Myth-busting Critical minerals supply chains (lithium, cobalt, rare earths): separating hype from reality

The International Energy Agency's 2025 Critical Minerals Market Review found that global demand for lithium grew 30% year-over-year while cobalt demand rose 15%, yet public discourse about these supply chains remains dominated by myths that distort investment decisions, policy design, and procurement strategy. With the energy transition projected to require a sixfold increase in critical mineral inputs by 2040 compared to 2020 levels (IEA, 2025), decision-makers who base strategy on misconceptions rather than evidence risk misallocating billions. This article dissects the five most persistent myths about critical minerals supply chains, presents the data behind each, and offers practical corrections for founders, investors, and procurement leaders.

Why It Matters

Critical minerals underpin nearly every pillar of the energy transition. Lithium-ion batteries power electric vehicles and grid storage systems. Rare earth elements are essential for permanent magnets in wind turbines and EV motors. Cobalt stabilizes cathode chemistry in high-energy-density batteries. Nickel, manganese, graphite, and copper play indispensable roles across solar panels, power electronics, and transmission infrastructure.

The concentration of processing capacity creates genuine strategic vulnerability. China refined 73% of global lithium, 68% of cobalt, and 90% of rare earth elements in 2024 (US Geological Survey, 2025). The EU Critical Raw Materials Act, the US Inflation Reduction Act's sourcing requirements, and Australia's Critical Minerals Strategy all respond to this concentration, but the policies they produce are only as effective as the assumptions behind them.

For founders building in battery technology, EV infrastructure, renewable energy, or circular economy solutions, understanding the actual dynamics of critical mineral supply chains determines whether business models are resilient or fragile. For investors, accurate risk assessment of mineral supply exposure separates winners from stranded assets.

Key Concepts

Critical minerals are typically defined as minerals essential to economic or national security with supply chains vulnerable to disruption. The EU lists 34 critical raw materials; the US Department of Energy identifies 17 minerals as critical to clean energy. The overlap is substantial but not identical, reflecting different economic exposures.

Supply chain stages span extraction (mining), processing (refining and chemical conversion), manufacturing (component fabrication), and end-of-life management (recycling and recovery). Bottlenecks exist at each stage but are most acute at the processing stage, where geographic concentration far exceeds that of raw ore extraction.

Reserves refer to economically extractable quantities at current prices and technology. Resources represent total identified geological deposits regardless of current economic viability. Conflating the two is a frequent source of confusion in public debate about "running out" of specific minerals.

Myth 1: We Are Running Out of Lithium

This narrative resurfaces every time lithium prices spike, as they did in late 2022 when lithium carbonate spot prices exceeded $80,000 per metric ton. The data tells a different story. The US Geological Survey estimated identified global lithium resources at 105 million metric tons in 2025, up from 98 million in 2024, as new deposits were identified in Serbia, Canada, and Argentina (USGS, 2025). At current consumption rates of approximately 180,000 metric tons of lithium carbonate equivalent per year, identified resources represent over 500 years of supply.

The real constraint is not geological scarcity but development timelines. Bringing a new lithium mine from discovery to production takes 7 to 15 years due to permitting, environmental impact assessments, community engagement, and construction. The bottleneck is throughput, not total availability. Rio Tinto's Jadar project in Serbia illustrates this: the deposit contains approximately 58 million metric tons of lithium-boron ore, enough to supply 17% of European EV battery demand, yet permitting delays pushed first production from 2027 to at least 2029.

The practical correction: scarcity risk in lithium is a flow problem, not a stock problem. Founders and investors should evaluate mine development pipelines and permitting timelines rather than absolute reserve figures. Companies dependent on lithium supply should secure offtake agreements three to five years ahead and diversify across brine, hard rock, and direct lithium extraction (DLE) sources.

Myth 2: Cobalt Cannot Be Eliminated from Battery Chemistry

The narrative that cobalt is an irreplaceable component of lithium-ion batteries persists despite clear market evidence to the contrary. In 2024, lithium iron phosphate (LFP) batteries, which contain zero cobalt, accounted for 41% of global EV battery installations, up from 32% in 2023 (BloombergNEF, 2025). CATL's Shenxing LFP battery demonstrated 400 kilometers of range from a 10-minute charge, directly challenging the performance argument for cobalt-containing chemistries.

Tesla's standard-range Model 3 and Model Y vehicles have used cobalt-free LFP cells since 2021. BYD's entire Blade Battery lineup is LFP-based. For energy storage systems, where weight is less critical than for vehicles, LFP dominance is even more pronounced at 78% market share for new installations in 2024 (Wood Mackenzie, 2025).

That said, cobalt-containing chemistries (NMC and NCA) still offer higher energy density per kilogram, making them the preferred choice for premium EVs and aviation applications where range-to-weight ratio is paramount. The trajectory is clear: cobalt demand growth is decoupling from overall battery market growth. Benchmark Mineral Intelligence projects cobalt demand growth of 3 to 5% annually through 2030, compared to 25% annual growth in total battery capacity.

The practical correction: for most battery applications, cobalt dependency is a choice, not a constraint. Founders building battery-dependent products should evaluate LFP and sodium-ion alternatives before defaulting to cobalt-containing chemistries. Investors should apply a cobalt risk discount to companies locked into NMC-only supply chains without diversification roadmaps.

Myth 3: Recycling Will Solve Critical Mineral Supply Gaps Within This Decade

The circular economy narrative around battery recycling is compelling but the timeline expectations are unrerealistic. The average EV battery has a service life of 10 to 15 years in a vehicle, followed by a potential second life of 5 to 10 years in stationary storage. Since mass EV adoption began around 2018 to 2020, the first significant wave of end-of-life batteries will not arrive until 2028 to 2035.

In 2024, recycled materials contributed approximately 5% of lithium supply, 15% of cobalt supply, and less than 1% of rare earth supply globally (Circular Energy Storage, 2025). Even under optimistic projections, the IEA estimates that recycling will meet no more than 12% of lithium demand and 20% of cobalt demand by 2030.

Li-Cycle, once valued at $2.8 billion, paused construction of its Rochester, New York hub in 2023 after costs ballooned from $485 million to $960 million. Redwood Materials, backed by $1 billion in funding, is progressing but processes only 50,000 metric tons of battery materials annually, a fraction of the millions of metric tons that will eventually be needed. These companies are building essential infrastructure, but the economics and scale remain challenging.

The practical correction: recycling is a critical long-term complement to mining, not a near-term substitute. Companies should design products for recyclability now to capture future value, but supply strategies for 2025 to 2035 must remain anchored in primary extraction and diversified sourcing.

Myth 4: Rare Earth Elements Are Actually Rare

Despite their name, most rare earth elements are not geologically scarce. Cerium, the most abundant rare earth, is more common in the Earth's crust than copper. The challenge is not abundance but concentration and separation. Rare earth elements rarely occur in concentrated deposits, and separating the 17 chemically similar elements from each other requires complex, energy-intensive, and often environmentally hazardous hydrometallurgical processes.

China's dominance in rare earth processing (90% of global refined output in 2024) reflects decades of industrial policy, process optimization, and tolerance for the environmental costs of separation, not geological monopoly. The Mountain Pass mine in California, operated by MP Materials, produced 43,000 metric tons of rare earth concentrate in 2024 but shipped most of it to China for processing because domestic separation capacity was insufficient (MP Materials, 2025).

Lynas Rare Earths in Australia commissioned its Kalgoorlie processing facility in 2023, representing the only significant non-Chinese rare earth separation capacity outside of limited operations in Estonia and Japan. The EU plans to process 40% of its rare earth needs domestically by 2030 under the Critical Raw Materials Act, but current capacity sits below 3%.

The practical correction: the rare earth supply risk is a processing bottleneck, not a mining shortfall. Founders in wind energy, EV motors, or defense technologies should evaluate supply chain exposure at the processing stage specifically. Diversification strategies must address refining capacity, not just ore sourcing.

Myth 5: Western Countries Can Quickly Replicate China's Critical Minerals Processing Capacity

Political rhetoric around "reshoring" or "friendshoring" critical mineral processing often implies that capacity can be rebuilt within a few years given sufficient investment. The evidence suggests otherwise. China spent approximately 30 years building its current critical minerals processing infrastructure, supported by consistent industrial policy, environmental trade-offs that would be unacceptable under Western regulatory frameworks, and massive workforce development.

The US Department of Energy's Loan Programs Office committed $2.5 billion in 2024 to domestic lithium and battery material processing, yet the Congressional Research Service estimates that reaching 50% self-sufficiency in lithium processing alone would require 8 to 12 years and $15 to $20 billion in cumulative investment (CRS, 2025). Permitting timelines in the US average 7 to 10 years for new chemical processing facilities, compared to 2 to 3 years in China.

Indonesia's nickel processing buildout offers a cautionary parallel. Despite abundant nickel laterite resources and aggressive government mandates banning raw ore exports since 2020, Indonesia achieved competitive processing economics only by accepting environmental standards that drew international criticism for deforestation and water pollution associated with smelter operations.

The practical correction: supply chain diversification away from China is necessary but will take 10 to 15 years under realistic assumptions. Founders and investors should plan for continued Chinese processing dependency through at least 2035 while supporting and investing in alternative processing capacity. Strategies that assume rapid reshoring are building on sand.

What's Working

Direct lithium extraction (DLE) technology is accelerating project timelines and expanding the viable resource base. Lilac Solutions, EnergyX, and SLB (formerly Schlumberger) are deploying DLE pilots that recover lithium from brines at higher rates and with smaller environmental footprints than traditional evaporation ponds. Lilac Solutions' pilot in Argentina achieved 90% lithium recovery rates versus 40 to 50% for conventional evaporation (Lilac Solutions, 2025).

The Inflation Reduction Act's 30D tax credit requirements, which mandate increasing percentages of battery minerals sourced from the US or free-trade partners, are driving real investment. Over $120 billion in battery supply chain investments were announced in the US between 2022 and 2025 (Department of Energy, 2025).

Glencore, Umicore, and BASF have established closed-loop recycling partnerships where battery production scrap is recycled back into precursor materials within the same supply chain, achieving 95% recovery rates for cobalt, nickel, and manganese from manufacturing waste.

What's Not Working

Artisanal and small-scale mining (ASM) in the Democratic Republic of Congo, which produces approximately 15 to 20% of global cobalt, continues to face documented child labor and unsafe working conditions despite industry initiatives. The Responsible Minerals Initiative certifies smelters and refiners, but traceability breaks down between mine site and smelter for ASM-sourced material.

Deep-sea mining proponents argue that polymetallic nodules on the ocean floor could supply decades of nickel, cobalt, and manganese. The International Seabed Authority has yet to finalize mining regulations, and scientific opposition is intensifying. A 2024 petition signed by over 800 marine scientists called for a moratorium, citing irreversible damage to poorly understood deep-ocean ecosystems (Deep Sea Conservation Coalition, 2024).

Sodium-ion batteries, often cited as the solution to lithium dependency, face their own scaling challenges. While CATL and BYD began commercial sodium-ion production in 2024, energy density remains 30 to 40% below LFP and cycle life is still being validated in field conditions. Sodium-ion is viable for stationary storage and two-wheelers but is unlikely to displace lithium in mainstream EVs before 2030.

FAQ

Q: Should we avoid investing in cobalt-dependent battery technologies entirely? A: Not necessarily. Cobalt-containing NMC and NCA chemistries still offer the highest energy density for applications where weight and volume matter, such as long-range premium EVs and urban air mobility. The key is ensuring supply diversification across geographies, maintaining flexibility to shift cathode chemistries as alternatives mature, and stress-testing business models against cobalt price volatility. For most non-premium applications, cobalt-free options are now commercially viable.

Q: How reliable are "conflict-free" mineral certifications? A: Certifications like the Responsible Minerals Initiative (RMI) and the London Metal Exchange's responsible sourcing framework provide meaningful but imperfect assurance. They certify smelters and refiners rather than individual mine sites, creating traceability gaps in regions with artisanal mining. Blockchain-based traceability pilots from companies like Circulor and Re|Source are improving mine-to-market visibility, but full chain-of-custody verification remains aspirational for most cobalt supply chains.

Q: When will recycling significantly reduce primary mining demand for critical minerals? A: The inflection point is expected between 2035 and 2040, when the first major wave of end-of-life EV batteries reaches recycling facilities at scale. By 2040, the IEA projects recycling could supply 20 to 30% of lithium demand, 30 to 40% of cobalt demand, and 10 to 15% of rare earth demand. Until then, primary extraction remains essential, and companies should focus on designing products for recyclability to capture value when the material becomes available.

Q: Is deep-sea mining likely to become a viable supply source? A: Regulatory and environmental barriers make commercial deep-sea mining unlikely before 2030 at the earliest. The International Seabed Authority's regulatory framework remains incomplete, and mounting scientific opposition increases political risk for early movers. The Metals Company, the most advanced deep-sea mining proponent, still lacks commercial extraction approval. For supply chain planning purposes, deep-sea mining should be treated as a speculative long-term option, not a near-term supply solution.
