Recycling — the Highest-Grade Deposit Is in the Vehicle Park
A copper mine at 0.6 per cent is economic. A cathode is 20 per cent nickel and 12 per cent cobalt. Spent batteries are, by grade, the richest ore body on the planet.

Part 5 — The Second Chain
Ore grades that would be a world-class mine
A copper mine at 0.6 per cent is economic. A cathode is 20 per cent nickel and 12 per cent cobalt.
Spent batteries are, by grade, the richest ore body on the planet — and the obstacles are collection and logistics, not metallurgy.

14.1 — The richest ore body on the planet
Black mass is one to two orders of magnitude richer than the ore these metals originally came from. Manganese is the exception, and it is the one nobody bothers recovering. Recycling was never a chemistry problem.
14.2 — Three routes, and what each loses
- •1 · Deactivation and disassembly. Discharge fully, or freeze and inert; remove casing, wiring, BMS and cooling. This is the step that resists automation, because every pack is designed differently.
- •2 · Shredding to black mass. Shred under inert atmosphere or brine, separate Cu and Al foil, steel and plastics by density and eddy current. What remains is a powder of Li, Ni, Co, Mn and graphite — the traded intermediate, which now moves internationally like a concentrate.
- •3a · Pyrometallurgy. Smelt it, recovering Ni, Co and Cu as an alloy. Lithium, graphite, manganese and aluminium are lost to slag. Simple, tolerant of mixed feed, and wasteful.
- •3b · Hydrometallurgy — the dominant route. LiNiMnCoO₂ + H₂SO₄ + H₂O₂ → Li₂SO₄ + NiSO₄ + CoSO₄ + MnSO₄, then solvent extraction exactly as in the primary chain, back to battery-grade sulfates. Recovers 90 %+ of Ni, Co, Cu and increasingly Li.
- •3c · Direct recycling. Recover the cathode powder intact, relithiate it, reuse it without breaking it down to elements. Highest theoretical value and lowest energy; needs clean, sorted, single-chemistry feed — which is why it works on production scrap and struggles with end-of-life mixtures.
14.3 — LFP’s structural economics problem
Important
The business case for recycling was built on nickel and cobalt. An LFP cell contains iron and phosphate — cheap, abundant, and not worth much recovered. The lithium alone often does not pay for collection and processing.
As LFP takes share, recycling economics get worse exactly as volumes get larger, which is the opposite of what everyone planned for. This is a real argument for regulation-driven collection like India’s EPR framework rather than market-driven recovery.
14.4 — Where the feedstock actually comes from
Technical framing
Today it is manufacturing scrap, not end-of-life vehicles. A new cell plant scraps 5 to 15 per cent of output during ramp, and those cells are clean, single-chemistry and already at the recycler’s gate.
End-of-life EV batteries arrive in volume only when today’s vehicles retire, which is a decade or more out. That timing is why direct recycling looks so much better in pilot data than it will in a mature market.

Chapter summary
- ✓Black mass is one to two orders of magnitude richer than the primary ore these metals came from, so recycling has never been a chemistry problem.
- ✓Pyrometallurgy is simple and loses lithium, graphite, manganese and aluminium to slag; hydrometallurgy dominates and recovers over 90 per cent of Ni, Co and Cu.
- ✓Direct recycling has the highest theoretical value but needs clean single-chemistry feed, which is why it suits production scrap.
- ✓LFP breaks the economics: iron and phosphate are not worth recovering, so the case worsens exactly as volumes grow.
- ✓Today’s feedstock is manufacturing scrap; end-of-life vehicles are a decade or more away from arriving in volume.
Frequently asked questions
Why is recycling not a chemistry problem?+
Because the grades are extraordinary. A cathode is around 20 per cent nickel and 12 per cent cobalt against primary ores at 1.3 and 0.3 per cent respectively — black mass is one to two orders of magnitude richer than the ore these metals originally came from, in a known location and a known chemistry. The obstacles are collection, disassembly and logistics, and disassembly resists automation because every pack is designed differently.
What is the difference between the three recycling routes?+
Pyrometallurgy smelts the black mass and recovers nickel, cobalt and copper as an alloy, but lithium, graphite, manganese and aluminium are lost to slag — simple, tolerant of mixed feed, and wasteful. Hydrometallurgy leaches with sulfuric acid and peroxide then uses solvent extraction, exactly as in the primary chain, recovering over 90 per cent of Ni, Co and Cu and increasingly Li; it dominates. Direct recycling recovers the cathode powder intact and relithiates it — highest theoretical value and lowest energy, but it needs clean, sorted, single-chemistry feed.
Why does LFP make recycling harder?+
Because the business case was built on nickel and cobalt. An LFP cell contains iron and phosphate — cheap, abundant, and not worth much recovered — so the lithium alone often does not pay for collection and processing. As LFP takes share, recycling economics get worse exactly as volumes get larger, which is the opposite of what everyone planned for. It is a real argument for regulation-driven collection such as India’s EPR framework rather than market-driven recovery.
Where does recycling feedstock actually come from today?+
Manufacturing scrap, not end-of-life vehicles. A new cell plant scraps 5 to 15 per cent of output during ramp, and those cells are clean, single-chemistry and already at the recycler’s gate. End-of-life EV batteries arrive in volume only when today’s vehicles retire, which is a decade or more out.
