Rechargeable hydrogen storage in nanostructured mixtures of hydrogenated carbon and lithium hydride
ApplPhysLett_86_241914.pdf 66.5 KB
A hydrogen storage ability caused by the interaction between nanostructured carbon sCnanoHxd and lithium hydride sLiHd is demonstrated, which should be recognized as Li-C-H system in the H-storage materials. Especially, the 2:1 mixture of CnanoHx and LiH exhibited promising hydrogen storage properties with a rechargeable hydrogen capacity of more than 4 mass% below 350 °C, preserving the nanostructural feature in the mixture even after hydrogen release. On the other hand, the 1:2 and 1:1 mixtures exhibited the crystal growth of Li2C2 after hydrogen desorption, leading to poorer hydrogen rechargeability.
