Cobalt
Cobalt secures high-energy Li-ion cathodes and reinforces nickel super-alloys. Although low-cobalt chemistries are spreading, energy-dense NCM 811 and NCMA batteries plus an aerospace rebound keep absolute demand rising. Roughly three-quarters of ore comes from the DRC and >50 % of refining from China, but Indonesian HPAL projects and battery-metal recycling are redrawing the cost curve and diversifying supply.
Supply Dynamics
-
DRC Cu–Co by-product output dominates; governance & export-ban risks create price spikes.
-
Indonesian HPAL ramps rapidly, challenging Chinese sulfate producers.
-
China controls most conversion capacity; Western cathode plants seek local feed.
-
Recycling lowers carbon footprint and cushions deficits.
-
ESG audits (IRMA/RMI) are now prerequisite for many long-term contracts.
Demand Dynamics
-
EV/ESS battery growth offsets lower cathode intensity.
-
Jet-engine super-alloys recover with record aircraft build-rates.
-
Portable-electronics demand plateaus but remains cobalt-intensive.
-
Secondary supply from spent packs could cover ≈25 % of demand by 2030.
-
OEM sustainability standards favour certified, traceable cobalt, tightening the spot market.
