Resilient Supply Chains in the Battery Industry: Summary

Executive Summary

Germany's push toward climate goals requires establishing a sustainable and competitive battery value chain by 2030 to lead in electromobility. Despite significant battery cell manufacturing capacities in Europe, raw material dependency is high—Europe relies heavily on imports due to limited domestic mining and geopolitical tensions. Recycling and diversification are crucial for long-term resilience.

Key Findings

1. Supply Chain Vulnerabilities

• Battery supply chains are complex and concentrated in regions like Asia (China dominates key materials).
• Geopolitical risks, trade conflicts, and resource concentration (e.g., China in refining, Bolivia in lithium) threaten supply security.
• Demand for batteries is rising rapidly; global lithium-ion battery market value is projected at ~$42 billion with a 20% annual growth by 2030.

2. Raw Materials Overview

• Lithium: Europe imports over 90% of its lithium. Demand could multiply by 21× by 2030.
• Nickel, Manganese, Cobalt, Graphite: Supply is concentrated in specific regions (e.g., China for refining), leading to bottlenecks during disruptions. Cobalt and graphite face high geopolitical risks.
• Efforts to reduce material dependency include lithium substitution in anodes, but cobalt remains critical.

3. European Resilience Measures

• Self-Sufficiency: Limited to ~25% for lithium and 45% for manganese. Europe must import ~80% for nickel and cobalt.
• Digitalization & Transparency: Using digital product passports and AI for demand forecasting.
• Recycling: Returns of used traction batteries (estimated 300,000 tons by 2030) can supplement raw material supply.
• Diversification: States supply chains by diversifying suppliers and investing in new European production sites.

4. Risks & Mitigation

• Geopolitical: Trade wars, sanctions, and dominance by China exacerbate risks.
• Strategic: Value-added steps (pCAM, CAM, AAM) are under capacity, creating risks in Europe.
• Measures include strategic partnerships, commodity hedging, and long-term contracts.

Conclusions

Achieving sustainable and resilient supply chains requires a combination of diversification, recycling, and strategic partnerships. Battery raw material supply chains are susceptible to geopolitical and trade disruptions. Resilience must be built progressively with transparency initiatives, partnerships with raw material-rich countries, and circular economy principles.
