Visualizing the Decline of Copper Usage in EVs

Copper intensity in passenger battery electric vehicles (BEVs) has steadily decreased over the last decade, driven by numerous technological advancements alongside increasing usage of alternative materials such as aluminum.

In this graphic, we visualize the evolution of copper demand in various subcomponents of passenger battery electric vehicles (BEVs) from 2015 to 2030F, along with total global copper demand driven by EVs for the same period. This data comes exclusively from Benchmark Mineral Intelligence.

Copper Intensity Per Car

According to Benchmark Mineral Intelligence, the copper intensity per vehicle is expected to decline by almost 38 kg, from 99 kg in 2015 to 62 kg by 2030.

One of the most significant factors driving this decline is thrifting, where engineers and manufacturers continuously improve the efficiency and performance of various components, leading to reduced copper usage. A key example of this is in battery production, where the thickness of copper foil used in battery anodes has significantly decreased.

In 2015, Benchmark estimated copper foil usage was just over 41 kg per vehicle (at an average thickness of 10 microns), but by 2030, it is projected to fall to 26 kg as manufacturers continue to adopt thinner foils.

Similarly, automotive wiring systems have become more localized, with advances in high-voltage wiring and modular integration allowing for reduced copper content in wiring harnesses.

Copper used in wiring has dropped from 30 kg per vehicle in 2015 to a projected 17 kg by 2030.

Newer, more compact power electronics and improved thermal management in motors and charging cables have also contributed to the reduction in copper usage.

Substitution has also played a role, with alternatives such as aluminum increasingly being used in components like busbars, wiring harnesses, and charging cable applications.

Aluminum’s lighter weight and lower cost have made it a practical alternative to copper in specific applications, though the additional space required to achieve the same level of conductivity can limit its use in certain cases.

Benchmark estimates that copper used in automotive wire harnesses has declined by 30% between 2015 and 2024.

The Road Ahead

Despite reductions in per-vehicle copper usage, the outlook for copper demand from the EV sector remains strong due to the sector’s growth.

Benchmark’s analysis indicates that by 2030, copper demand driven by EVs alone will exceed 2.5 million tonnes, securing copper’s critical role in the transition to a low-carbon future.

Visualizing China’s Cobalt Supply Dominance by 2030

Chinese dominance over critical minerals used in technologies like smartphones, electric vehicles (EVs), and solar power has become a growing concern for the U.S. and other Western countries.

Currently, China refines 68% of the world’s nickel, 40% of copper, 59% of lithium, and 73% of cobalt, and is continuing to expand its mining operations.

This graphic visualizes the total cobalt supply from the top 10 producers in 2030, highlighting China’s dominance. The data comes from Benchmark Mineral Intelligence, as of July 2024.

China’s Footprint in Africa

Cobalt is a critical mineral with a wide range of commercial, industrial, and military applications. It has gained significant attention in recent years due to its use in battery production. Today, the EV sector accounts for 40% of the global cobalt market.

The Democratic Republic of Congo (DRC) currently produces 74% of the world’s cobalt supply. Although cobalt deposits exist in regions like Australia, Europe, and Asia, the DRC holds the largest reserves by far.

China is the world’s leading consumer of cobalt, with nearly 87% of its cobalt consumption dedicated to the lithium-ion battery industry.

Although Chinese companies hold stakes in only three of the top 10 cobalt-producing countries, they control over half of the cobalt production in the DRC and Indonesia, and 85% of the output in Papua New Guinea.

Given the DRC’s large share of global cobalt production, many Chinese companies have expanded their presence in the country, acquiring projects and forming partnerships with the Congolese government.

According to Benchmark, Chinese companies are expected to control 46% of the global cobalt mined supply by 2030, a 3% increase from 2023.

By 2030, the top 10 cobalt-producing countries will account for 96% of the total mined supply, with just two countries—the DRC and Indonesia—contributing 84% of the total.
