Atomic #28
battery
The backbone of stainless steel and the key to long-range EV batteries, dominated by Indonesian expansion.
Nickel is a hard, silvery-white transition metal valued for its strength, corrosion resistance, and high-temperature performance. While roughly 65% is used for stainless steel, battery-grade nickel is the fastest-growing demand segment, essential for high-energy-density cathodes (NMC/NCA). The supply chain is being reshaped by Indonesia, which now controls ~50% of global mine production through a carbon-intensive laterite processing boom.

| Grade | Specification | Form | Applications | Impurity Limits |
|---|---|---|---|---|
| Class I Nickel | ≥99.8% Ni | Refined metal, briquettes, powders | Superalloys, precursor to battery-grade sulfate | Extremely low iron, cobalt, and copper |
| Battery-Grade Nickel Sulfate | NiSO₄·6H₂O | Crystalline salt | NMC and NCA battery cathodes | Strict limits to prevent battery degradation |
| Class II: Nickel Pig Iron (NPI) | 4-15% Ni | Pig iron ingots | Direct feed for stainless steel manufacturing | — |

From Source to Industry
Structural Bottlenecks
Mining HHI
Indonesia ≈50%, Top 3 >70%. High concentration.
Refining HHI
Indonesia & China dominate Class II and MHP processing.
Chokepoints
Indonesia's ore export bans forced massive domestic smelter and HPAL build-outs, capturing almost all recent global supply growth.
Impact
Extreme geographic concentration and reliance on Indonesian policy and ESG practices.
Mitigation
Development of sulfide and laterite projects in North America, Australia, and Africa.
Indonesian processing (especially NPI-to-matte and HPAL) relies heavily on captive coal power. Laterite mining also drives deforestation.
Impact
Western OEMs face challenges reconciling the need for nickel with Scope 3 emissions and ESG commitments.
Mitigation
Transitioning to renewable power for processing, stricter tailings management (avoiding deep-sea disposal).
There is a massive surplus of Class II nickel (NPI) used in steel, depressing global prices, while Class I (battery-grade sulfate) remains strategically tighter.
Impact
Low benchmark prices stall investment in higher-quality, lower-emission sulfide projects outside Indonesia.
Mitigation
Potential bifurcation of pricing: a 'green premium' for low-carbon Class I nickel.
What Could Replace Nickel?
LFP (Lithium Iron Phosphate)
Replacing in: EV Batteries
Zero nickel. Lower energy density but cheaper and safer. Dominating standard-range EVs.
Trend: Massive market share capture, particularly in China.
Other Stainless Grades
Replacing in: Stainless Steel
Ferritic or duplex stainless steels use less or no nickel, but lack the extreme corrosion resistance of austenitic grades.
Key Events
2014 & 2020
Indonesian Government
Banned export of raw laterite ore, forcing tens of billions in foreign direct investment into domestic smelters.
Jul 2023
European Union
Mandates supply chain due diligence from Aug 2027. Recyclers must recover 95% of nickel by 2031.
Aug 2031
European Union
New EV/industrial batteries must contain ≥6% recycled nickel, rising to 15% by 2036.
Leading Indicators
Indonesian ESG Legislation
Western OEMs require cleaner supply chains; Indonesia must green its grid and ban deep-sea tailings to maintain Western market access.

Frequently Asked Questions
Class I nickel is high purity (≥99.8% Ni) and is required to make nickel sulfate for EV batteries. Class II nickel (like Nickel Pig Iron or Ferronickel) has lower purity (4-40% Ni) and is used directly in stainless steel production.
While Indonesia has successfully scaled production to meet EV demand, its processing methods (HPAL and NPI-to-matte) are highly energy-intensive and largely powered by coal. Additionally, mining laterite ores in tropical regions poses severe risks of deforestation and tailings management issues.
LFP (Lithium Iron Phosphate) contains zero nickel and is gaining massive market share for standard-range EVs and grid storage. However, premium and long-range EVs still require high-nickel NMC/NCA cathodes. Nickel demand for batteries is still projected to grow significantly in absolute terms, even if its market share drops.
