Hydrogen storage material

摘要

The disclosure relates to a hydrogen storage material composed of a Ti-Mn-M alloy in which M represents at least one metal selected from the group consisting of vanadium, chromium, iron, cobalt, nickel, copper and molybdenum, and which defines an alloy phase of a Laves phase having a hexagonal crystal structure of MgZn2(C14) type and crystal lattice parameters a=4.86 DIFFERENCE 4.90A and C=7.95 DIFFERENCE 8.02A. The hydrogen storage material is economical and suited to practical purposes, since it readily absorbs a large amount of hydrogen at room temperature and reversibly discharges a large amount of hydrogen with safety through variations of ambient hydrogen pressure, temperature conditions or electro-chemical conditions.
