Hydrogen storage alloys have found applications in the large secondary nickel-metal-hydride cells that serve as powerful energy sources in hybrid vehicles and in the small nickel-metal-hydride cells in such portable electronic devices as digital cameras.
Unique alloys that permit the storage of hydrogen and its discharge, hydrogen storage alloys are employed in the negative electrodes of secondary nickel-metal-hydride cells.
CDK is the top producer of hydrogen storage alloys and in particular the largest supplier of hydrogen storage alloys for the large secondary cells in hybrid vehicles.
