Electrochemical hydrogen storage properties of Ti1.4V0.6Ni quasicrystal and TiH composite materials
چکیده انگلیسی
In this study, we use arc-melting and subsequent melt-spinning techniques to prepare Ti1.4V0.6Ni alloy ribbons. The Ti1.4V0.6Ni + xTiH (x = 5, 10, 15 and 20 wt.%) mixture powders are obtained by mechanical ball-milling. Also, we investigate the structure and electrochemical hydrogen storage properties of composite materials. Besides I-phase, FCC and BCC phase, the XRD of composite materials indicates it contains TiH phase. After adding TiH, the discharge capacities of Ti1.4V0.6Ni alloy electrode increase first and then decrease with increasing amount of Ti. The achieved maximum discharge capacity is about 339.8 mA h/g (x = 15 wt.%) at the first discharge cycle. Additionally, composite materials lead to significant improvement in the high-rate dischargeability (HRD) as well as the cyclic stability.
