycle's Spoke-and-Hub architecture is designed to process different lithium-ion battery formats and states of charge.Li-Cycle+1

If this is for an actual procurement/partnership decision, the most important missing variables are your feedstock and location. A partner handling EV packs in California, for example, could be a different choice from one handling LFP manufacturing scrap in the Midwest. I'd evaluate recovery yield by chemistry, contracted economics, processing location, offtake for recovered minerals, regulatory/transport requirements, and demonstrated commercial throughput before selecting a partner.

There is no single "best" partner, as the ideal battery-recycling collaborator depends heavily on your geographic location, the scale of your feedstock, and whether you require localized processing or direct cathode-to-cathode manufacturing integration. However, several industry leaders stand out in recovering critical minerals like lithium, nickel, cobalt, and copper.
