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.

How EV Adoption Will Impact Oil Consumption (2015-2025P)
How much oil is saved by adding electric vehicles into the mix? We look at data from 2015 to 2025P for different types of EVs.

The EV Impact on Oil Consumption
As the world moves towards the electrification of the transportation sector, demand for oil will be replaced by demand for electricity.
To highlight the EV impact on oil consumption, the above infographic shows how much oil has been and will be saved every day between 2015 and 2025 by various types of electric vehicles, according to BloombergNEF.
How Much Oil Do Electric Vehicles Save?
A standard combustion engine passenger vehicle in the U.S. uses about 10 barrels of oil equivalent (BOE) per year. A motorcycle uses 1, a Class 8 truck about 244, and a bus uses more than 276 BOEs per year.
When these vehicles become electrified, the oil their combustion engine counterparts would have used is no longer needed, displacing oil demand with electricity.
Since 2015, two and three-wheeled vehicles, such as mopeds, scooters, and motorcycles, have accounted for most of the oil saved from EVs on a global scale. With a wide adoption in Asia specifically, these vehicles displaced the demand for almost 675,000 barrels of oil per day in 2015. By 2021, this number had quickly grown to 1 million barrels per day.
Let’s take a look at the daily displacement of oil demand by EV segment.
Number of barrels saved per day, 2015 | Number of barrels saved per day, 2025P | |
---|---|---|
Electric Passenger Vehicles | 8,600 | 886,700 |
Electric Commercial Vehicles | 0 | 145,000 |
Electric Buses | 43,100 | 333,800 |
Electric Two & Three-Wheelers | 674,300 | 1,100,000 |
Total Oil Barrels Per Day | 726,000 | 2,465,500 |
Today, while work is being done in the commercial vehicle segment, very few large trucks on the road are electric—however, this is expected to change by 2025.
Meanwile, electric passenger vehicles have shown the biggest growth in adoption since 2015.
In 2022, the electric car market experienced exponential growth, with sales exceeding 10 million cars. The market is expected to continue its strong growth throughout 2023 and beyond, eventually coming to save a predicted 886,700 barrels of oil per day in 2025.
From Gas to Electric
While the world shifts from fossil fuels to electricity, BloombergNEF predicts that the decline in oil demand does not necessarily equate to a drop in oil prices.
In the event that investments in new supply capacity decrease more rapidly than demand, oil prices could still remain unstable and high.
The shift toward electrification, however, will likely have other implications.
While most of us associate electric vehicles with lower emissions, it’s good to consider that they are only as sustainable as the electricity used to charge them. The shift toward electrification, then, presents an incredible opportunity to meet the growing demand for electricity with clean energy sources, such as wind, solar and nuclear power.
The shift away from fossil fuels in road transport will also require expanded infrastructure. EV charging stations, expanded transmission capacity, and battery storage will likely all be key to supporting the wide-scale transition from gas to electricity.

Graphite: An Essential Material in the Battery Supply Chain
Graphite represents almost 50% of the materials needed for batteries by weight, no matter the chemistry.

Graphite: An Essential Material in the Battery Supply Chain
The demand for lithium-ion (Li-ion) batteries has skyrocketed in recent years due to the increasing popularity of electric vehicles (EVs) and renewable energy storage systems.
What many people don’t realize, however, is that the key component of these batteries is not just lithium, but also graphite.
Graphite represents almost 50% of the materials needed for batteries by weight, regardless of the chemistry. In Li-ion batteries specifically, graphite makes up the anode, which is the negative electrode responsible for storing and releasing electrons during the charging and discharging process.
To explore just how essential graphite is in the battery supply chain, this infographic sponsored by Northern Graphite dives into how the anode of a Li-ion battery is made.
What is Graphite?
Graphite is a naturally occurring form of carbon that is used in a wide range of industrial applications, including in synthetic diamonds, EV Li-ion batteries, pencils, lubricants, and semiconductor substrates.
It is stable, high-performing, and reusable. While it comes in many different grades and forms, battery-grade graphite falls into one of two classes: natural or synthetic.
Natural graphite is produced by mining naturally occurring mineral deposits. This method produces only one to two kilograms of CO2 emissions per kilogram of graphite.
Synthetic graphite, on the other hand, is produced by the treatment of petroleum coke and coal tar, producing nearly 5 kg of CO2 per kilogram of graphite along with other harmful emissions such as sulfur oxide and nitrogen oxide.
A Closer Look: How Graphite Turns into a Li-ion Battery Anode
The battery anode production process is composed of four overarching steps. These are:
- Mining
- Shaping
- Purifying
- Coating
Each of these stages results in various forms of graphite with different end-uses.
For instance, the micronized graphite that results from the shaping process can be used in plastic additives. On the other hand, only coated spherical purified graphite that went through all four of the above stages can be used in EV Li-ion batteries.
The Graphite Supply Chain
Despite its growing use in the energy transition all around the world, around 70% of the world’s graphite currently comes from China.
With scarce alternatives to be used in batteries, however, achieving supply security in North America is crucial, and it is using more environmentally friendly approaches to graphite processing.
With a lower environmental footprint and lower production costs, natural graphite serves as the anode material for a greener future.
