- Physical Vapor Deposition of Hydrogen Storage Alloys and Their Charecterestics as Metal Hydrides Electrodes
- Published at:Taibah Journal of Science
A new method of preparing thin film metal-hydride electrodes for metal-hydride batteries is described. The method consists of simultaneous deposition of multi-component metallic species onto a substrate while bombarding the growing, deposited thin film electrode with a low energy hydrogen ion beam. An amorphous LaNi4 hydride thin film electrode has been prepared by this Hydrogen Ion Beam Assisted Deposition (HIBAD) technique. The electrochemical discharge capacity and cycle life of this electrode in a 6 M KOH solution surpass previously reported values for La-Ni thin film electrodes prepared by other deposition methods.
