Ultra low-cost hydrogen storage alloy:used as the key material ofthe high capacity and no pollution .

 

 Ultralow-cost  hydrogen storagealloy  

 

   

1. TypeL6A: Ultra low-cost2. AppearanceSilver gray metal powder, without color change of oxidizationand impurities3. Micro-CrystalStructureCaCu5 type crystal structure with littlesecond-phase4. PhysicalpropertyThe hydrogen storage alloys have various specifications ofparticle sizes, such as -120 mesh, -150 mesh, -200 mesh and -230mesh, which could be adjusted according to the demand of customers.-120 mesh and -150 mesh are suitable for dry-producing technologyof the electrode of battery, while -200 mesh and -230 mesh aresuitable for wet-producing technology.

Spec.	Mass Percent (wt.%)
	-120 mesh	-150 mesh	-200 mesh	-230 mesh	-400 mesh
-1	≥ 97				≤ 25
-2		≥ 97			≤ 35
-5			≥ 96		≤ 65
-6				≥ 95

The bulk density varies as the particle size changes and couldbe adjusted properly according to the demand of customers.
