Nuclear fusion fuel: US scientists find mercury-free way to source lithium-6 from batteries

SMRTR summary

Scientists have developed a new method to extract lithium-6, essential for nuclear fusion fuel, using zeta-vanadium oxide instead of mercury. This technique can selectively capture lithium-6 from wastewater or batteries, potentially addressing the declining U.S. lithium-6 stockpile. The method achieves 30% enrichment after 25 cycles and could reach 90% within 40 cycles, potentially advancing nuclear fusion as a clean energy solution.
