Summary: The global cobalt supply chain is more interconnected—and more vulnerable—than previously thought, with disruptions capable of triggering far-reaching cascades across multiple countries and industries. Researchers warn that protecting battery supply chains will require system-wide coordination because critical bottlenecks can turn local shocks into global problems.
Cobalt is a critical ingredient in lithium-ion batteries used in electric vehicles and energy storage systems, but new research suggests the global cobalt supply chain may be far more vulnerable than previously recognized. Rather than being limited to isolated shortages, disruptions in one country or production stage can spread through the network, triggering cascading failures across multiple regions and industries.
By combining material flow analysis with a multilayer shock propagation model, researchers found that risks often originate in upstream parts of the supply chain but become most severe at key refining and manufacturing bottlenecks. The study shows that shocks can move through both horizontal and vertical pathways, as well as through direct and indirect connections, creating long chains of disruption and sudden breakdowns. These findings suggest that traditional country-by-country risk assessments fail to capture the full extent of the cobalt supply chain's vulnerability and that coordinated system-wide strategies are needed to strengthen resilience.
