Nanocrystalline hydrogen storage alloys for rechargeable batteries
AB -type intermetallic compounds were prepared by the melt spinning method. Structure analysis was carried out by X-ray 5 diffractometry, SEM and high resolution electron microscopy. The hydrogen storage capacity was determined by isothermic mass controlled absorption of hydrogen and by electrochemical charge /discharge cycles. A variation of the preparation parameters showed that a nanocrystal...

متن کاملEFFECTS OF TiO2 ADDITIVE ON ELECTROCHEMICAL HYDROGEN STORAGE PROPERTIES OF NANOCRYSTALLINE /AMORPHOUS Mg2Ni INTERMETALLIC ALLOY
Abstract: Mg2Ni alloy and Mg2Ni–x wt% TiO2 (x = 3, 5 and 10 wt %) composites are prepared by mechanical alloying. The produced alloy and composites are characterized as the particles with nanocrystalline/amorphous structure. The effects of TiO2 on hydrogen storage properties are investigated using anodic polarization and electrochemical impedance spectroscopy. It is demonstrated that the initia...
متن کاملPERFORMANCE OF AB, ALLOYS FOR HYDROGEN STORAGE AND HYDRIDE ELECTRODES
Two types of hydride electxodes are potential candidates to replace the Cd elecsode in NilCd batteries, One is of the A type where A is a rare earth metal or mixture thereof, and B is the transition metal. The other is commonly referred to as A type. A , type alloys with partial substitution of the B element in A type hydride material (Ovonic) with Co, Mn, Al, and Fe were studied (A compo...
متن کاملEnhanced Hydrogen Storage Kinetics of Nanocrystalline and Amorphous Mg2Ni-type Alloy by Melt Spinning
Mg₂Ni-type Mg₂Ni1-xCox (x = 0, 0.1, 0.2, 0.3, 0.4) alloys were fabricated by melt spinning technique. The structures of the as-spun alloys were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The hydrogen absorption and desorption kinetics of the alloys were measured by an automatically controlled Sieverts apparatus. The electrochemical hydrogen storage kine...
