▎ 摘  要

NOVELTY - High-hydrogen storage composite material comprises lithium borohydride (LiBH4) and reduced graphene oxide (RGO) material, which has a surface with dense pores, where LiBH4 material is uniformly dispersed in the pores. USE - High-hydrogen storage composite material used in fuel cell hydrogen supply source and hydrogen energy source e.g. for car. ADVANTAGE - The composite material has initial hydrogen desorption temperature of less than 100 degrees C and hydrogen absorption amount of 5-18 wt.% at less than 500 degrees C. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of high-hydrogen storage composite material comprising uniformly mixing LiBH4 and RGO; and using melt permeation method to disperse the LiBH4 uniformly into the RGO pores prepared by chemical oxidation reduction method in inert gas protection atmosphere and water-oxygen free condition.
