Cobalt
Transition Metal
Last updated: January 2026Overview
A transition metal critical for lithium-ion battery cathodes, aerospace superalloys, and tool steels. The DRC produces 70% of global supply, creating significant concentration risk.
Strategic Relevance
Essential for high-energy-density batteries (NMC/NCA). LFP alternatives are gaining share but cobalt remains critical for premium EV and aerospace applications.
