METHOD FOR PRODUCING HYDROGEN STORAGE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a lithium-based (Li-N-H-based) hydrogen storage material exhibiting excellent hydrogen release properties under conditions of≥4% released amount of hydrogen and≤260°C hydrogen release temperature in a hydrogen production method for converting a raw material comprising a mixture of LiNH2and LiH into lithium imide (Li2NH) and hydrogen. SOLUTION: When a mixture raw material obtained by adding a catalyst to the raw material comprising the mixture of LiNH2and LiH is crushed in the hydrogen production method for converting the raw material comprising the mixture of LiNH2and LiH into lithium imide (Li2NH) and hydrogen, the mixture raw material is crushed under a crush condition satisfying G≥1 and 12) is the gravitational acceleration to be imparted to a crushing medium of a crushing apparatus; T (hr) is a crushing time; w (g) is the weight of the mixture raw material to be crushed).
