Cobalt — The Battery Metal

What Is Cobalt and Why Does It Matter?

Cobalt is a hard, lustrous, silver-grey metal essential to modern technology. Its primary importance lies in lithium-ion batteries, where cobalt-containing cathode chemistries — particularly nickel-cobalt-manganese (NCM) and nickel-cobalt-aluminium (NCA) — deliver the energy density required for high-performance electric vehicles and consumer electronics. Approximately 57% of global cobalt demand comes from the battery sector, with superalloys for jet engines and industrial catalysts accounting for most of the remainder.

The DRC's dominance is unparalleled among critical minerals. No other country controls such a large share of any single mineral essential to the energy transition. This concentration creates both extraordinary leverage for the DRC and significant supply chain vulnerability for consuming nations — a dynamic that shaped the dramatic events of 2025.

The 2025 Export Ban and Quota System

In February 2025, with cobalt prices at a nine-year low of approximately $21,500 per tonne, the DRC imposed a complete suspension of cobalt exports. The ban was a direct assertion of mineral sovereignty, aiming to address chronic oversupply driven largely by expanded production at Chinese-operated mines. The suspension was initially set for four months, then extended in June to September, and ultimately resolved in October with the introduction of a structured quota system.

The impact was dramatic. Cobalt prices surged from $21,500 to approximately $48,570 per tonne by October 2025, demonstrating the DRC's unparalleled market leverage. The quota system, administered by the DRC's ARECOMS regulatory authority, permits a maximum of approximately 96,600 tonnes annually for 2026-2027 — roughly half of pre-ban export volumes. ARECOMS reserves the right to adjust volumes quarterly based on market conditions.

The DRC's cobalt export controls represent the most ambitious assertion of mineral sovereignty in Africa in decades, comparable in ambition (if not yet in execution) to OPEC's management of oil markets. The quota system aims to balance several objectives: stabilising prices, incentivising domestic processing, and increasing state revenue capture from strategic mineral resources.

Global Supply Chain

The cobalt supply chain is extraordinarily concentrated. The DRC accounts for 72-78% of mine production, with Indonesia a distant second at approximately 15% and growing rapidly through high-pressure acid leach (HPAL) processing of nickel laterites. Russia produces approximately 2%, with Australia, Canada, and other minor producers comprising the remainder.

Critically, cobalt is overwhelmingly produced as a by-product of copper and nickel mining. In the DRC, cobalt is co-produced with copper; in Indonesia, with nickel. This structural dependency means cobalt supply responds to copper and nickel market dynamics rather than cobalt-specific fundamentals, reducing supply flexibility and amplifying volatility.

China controls nearly 80% of global cobalt refining, processing DRC-mined cobalt hydroxide into battery-grade materials. This processing bottleneck gives China disproportionate influence over the cobalt supply chain even beyond its investment ownership of DRC mines, where Chinese firms control approximately 70-80% of industrial production.

Corridor Mines Producing Cobalt

Artisanal and Small-Scale Mining

Artisanal and small-scale mining (ASM) remains a critical dimension of the DRC's cobalt sector, employing an estimated 2 million people directly and supporting over 10 million indirectly. ASM accounts for a declining but still significant share of DRC cobalt output, with production concentrated around Kolwezi in Lualaba Province.

The Entreprise Générale du Cobalt (EGC), a state-owned subsidiary of Gecamines, holds exclusive purchasing rights for artisanal cobalt. In November 2025, EGC announced its first 1,000 tonnes of fully traceable artisanal cobalt, a milestone in formalisation efforts. In February 2026, EGC made its first shipment via the Lobito Corridor through Trafigura, marking a symbolic convergence of artisanal formalisation and corridor logistics.

Child labour in artisanal cobalt mining has drawn extensive international scrutiny, driving some battery manufacturers toward cobalt-free chemistries. Lithium iron phosphate (LFP) batteries, which contain no cobalt, now represent over 60% of global battery cell capacity, though NCM chemistries continue to dominate premium vehicle segments where energy density is critical.

Battery Chemistry and Substitution Risk

The shift toward lower-cobalt and cobalt-free battery chemistries represents the most significant long-term demand risk. LFP batteries have rapidly gained market share, driven by cost advantages, growing Chinese adoption, and entry-level EV demand. However, NCM and NCA chemistries retain critical advantages in energy density, making them essential for high-performance vehicles and long-range applications particularly valued in North American and European markets.

Battery recycling represents both a supply supplement and a demand modifier. Black mass recycling can recover cobalt from end-of-life batteries, potentially reducing primary mining demand over the long term. However, recycled cobalt volumes remain small relative to primary production and will not meaningfully impact supply dynamics before the 2030s.

The DRC Monopoly Problem

No other critical mineral presents the concentration risk that cobalt does. The DRC's 76% share of global cobalt production creates a single point of failure for the entire global battery supply chain. A major disruption to DRC cobalt output — whether from political instability, regulatory action, conflict, or infrastructure failure — would cascade through battery manufacturing, electric vehicle production, consumer electronics, and aerospace industries worldwide.

This concentration risk is compounded by Chinese dominance of cobalt processing. Chinese companies, led by CMOC and CNMC, control the majority of DRC cobalt mining and nearly all cobalt refining globally. The supply chain from DRC mine to Chinese refinery to battery cathode to EV represents a critical vulnerability that Western governments are actively seeking to address — and the Lobito Corridor is central to their strategy.

The US-DRC Strategic Partnership of December 2025, which targets routing 50% of DRC copper through the corridor, implicitly targets cobalt supply chain diversification. If DRC cobalt can reach Western markets through Lobito rather than through Chinese-controlled east African routes, it reduces Beijing's chokehold on battery materials.

Artisanal Cobalt: The Human Rights Dimension

Approximately 15-30% of DRC cobalt comes from artisanal and small-scale mining (ASM), which employs an estimated 200,000-300,000 miners in the Copperbelt. Artisanal cobalt mining has been the subject of intense international scrutiny due to hazardous working conditions, child labour, and the absence of basic safety equipment. Amnesty International, Global Witness, and academic researchers have documented deaths, injuries, and exploitation in artisanal cobalt mining.

The Entreprise Générale du Cobalt (EGC), established by the DRC government in 2019 with a monopoly on artisanal cobalt purchasing, aims to formalise the sector and improve traceability. The first EGC shipment through the Lobito Corridor in February 2026 represents a critical test of whether formalisation can deliver fair prices to artisanal miners while meeting international due diligence standards. Our artisanal mining analysis and child labour investigation examine these challenges in depth.

The corridor's role in artisanal cobalt is significant: if the Lobito route can offer traceable, certified-clean artisanal cobalt to Western manufacturers, it creates a premium market channel that incentivises responsible mining practices. If the corridor merely provides cheaper transport for un-traced cobalt, it fails the communities it should serve.

Battery Chemistry Evolution and Demand Outlook

Cobalt demand is shaped by competing forces: growing battery production drives demand upward, while battery chemistry innovation drives cobalt intensity downward. The shift from NMC 111 (equal parts nickel, manganese, cobalt) to NMC 811 (80% nickel, 10% each manganese and cobalt) has reduced cobalt per battery by approximately 60%. Lithium iron phosphate (LFP) batteries, which contain zero cobalt, now represent over 40% of the global EV battery market.

Despite these trends, absolute cobalt demand continues to grow because total battery production is expanding faster than cobalt intensity is declining. The Cobalt Institute projects global cobalt demand reaching 250,000+ tonnes by 2030, up from approximately 200,000 tonnes in 2024. The DRC will remain the dominant source regardless of chemistry shifts.

The cobalt price collapse of 2023-2024 — driven by DRC oversupply and the LFP shift — devastated artisanal mining communities but did not fundamentally alter the DRC's strategic importance. Prices have partially recovered in early 2026, and the structural deficit projected for the late 2020s suggests sustained price recovery as battery production scales.

Cobalt Regulatory Framework

Cobalt is subject to increasing responsible-sourcing scrutiny, but it should not be treated as a 3TG mineral. The US Dodd-Frank Act Section 1502 covers tin, tantalum, tungsten, and gold, not cobalt. The EU Conflict Minerals Regulation likewise focuses on 3TG. Cobalt due diligence is more commonly driven by the OECD Due Diligence Guidance, battery supply-chain expectations, customer policies, lender safeguards, and broader human-rights due-diligence frameworks.

For institutional buyers, the distinction matters. Calling cobalt a legal conflict mineral can overstate the rule. Treating cobalt as low-risk because it is not 3TG understates the market reality. The credible position is that DRC cobalt is a high-scrutiny responsible-sourcing category that requires traceability, risk assessment, mitigation, and careful disclosure.

Buyer Due Diligence

A cobalt diligence file should connect mine or production area, processor, trader, export route, custody evidence, ASM exposure, child-labour controls, safety practices, and grievance mechanisms. Where cobalt is routed through Lobito, buyers should also test whether the logistics claim improves traceability or merely changes the export route for material whose origin and custody remain unclear.

What to Monitor

Monitor ARECOMS quota administration, EGC purchasing and shipment evidence, ASM formalisation claims, buyer audit results, processor mixing practices, and whether downstream manufacturers distinguish between legal 3TG compliance and broader cobalt responsible-sourcing risk. The best corridor signal is traceable volume growth with specific mine, processor, and export documentation.
