Title: “Graphene-Wrapped” Complex Hydrides as High-Capacity, Regenerable Hydrogen Storage Materials

Abstract

This project focused on the development of a new class of hydrogen storage material, hydride@graphene, for the next-generation H2 powered fuel cell vehicles. The new approach was based on a recent technology breakthrough through the collaboration between Argonne National Laboratory (ANL) and Shanghai Jiao Tong University (SJTU). A “nanoencapsulated” sodium borohydride-graphene composite, NaBH4@graphene, was successfully synthesized using a simple solvent-based method. The new composite offers regenerable high H2 storage capacity in multiple dehydrogenation and rehydrogenation cycles. Under this short project, we successfully synthesized catalyst-doped NaBH4@graphene composite and demonstrated five dehydrogenation (DH) and rehydrogenation (RH) cycles with measured gravimetric capacity > 7.4 wt% at 406 ºC. We also successfully demonstrated the improvement in hydrogen release kinetics by lowering DH temperature of 320 degree over bulk NaBH4 or 138 degree over NaBH4@G as the benchmark at the beginning of the project. We collaborated with members of the Hydrogen Materials – Advanced Research Consortium (HyMARC) team in computational modeling, structural characterization and performance measurement.
