Embodiment 1
[0033] Design a hydrogen storage alloy whose chemical formula is Ti 1.02 Cr 1.2 Fe 0.6 mn 0.2 B 0.01 , Calculate the addition amount of each raw material according to the chemical formula. The raw material purity of Ti, Cr, Fe, Mn and B all reach above 99%. The above-mentioned raw materials are weighed according to the calculated addition amount after being cleaned and dried, and an additional 3% weight of Mn is added according to the proportioning amount. Put the weighed sample in the water-cooled copper crucible of the magnetic levitation furnace. After evacuating to a vacuum degree of 1.02 Cr 1.2 Fe 0.6 mn 0.2 B 0.01 match.
[0034] The prepared hydrogen storage alloy ingot was crushed into particles with a particle size of less than 200 microns, and then loaded into a reactor to measure the hydrogen storage performance. The hydrogen storage alloy is first evacuated under the heating condition of 400°C for 30 minutes, and then filled with high-pressure hydrogen ga...
