146th TMS Annual Meeting and Exhibition / Symposium on Mechanical and Creep Behavior of Advanced Materials - A Structural-Materials-Division Symposium Honoring Prof. K. Linga Murty, California, Amerika Birleşik Devletleri, 26 Şubat - 02 Mart 2017, ss.657-663
A Mg-Ni hydrogen storage alloy was produced as a film by molten salts electrolysis and diffusion process. Mg and Ni was co-deposition on a nickel substrate from 20 wt% MgCl2 + 2 wt% NiCl2 and balans NaCl + KCl mixture. The electrodeposition was conducted at 700-750 degrees C and constant current density of 0.5 A cm(-2) for 60 min. The phase composition and microstructure of Mg-Ni alloy were detected by X-ray diffraction (XRD) and scanning electron microscope (SEM). The electrode performance in 6 M KOH solution were characterized by cyclic charge-discharge experiment. The best initial discharge capacity (375 mAhg(-1)) and acceptable capacity retaining rate (70%) were obtained at the 750 degrees C alloy.
