Quick Details
Specifications
High capacity and long life Hydrogen storage alloy
1. Type
L1B: High capacity and long life
2. Appearance
Silver gray metal powder, without color change of oxidization and impurities
3. Micro-Crystal Structure
CaCu5 type crystal structure with little second-phase
4. Physical property
The hydrogen storage alloys have various specifications of particle sizes, such as -120 mesh, -150 mesh, -200 mesh and -230 mesh, which could be adjusted according to the demand of customers. -120 mesh and -150 mesh are suitable for dry-producing technology of the electrode of battery, while -200 mesh and -230 mesh are suitable for wet-producing technology.
