Critical Minerals and Components for Electric Vehicles

Electric vehicles swap the fuel tank for a battery and the combustion engine for an electric motor, and both changes multiply a car's appetite for critical minerals. A battery pack concentrates lithium, nickel, cobalt, manganese and graphite in a single component, while the motor relies on rare earth permanent magnets in most designs, and the car as a whole carries several times the copper of a petrol model.

The rest of the vehicle draws on a wider list still. Aluminum and magnesium shed weight to stretch range, silicon carbide and gallium nitride chips manage power between battery and motor, and niobium and vanadium strengthen the steel of the body. A small lead-acid battery often still powers the auxiliary systems.

That combination makes electric vehicles one of the main forces reshaping critical mineral markets, and one of the most exposed to supply concentrated in a few countries. Stockatomics maps 57 critical minerals to electric vehicles.

An electric vehicle needs critical minerals for its battery, its motor, its electronics and its body, and the battery alone accounts for most of the difference from a petrol car.

Battery

The cathode is the biggest mineral decision a carmaker makes. Nickel-rich chemistries use lithium, nickel, manganese and cobalt to maximise range, while lithium iron phosphate uses lithium, iron and phosphate to cut cost and avoid nickel and cobalt. Almost every cell uses a graphite anode, increasingly blended with silicon, current collectors of aluminum and copper, and an electrolyte and binder built on fluorspar.

Motor

Most electric vehicles use permanent-magnet motors, whose magnets combine neodymium and praseodymium with boron, plus dysprosium or terbium so they keep their strength when the motor runs hot. The windings are copper.

Power electronics and wiring

Inverters and chargers use silicon carbide and gallium nitride chips to convert power with less waste, while copper wiring runs throughout the car. Tantalum capacitors and tin solder hold the electronics together.

Body and chassis

To offset the weight of the battery, carmakers use more aluminum and magnesium, and high-strength steels made with niobium, vanadium and manganese, galvanised with zinc.

The electric vehicle supply chain runs through China at almost every step. Chinese companies refine most of the world's lithium, cobalt and graphite, make most battery cells and produce most rare earth magnets. The Democratic Republic of Congo mines most of the world's cobalt, and Indonesia now supplies most new nickel, much of it through Chinese-owned plants.

China has added graphite and several rare earths to its export controls, and in 2025 carmakers in the US, Europe and Japan faced shortages of rare earth magnets that briefly halted some production lines.

What that means for carmakers

• Western carmakers are signing direct deals with mines and refiners, and investing in them
• US and European rules increasingly reward batteries and minerals sourced outside China
• Battery chemistry and motor design are being chosen partly to reduce exposure to the scarcest minerals

As of October 2026, the electric vehicle market is growing unevenly. China leads by a wide margin, Europe continues under tight emissions rules, and the United States has slowed after the end of the federal electric vehicle tax credit in 2025.

What to watch

• Chemistry shifts: lithium iron phosphate has taken a large share of the market, reducing nickel and cobalt per vehicle, while sodium-ion is being commercialised for cheaper cars
• Magnet risk: after the 2025 shortages, carmakers are qualifying non-Chinese magnet suppliers and testing motors that need fewer or no heavy rare earths
• Sourcing rules: US and European rules increasingly reward minerals and batteries sourced outside China
• Hybrids: a renewed rise in hybrids adds battery demand while keeping some demand for platinum group metals in exhaust catalysts
• Recycling: the first large wave of end-of-life batteries is approaching, creating a new source of lithium, nickel and cobalt
