TL;DR
A new study indicates that a disruption in cobalt supply at a critical point could cascade through the global EV battery supply chain, causing widespread shortages. Experts warn this vulnerability could threaten the pace of electric vehicle adoption worldwide.
A recent study warns that a disruption in a single point of the cobalt supply chain could trigger widespread failures in the global electric vehicle battery industry, threatening supply security and the pace of energy transition efforts.
The study, conducted by researchers from multiple institutions including the Chinese Academy of Sciences and Peking University, models how shocks in cobalt production—particularly in upstream regions—can cascade through complex international supply networks. Their simulations show that disruptions originating in key mining or refining stages can propagate rapidly, affecting manufacturing and recycling processes worldwide.
Researchers used a multilayer network model to analyze trade flows and production stages across 230 countries, revealing that a single shock can create a domino effect, especially at critical bottlenecks like refining and manufacturing hubs. The analysis indicates that these vulnerabilities are often hidden within the dense interdependencies of the supply chain, making the system more fragile than traditional assessments suggest.
Implications of a Cobalt Supply Shock on Global EV Industry
This research underscores the systemic risks facing the EV battery industry, which relies heavily on cobalt. A major disruption could lead to shortages, delays, and increased costs for electric vehicles worldwide, potentially slowing the transition to cleaner transportation. The findings highlight the need for international cooperation and diversified sourcing strategies to mitigate these risks.

Complex Interconnectedness of Cobalt Supply Chains
The global demand for cobalt has surged due to the rapid growth of electric vehicles and energy storage systems. Historically, supply has been concentrated in a few countries, notably the Democratic Republic of Congo, which accounts for a significant share of global production. Recent disruptions—such as export restrictions, geopolitical tensions, and pandemic-related delays—have exposed vulnerabilities in this concentrated supply chain.
Previous assessments often focused on individual countries or stages of production, but recent research emphasizes the interconnectedness of the entire network. The new model captures how local problems can quickly escalate into global crises, emphasizing the importance of a systemic approach to risk management.
“Our findings reveal that a single disruption in cobalt supply can trigger a chain reaction, impacting the entire EV battery industry worldwide.”

Uncertainties About Future Supply Chain Resilience
It remains unclear how specific geopolitical events or technological developments might alter the vulnerability landscape. The study’s simulations are based on historical data up to 2019, and current or future disruptions could differ in scale or nature. Additionally, the effectiveness of proposed mitigation strategies, such as diversification or stockpiling, is still under assessment.

Next Steps for Industry and Policymakers
Stakeholders are expected to focus on developing more resilient supply chain strategies, including diversifying sources, increasing stockpiles, and enhancing international cooperation. Further research will likely examine real-time monitoring systems and scenario planning to better prepare for potential shocks. Policymakers may also consider implementing regulations to reduce systemic vulnerabilities and promote transparency across the supply chain.

Key Questions
How likely is a cobalt supply disruption to happen?
While specific events cannot be predicted, the study indicates that the supply chain is vulnerable to shocks, especially in concentrated regions. The risk is heightened by geopolitical tensions, trade restrictions, and environmental issues.
Could recycling offset supply risks?
Recycling can help mitigate some supply risks, but current recycling rates are insufficient to fully replace primary cobalt sources. The supply chain remains heavily dependent on mining and refining stages.
What can governments do to reduce this vulnerability?
Governments can promote diversification of sources, support strategic stockpiles, and foster international cooperation to build a more resilient supply chain.
How does this impact the timeline for electric vehicle adoption?
Potential disruptions could cause delays or increase costs for EV production, possibly slowing deployment unless mitigated by strategic planning and diversification efforts.
