Technology Marketing Summary

Idaho National Laboratory (INL) created a novel method and device for secure, high-density storage of tritium. The high-density tritium is bonded with carbon by irradiating an intercalated precursor into tritium bonded with carbon in a substrate.  Existing solutions to safely secure tritium result in a low-density tritium, minimizing tritium’s potential as a significant energy source. 

Description

A method and device for producing secure, high-density tritium bonded with carbon.  A precursor is intercalated between carbon in the substrate, then irradiated until at least a portion of the precursor is transmutated into tritium and bonds with the carbon in the substrate.  This forms bonded tritium, tritium bonded with carbon, that produces electrons via beta decay.  The substrate can be highly-ordered pyrolytic graphite, carbon fibers, carbon nanotunes, buckministerfullerenes, or combinations thereof.  The precursor can be boron-10 or lithium-6.  The resulting bonded tritium can be used in a long-term power source (preferably between 10 and 20 years), capable of operating under extreme environments (e.g. deep ocean, vacuum of space, high altitude, etc.) and under extreme temperatures (preferably up to 300°F).

Benefits

Cost effective, improved functionality, more secure

Applications and Industries

Energy sector, betavoltic batterie

Method and device for secure, high-density tritium bonded with carbon
A method and device for producing secure, high-density tritium bonded with carbon. A substrate comprising carbon is provided. A precursor is intercalated between carbon in the substrate. The precursor intercalated in the substrate is irradiated until at least a portion of the precursor, preferably a majority of the precursor, is transmutated into tritium and bonds with carbon of the substrate forming bonded tritium. The resulting bonded tritium, tritium bonded with carbon, produces electrons via beta decay. The substrate is preferably a substrate from the list of substrates consisting of highly-ordered pyrolytic graphite, carbon fibers, carbon nanotunes, buckministerfullerenes, and combinations thereof. The precursor is preferably boron-10, more preferably lithium-6. Preferably, thermal neutrons are used to irradiate the precursor. The resulting bonded tritium is preferably used to generate electricity either directly or indirectly.
