Battery supply chains and traceability

Why it matters

The EU Batteries Regulation introduces due-diligence, carbon-footprint and recycled-content requirements, together with a digital battery passport for electric-vehicle and industrial batteries. Traceability across complex mineral supply chains is becoming a regulatory and commercial requirement.

Traceability depends on suppliers sharing reliable data across several tiers, often in different countries. Carmakers and battery makers are working with suppliers and industry initiatives to agree data standards and verification methods.

What's changing

• Battery passports will require detailed information on materials, origin and performance.
• Due-diligence obligations cover risks in sourcing cobalt, lithium, nickel and natural graphite.
• Carmakers are diversifying sources and investing in recycling.

How leaders are responding

• Mapping suppliers beyond tier one to the source of critical minerals.
• Piloting data-sharing platforms for battery passport information.
• Building recycling and second-life partnerships.

What good looks like

• Traceability data collected from mine to cell for each battery model
• Recycled-content sourcing contracts signed well before 2031
• Passport data maintained by one owner with supplier inputs automated

What to watch

• Phased requirements of the EU Batteries Regulation.
• Development of battery passport data standards.
• Investment in European recycling capacity.
