Nickel-rich lithium-ion batteries: What to track
Cobalt politics, the LFP price gap and safer high-nickel cells
What this tab covers The attributes worth tracking regularly, with the latest value, the direction of travel and why each matters.Track cobalt and nickel prices and policy, the NMC to LFP price gap, and whether high-nickel cells close the safety and life gap.
| Category | Attribute | Latest | Trend | Why it matters |
|---|---|---|---|---|
| Techno-economic | LCOS trajectory | No NMC-specific benchmark; lithium-ion 100 MW, 4 h US LCOS USD 210-292/MWh (2026)12 | ↘ worsening | Benchmarks have moved to LFP, a sign NMC is leaving grid storage. |
| Techno-economic | Capacity fade and state of health | NMC about 1,200 cycles at 80% depth of discharge (2020 US grid basis); LTO 20,000 cycles to 70% capacity (Toshiba claim)615 | ↗ improving | Coatings and single-crystal cathodes aim to extend life; field data will show if it works. |
| Supply chain | Critical mineral cost and geopolitical concentration | Cobalt prices doubled over the year after the DRC export ban (February 2025) and quotas (from 16 Oct 2025); DRC supplies almost two-thirds of cobalt2 | ↕ volatile | A single-country policy can move cathode costs sharply. |
| Market | Ancillary service market saturation | LFP takes over 90% of new storage, crowding the fast-response markets where LTO competes2 | ↘ worsening | Cheaper LFP fleets push down frequency service prices. |
| Compliance | Safety and environmental compliance | NFPA 855 (2026) large-scale fire testing; EU battery passport from 18 Feb 2027; EU due diligence (cobalt, nickel, lithium, natural graphite) postponed from 18 Aug 2025 to 18 Aug 2027101718 | ↗ improving | Due diligence rules make cobalt sourcing a direct compliance risk. |
| Impact | Lifecycle carbon payback period | No sourced figure; the EU carbon footprint declaration for EV batteries applies only 12 months after the Commission adopts its calculation rules17 | → stable | Nickel from coal-powered Indonesian smelters raises embodied emissions. |
| Technology-specific | NMC price premium over LFP | USD 128/kWh versus USD 81/kWh (2025)1 | ↘ worsening | A widening gap pushes NMC out of storage and mid-range cars. |
| Technology-specific | Cobalt content per cell | About 10% of metal content in NMC811 and NMC721; about 15% in NCA2 | ↗ improving | Lower cobalt reduces cost and ethical exposure. |
