Fusion-grade lithium refers to isotopically tailored materials that support peaceful nuclear fusion energy research and development.

Lithium exists in two stable isotopes: lithium-6 (Li-6) and lithium-7 (Li-7). They are chemically identical but differ slightly in atomic weight. In nature, lithium is about 7.6% Li-6 and 92.4% Li-7. For advanced fusion applications, this natural ratio is not sufficient — each isotope may be enriched to higher purity depending on its role in energy systems.

Global fusion research projects — such as ITER and emerging private-sector programs — anticipate significant demand for isotopically precise lithium to support tritium breeding and plasma control in a safe, transparent, and peaceful context. In this setting, extremely high isotopic and chemical purity is vital, since even trace contaminants or off-spec isotopic ratios could disrupt reactor operation or damage plasma-facing components.

As the world seeks reliable, carbon-free energy, fusion-grade lithium provides one of the essential building blocks for tomorrow’s clean energy future.
