The Key Minerals in an EV Battery
Breaking Down the Key Minerals in an EV Battery
Inside practically every electric vehicle (EV) is a lithium-ion battery that depends on several key minerals that help power it.
Some minerals make up intricate parts within the cell to ensure the flow of electrical current. Others protect it from accidental damage on the outside.
This infographic uses data from the European Federation for Transport and Environment to break down the key minerals in an EV battery. The mineral content is based on the ‘average 2020 battery’, which refers to the weighted average of battery chemistries on the market in 2020.
The Battery Minerals Mix
The cells in the average battery with a 60 kilowatt-hour (kWh) capacity—the same size that’s used in a Chevy Bolt—contained roughly 185 kilograms of minerals. This figure excludes materials in the electrolyte, binder, separator, and battery pack casing.
Mineral | Cell Part | Amount Contained in the Avg. 2020 Battery (kg) | % of Total |
---|---|---|---|
Graphite | Anode | 52kg | 28.1% |
Aluminum | Cathode, Casing, Current collectors | 35kg | 18.9% |
Nickel | Cathode | 29kg | 15.7% |
Copper | Current collectors | 20kg | 10.8% |
Steel | Casing | 20kg | 10.8% |
Manganese | Cathode | 10kg | 5.4% |
Cobalt | Cathode | 8kg | 4.3% |
Lithium | Cathode | 6kg | 3.2% |
Iron | Cathode | 5kg | 2.7% |
Total | N/A | 185kg | 100% |
The cathode contains the widest variety of minerals and is arguably the most important and expensive component of the battery. The composition of the cathode is a major determinant in the performance of the battery, with each mineral offering a unique benefit.
For example, NMC batteries, which accounted for 72% of batteries used in EVs in 2020 (excluding China), have a cathode composed of nickel, manganese, and cobalt along with lithium. The higher nickel content in these batteries tends to increase their energy density or the amount of energy stored per unit of volume, increasing the driving range of the EV. Cobalt and manganese often act as stabilizers in NMC batteries, improving their safety.
Altogether, materials in the cathode account for 31.3% of the mineral weight in the average battery produced in 2020. This figure doesn’t include aluminum, which is used in nickel-cobalt-aluminum (NCA) cathode chemistries, but is also used elsewhere in the battery for casing and current collectors.
Meanwhile, graphite has been the go-to material for anodes due to its relatively low cost, abundance, and long cycle life. Since the entire anode is made up of graphite, it’s the single-largest mineral component of the battery. Other materials include steel in the casing that protects the cell from external damage, along with copper, used as the current collector for the anode.
Minerals Bonded by Chemistry
There are several types of lithium-ion batteries with different compositions of cathode minerals. Their names typically allude to their mineral breakdown.
For example:
- NMC811 batteries cathode composition:
80% nickel
10% manganese
10% cobalt - NMC523 batteries cathode composition:
50% nickel
20% manganese
30% cobalt
Here’s how the mineral contents differ for various battery chemistries with a 60kWh capacity:
With consumers looking for higher-range EVs that do not need frequent recharging, nickel-rich cathodes have become commonplace. In fact, nickel-based chemistries accounted for 80% of the battery capacity deployed in new plug-in EVs in 2021.
Lithium iron phosphate (LFP) batteries do not use any nickel and typically offer lower energy densities at better value. Unlike nickel-based batteries that use lithium hydroxide compounds in the cathode, LFP batteries use lithium carbonate, which is a cheaper alternative. Tesla recently joined several Chinese automakers in using LFP cathodes for standard-range cars, driving the price of lithium carbonate to record highs.
The EV battery market is still in its early hours, with plenty of growth on the horizon. Battery chemistries are constantly evolving, and as automakers come up with new models with different characteristics, it’ll be interesting to see which new cathodes come around the block.

Ranked: The Top 10 EV Battery Manufacturers in 2023
Asia dominates this ranking of the world’s largest EV battery manufacturers in 2023.
The Top 10 EV Battery Manufacturers in 2023

Despite efforts from the U.S. and EU to secure local domestic supply, all major EV battery manufacturers remain based in Asia.
In this graphic we rank the top 10 EV battery manufacturers by total battery deployment (measured in megawatt-hours) in 2023. The data is from EV Volumes.
Chinese Dominance
Contemporary Amperex Technology Co. Limited (CATL) has swiftly risen in less than a decade to claim the title of the largest global battery group.
The Chinese company now has a 34% share of the market and supplies batteries to a range of made-in-China vehicles, including the Tesla Model Y, SAIC’s MG4/Mulan, and Li Auto models.
Company | Country | 2023 Production (megawatt-hour) | Share of Total Production |
---|---|---|---|
CATL | 🇨🇳China | 242,700 | 34% |
BYD | 🇨🇳China | 115,917 | 16% |
LG Energy Solution | 🇰🇷Korea | 108,487 | 15% |
Panasonic | 🇯🇵Japan | 56,560 | 8% |
SK On | 🇰🇷Korea | 40,711 | 6% |
Samsung SDI | 🇰🇷Korea | 35,703 | 5% |
CALB | 🇨🇳China | 23,493 | 3% |
Farasis Energy | 🇨🇳China | 16,527 | 2% |
Envision AESC | 🇨🇳China | 8,342 | 1% |
Sunwoda | 🇨🇳China | 6,979 | 1% |
Other | - | 56,040 | 8% |
In 2023, BYD surpassed LG Energy Solution to claim second place. This was driven by demand from its own models and growth in third-party deals, including providing batteries for the made-in-Germany Tesla Model Y, Toyota bZ3, Changan UNI-V, Venucia V-Online, as well as several Haval and FAW models.
The top three battery makers (CATL, BYD, LG) collectively account for two-thirds (66%) of total battery deployment.
Once a leader in the EV battery business, Panasonic now holds the fourth position with an 8% market share, down from 9% last year. With its main client, Tesla, now effectively sourcing batteries from multiple suppliers, the Japanese battery maker seems to be losing its competitive edge in the industry.
Overall, the global EV battery market size is projected to grow from $49 billion in 2022 to $98 billion by 2029, according to Fortune Business Insights.

White Gold: Mapping U.S. Lithium Mines
In this graphic, Visual Capitalist partnerered with EnergyX to explore the size and location of U.S. lithium mines.
White Gold: Mapping U.S. Lithium Mines
The U.S. doubled imports of lithium-ion batteries for the third consecutive year in 2022, and with EV demand growing yearly, U.S. lithium mines must ramp up production or rely on other nations for their supply of refined lithium.
To determine if the domestic U.S. lithium opportunity can meet demand, we partnered with EnergyX to determine how much lithium sits within U.S. borders.
U.S. Lithium Projects
The most crucial measure of a lithium mine’s potential is the quantity that can be extracted from the source.
For each lithium resource, the potential volume of lithium carbonate equivalent (LCE) was calculated with a ratio of one metric ton of lithium producing 5.32 metric tons of LCE. Cumulatively, existing U.S. lithium projects contain 94.8 million metric tons of LCE.
Rank | Project Name | LCE, million metric tons (est.) |
---|---|---|
1 | McDermitt Caldera | 21.5 |
2 | Thacker Pass | 19.1 |
3 | Tonopah Flats | 18.0 |
4 | TLC Lithium | 10.7 |
5 | Clayton Valley (Century Lithium) | 6.3 |
6 | Zeus Lithium | 6.3 |
7 | Rhyolite Ridge | 3.4 |
8 | Arkansas Smackover (Phase 1A) | 2.8 |
9 | Basin Project | 2.2 |
10 | McGee Deposit | 2.1 |
11 | Arkansas Smackover (South West) | 1.8 |
12 | Clayton Valley (Lithium-X, Pure Energy) | 0.8 |
13 | Big Sandy | 0.3 |
14 | Imperial Valley/Salton Sea | 0.3 |
U.S. Lithium Opportunities, By State
U.S. lithium projects mainly exist in western states, with comparatively minor opportunities in central or eastern states.
State | LCE, million metric tons (est.) |
---|---|
Nevada | 88.2 |
Arkansas | 4.6 |
Arizona | 2.5 |
California | 0.3 |
Currently, the U.S. is sitting on a wealth of lithium that it is underutilizing. For context, in 2022, the U.S. only produced about 5,000 metric tons of LCE and imported a projected 19,000 metric tons of LCE, showing that the demand for the mineral is healthy.
The Next Gold Rush?
U.S. lithium companies have the opportunity to become global leaders in lithium production and accelerate the transition to sustainable energy sources. This is particularly important as the demand for lithium is increasing every year.
EnergyX is on a mission to meet U.S. lithium demands using groundbreaking technology that can extract 300% more lithium from a source than traditional methods.
You can take advantage of this opportunity by investing in EnergyX and joining other significant players like GM in becoming a shareholder.
