			Why it constrains
Lithium-ion battery cells	Component	High	China produced 80% of global battery cells and over 90% of anode material in 2024 (IEA). CATL and other Chinese battery makers are on DoD's 1260H list, and China's October 2025 controls on high-energy-density cells (suspended to November 2026) target the cells drones use.

Criticality is how much a shortage would constrain production; open an input for producers, concentration and trade controls.
