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.

ManganeseCathode10kg5.4%
CobaltCathode8kg4.3%
LithiumCathode6kg3.2%
IronCathode5kg2.7%
TotalN/A185kg100%

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:

battery minerals by chemistry

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.

Charted: The Energy Demand of U.S. Data Centers

Data center power needs are projected to triple by 2030.

Charted: The Energy Demand of U.S. Data Centers

This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.

As the digital economy accelerates and generative AI becomes more deeply embedded in business and daily life, the physical infrastructure supporting these technologies is undergoing a transformative explosion.

In this graphic, we use data from McKinsey to show current and projected energy demand from data centers in the United States. Data is from October 2023.

U.S. Data Centers Could Quadruple Power Demand by 2030

Today, data centers account for roughly 4% of total U.S. electricity consumption. But by 2030, that share is projected to rise to 12%, driven by unprecedented growth in computing power, storage needs, and AI model training.

In fact, U.S. data center energy demand is set to jump from 224 terawatt-hours in 2025 to 606 terawatt-hours in 2030.

YearConsumption (TWh)% of Total Power Demand
20231474%
20241784%
20252245%
20262927%
20273718%
20284509%
202951310%
203060612%

Meeting this projected demand could require $500 billion in new data center infrastructure, along with a vast expansion of electricity generation, grid capacity, and water-cooling systems. Generative AI alone could require 50–60 GW of additional infrastructure.

This massive investment would also depend on upgrades in permitting, land use, and supply chain logistics. For example, the lead time to power new data centers in large markets such as Northern Virginia can exceed three years. In some cases, lead times for electrical equipment are two years or more.

A Strain on the U.S. Grid

The U.S. has experienced relatively flat power demand since 2007. Models suggest that this stability could be disrupted in the coming years. Data center growth alone could account for 30–40% of all net-new electricity demand through 2030.

Unlike typical power loads, data center demand is constant, dense, and growing exponentially. Facilities often operate 24/7, with little downtime and minimal flexibility to reduce usage.

Visualizing China’s Battery Recycling Dominance

In 2025, China will hold 78% of pre-treatment and 89% of refining capacity.

Visualizing China’s Battery Recycling Dominance

Battery recycling is expected to become a cornerstone of the global energy transition as electric vehicles (EVs) and other battery-powered technologies become more widespread.

According to exclusive data from Benchmark Mineral Intelligence, China holds a dominant position in both the pre-treatment and refining stages of battery recycling.

Chinese Growing Dominance

Battery recycling involves two major stages. First is pre-treatment, where recycling begins. Scrap batteries are typically shredded and separated to produce a material known as black mass.

The next stage is refining, which processes black mass into valuable lithium-, nickel-, and cobalt-based chemicals for use in battery cathodes.

China’s scale, infrastructure, and early investments in battery supply chains have translated into an outsized advantage in recycling capacity.

As the largest producer and user of lithium ion batteries, the country is expected to process 3.6 million tonnes of scrap batteries in 2025, up from 1.2 million tonnes in 2022. This would account for 78% of global pre-treatment capacity, with total global capacity projected to exceed 4.6 million tonnes.

In second place is the rest of Asia, with 361,000 tonnes, followed by Europe with 416,000 tonnes. While the U.S. attempts to reduce its reliance on China in the mineral sector, North America accounts for just 196,000 tonnes.

The refining stage is even more concentrated.

China’s black mass refining capacity is projected to nearly triple, from 895,000 tonnes in 2022 to 2.5 million tonnes by 2025—representing 89% of global capacity.

Refining is critical, as it converts recycled material into high-purity, battery-grade chemicals. The rest of Asia is expected to refine 225,000 tonnes, Europe 28,000 tonnes, and North America only 21,000 tonnes. Between 2022 and 2025, China’s refining capacity is projected to grow by 179%, while North America’s is expected to surge by 425%—albeit from a much smaller base.

As global demand for EVs and battery storage rises, countries looking to build domestic recycling infrastructure must accelerate investment to reduce dependence on Chinese supply chains.
