1. Precious Metal Composition Analysis
Key Metal Content (based on European black mass samples and Chinese recycling process data):
Cobalt (Co): ~ 15.79% in ternary lithium batteries (e.g., NCM811), <0.5% in LFP (lithium iron phosphate) black mass.
Nickel (Ni): 6.94%–20% in ternary black mass (up to 60%+ in high-nickel systems like NCM811).
Lithium (Li): ~3. 19% in LFP black mass, ~2.5%–4% in ternary black mass.
Copper (Cu)/Aluminum (Al): Cu: 1.97%–5%, Al: 5. 13% (from current collectors and structural components).
Others: Manganese (Mn) ~4.82%, fluorine (F), and impurities requiring wet-process purification.
