The Role of Mining in the EV Battery Supply Chain

Batteries are one of the most important and expensive components of electric vehicles (EVs). The vast majority of EVs use lithium-ion (Li-ion) batteries, which harness the properties of minerals and elements to power the vehicles. But batteries do not grow on trees—the raw materials for them, known as “battery metals”, have to be mined and refined.

The above graphic uses data from BloombergNEF to rank the top 25 countries producing the raw materials for Li-ion batteries.

Battery Metals: The Critical Raw Materials for EV Batteries

The raw materials that batteries use can differ depending on their chemical compositions. However, there are five battery minerals that are considered critical for Li-ion batteries:

• Cobalt
• Graphite
• Lithium
• Manganese
• Nickel

Miners extract these minerals from economically viable deposits and refine them from their raw forms into high-quality products and chemicals for EV batteries.

The Top 25 Nations Supplying Battery Metals

Some countries are more crucial than others to the battery metal supply chain. BloombergNEF ranked the top 25 countries according to the following methodology:

1. First, they tallied the mineral resources, mining capacity, and refining capacity in 2020 and projected commissioned capacity by 2025 for the five key metals listed above in each country.
2. Then, to determine the overall score for each country, BloombergNEF categorized the countries’ capacities into five bands. Countries in the lowest band received a score of 1 and those in the highest band received a score of 5.
3. The overall score is the result of averaging the scores across the five categories for each country.

Now that we have a better understanding of how the rankings work, here are the top 25 nations for raw materials in the Li-ion supply chain in 2020 and 2025.

China’s dominance in the rankings shows that refining capacity is just as important, if not more, as access to raw materials and mining capacity.

China does not boast an abundance of battery metal deposits but ranks first largely due to its control over 80% of global raw material refining capacity. Additionally, China is the world’s largest producer of graphite, the primary anode material for Li-ion batteries.

Australia comes in at number two due to its massive lithium production capacity and nickel reserves. Following Australia is Brazil, one of the world’s top 10 producers of graphite, nickel, manganese, and lithium.

On the other end of the spectrum, Poland, Hungary, Sweden, and Thailand are tied at rank 22. However, it’s important to note that these are among the top 10 countries for cell and component manufacturing—the next step in the lithium-ion battery supply chain.

Countries on the Rise

Sweden’s rank rises five places between 2020 and 2025p, largely due to an expected increase in its mining capacity with nickel and graphite projects in the pipeline. Argentina is projected to jump up to eighth place thanks to its massive lithium resources and multiple mining projects in advanced stages.

Moreover, Japan is projected to move up four places with its first lithium hydroxide refining plant under construction. In addition, Japanese miner Sumitomo Metal Mining is planning to double battery metal production by 2028.

Although China will likely maintain its dominance for the foreseeable future, other countries are ramping up their mining and refining capacities. Given the increasing importance of EVs, it will be interesting to see how the battery metals supply chain evolves going forward.

The Massive Impact of EVs on Commodities

How demand would change in a 100% EV world

The Chart of the Week is a weekly Visual Capitalist feature on Fridays.

What would happen if you flipped a switch, and suddenly every new car that came off assembly lines was electric?

It’s obviously a thought experiment, since right now EVs have close to just 1% market share worldwide. We’re still years away from EVs even hitting double-digit demand on a global basis, and the entire supply chain is built around the internal combustion engine, anyways.

At the same time, however, the scenario is interesting to consider. One recent projection, for example, put EVs at a 16% penetration by 2030 and then 51% by 2040. This could be conservative depending on the changing regulatory environment for manufacturers – after all, big markets like China, France, and the U.K. have recently announced that they plan on banning gas-powered vehicles in the near future.

The Thought Experiment

We discovered this “100% EV world” thought experiment in a UBS report that everyone should read. As a part of their UBS Evidence Lab initiative, they tore down a Chevy Bolt to see exactly what is inside, and then had 39 of the bank’s analysts weigh in on the results.

After breaking down the metals and other materials used in the vehicle, they noticed a considerable amount of variance from what gets used in a standard gas-powered car. It wasn’t just the battery pack that made a difference – it was also the body and the permanent-magnet synchronous motor that had big implications.

As a part of their analysis, they extrapolated the data for a potential scenario where 100% of the world’s auto demand came from Chevy Bolts, instead of the current auto mix.

The Implications

If global demand suddenly flipped in this fashion, here’s what would happen:

Some caveats we think are worth noting:

The Bolt is not a Tesla
The Bolt uses an NMC cathode formulation (nickel, manganese, and cobalt in a 1:1:1 ratio), versus Tesla vehicles which use NCA cathodes (nickel, cobalt, and aluminum, in an estimated 16:3:1 ratio). Further, the Bolt uses an permanent-magnet synchronous motor, which is different from Tesla’s AC induction motor – the key difference there being rare earth usage.

Big Markets, small markets:
Lithium, cobalt, and graphite have tiny markets, and they will explode in size with any notable increase in EV demand. The nickel market, which is more than $20 billion per year, will also more than double in this scenario. It’s also worth noting that the Bolt uses low amounts of nickel in comparison to Tesla cathodes, which are 80% nickel.

Meanwhile, the 100% EV scenario barely impacts the steel market, which is monstrous to begin with. The same can be said for silicon, even though the Bolt uses 6-10x more semiconductors than a regular car. The market for PGMs like platinum and palladium, however, gets decimated in this hypothetical scenario – that’s because their use as catalysts in combustion engines are a primary source of demand.
