One country refines roughly 60% of the world's lithium and close to 70% of its cobalt, and the EV battery ETF sitting in a retail portfolio has no line item that says so. That fund can hold forty names spread across six countries, from a lithium miner in Western Australia to an automaker in Michigan, and still route back to the same handful of Chinese refiners underneath every one of them. The fund tracks an industry, not a mineral flow, and that's exactly where the risk hides. So what is an investor paying 0.50% to 0.75% a year in fees actually buying diversification from?
The clean energy transition needs cobalt, graphite, lithium, manganese, and nickel in volumes that didn't exist in any supply chain a decade ago. That part of the story gets told constantly. What gets told less often: the market structure for these five minerals isn't a competitive commodity market the way oil or copper roughly are. It's a set of chokepoints, controlled by a small number of state owned or state aligned refiners, sitting downstream of mining operations that are themselves crammed into a handful of countries. The biggest unpriced risk in EV investing right now isn't battery chemistry or charging infrastructure. It's that retail products marketed as diversified clean energy exposure are quietly exposed to single country refining chokepoints that can reprice overnight on export policy alone.
This isn't theoretical. Indonesia's nickel export restrictions, first imposed in 2020 and tightened since, reshaped global nickel pricing within two years. China's periodic graphite export licensing requirements, expanded in late 2023, already forced battery makers outside China to requalify supply chains mid contract. These aren't black swan events. They're structural features of how these five markets are built, and they recur on a schedule close to predictable. Here's where these chokepoints actually sit, mineral by mineral, before we get into how they reach fund holdings.
Mapping Where the Chokepoints Actually Sit
Mining vs Refining Concentration by Mineral
| Mineral | Top Mining Source | Refining Chokepoint |
|---|---|---|
| Cobalt | DR Congo, ~75% mined | China, most refining |
| Lithium | Australia, Chile, Argentina, US | China, ~60% refining |
| Nickel | Indonesia, ~60% mined | China financed smelting |
| Graphite | China, dominant mining | China, natural and synthetic |
| Manganese | South Africa, Gabon, Australia | China, concentrated processing |

Start with cobalt. The Democratic Republic of Congo accounts for roughly 75% of global mined cobalt supply, a figure that has held steady for years despite constant talk of diversification. But mining share only tells half the story. China controls most of global cobalt refining capacity, so Congolese ore frequently travels to Chinese refiners before it ever reaches a battery cell manufacturer. An investor holding a cobalt miner listed in Toronto or London is still exposed to a refining bottleneck six thousand miles away.
Lithium looks more geographically distributed on the mining side, split across Australia, Chile, Argentina, and increasingly the United States. The refining picture tells a different story. China processes most of the world's lithium into battery grade material, though the exact share shifts depending on whether you count lithium carbonate, lithium hydroxide, or both. Albemarle, the largest listed lithium producer in the world, still routes meaningful volumes through Chinese conversion facilities for certain product grades. Scale doesn't remove a company from the chokepoint.
Nickel and graphite complete the picture, and each has its own concentration story. Indonesia went from a marginal nickel producer a decade ago to supplying around 60% of global mined nickel today, largely through Chinese financed smelting capacity built inside the country. Natural graphite mining is dominated by China, which also controls most synthetic graphite production, the form increasingly preferred for battery anodes because of its purity and consistency. Manganese, the quiet fifth mineral, gets less attention but is mined predominantly in South Africa, Gabon, and Australia, with processing again concentrated in China. Five minerals, five different geological footprints, and nearly all of them funnel toward one recurring processing destination. The next step is tracing how that pattern turns into price moves inside the funds built on top of it.

Clean energy and EV themed ETFs, including widely held products like Global X's Lithium and Battery Tech ETF and iShares' Global Clean Energy ETF, hold baskets of mining and battery supply chain equities. These funds track an industry, not a mineral flow, and that distinction matters more than it sounds like it should. A fund can hold shares in a lithium miner in Western Australia, a battery cell maker in South Korea, and an automaker in Michigan, and still carry a common, undisclosed exposure to Chinese refining capacity sitting underneath all three.
Export policy is the mechanism that turns this structural concentration into price volatility. When Indonesia restricted raw nickel ore exports to force domestic smelting investment, nickel prices spiked, then collapsed as Indonesian smelting capacity came online faster than demand could absorb it, pushing nickel into oversupply by 2023 and 2024. China's late 2023 graphite export licensing rules didn't ban exports outright, but added approval friction that delayed shipments for weeks at a time, which is its own form of cost. Neither event showed up as a line item in any fund prospectus. Both moved the underlying economics of companies those funds hold.
Carbon price exposure compounds this. Refining these minerals, especially nickel and lithium conversion, is energy intensive, and a meaningful share of Chinese and Indonesian processing capacity still runs on coal fired power. As the European Union's Carbon Border Adjustment Mechanism phases in fully by 2026, battery components refined using high carbon processes face a widening cost disadvantage against lower carbon alternatives, a dynamic barely reflected in current battery mineral pricing. The policy risk here is layered: export policy, trade friction, and carbon accounting all press on the same narrow set of refining assets at once. If the fund structure can't see any of this, what exactly is the fund investor paying 0.50% to 0.75% a year to access? That question is what makes the alternatives worth examining directly.

Government responses to this concentration are real and partially investable, though smaller in scale than the headlines around them suggest. The US Inflation Reduction Act's critical minerals provisions, the EU's Critical Raw Materials Act targeting 10% domestic extraction and 40% domestic processing of strategic raw materials by 2030, and bilateral minerals agreements between the US and countries like Australia and Japan are all attempts to build refining capacity outside the dominant chokepoints. None of them have changed the processing concentration figures in any material way as of this writing. Policy intent and built capacity are running on very different timelines, often five to ten years apart.
Recycling is the diversification story with the most underappreciated upside, and also the most overstated near term scale. Companies like Redwood Materials and Li Cycle are building battery recycling capacity in North America specifically to create a mineral supply chain that bypasses both the mining concentration and the refining chokepoint at once. The economics improve as the EV fleet ages, since a car sold in 2021 doesn't generate recyclable battery material until it's retired roughly eight to fifteen years later. Recycled supply as a share of total battery mineral demand sits in the low single digits globally today, and will stay there for most of this decade regardless of how much capital flows into the sector. That gap between narrative and near term volume inflates valuations on recycling stocks ahead of actual throughput.
For the retail investor, the honest takeaway is less about picking the right mineral and more about recognizing what a fund's holdings list can't show you. A battery ETF with forty names spread across six countries can still carry a single point of failure if most of those forty names depend on the same three refining complexes. Diversification by equity ticker isn't the same thing as diversification by supply chain, and fund marketing material built around the word "diversified" conflates the two constantly. That gap is the answer to the question this post opened with: a 0.50% to 0.75% expense ratio buys exposure to an industry's equity structure, not protection from the mineral chokepoints underneath it. Three practical paths exist right now: direct exposure to a miner outside the dominant refining geography, a basket of recyclers still years from scale, or simply sizing EV supply chain exposure smaller than the sector's growth narrative suggests. Each carries its own timeline mismatch against the five to ten year horizon policymakers are actually working on.
