Fluorine: The Overlooked Battery Material China Already Dominates

Highlights

• China produced roughly 60% of global fluorspar in 2025, with China, Mexico, South Africa and Mongolia controlling 77% of reserves.
• Fluorinated chemicals are essential to battery electrolytes, binders, additives and separators, improving stability, safety and cycle life.
• The real risk is downstream: Western nations may own fluorspar deposits but still depend on China for purification and specialty fluorochemical conversion.
• Analysts warn this mirrors the rare earth mistake—counting raw resources while overlooking industrial processing capability.
• Some fluorinated battery materials raise PFAS and environmental concerns, adding regulatory complexity to supply chain planning.
