Improved electrochemical performance of Ti1.4V0.6Ni hydrogen storage alloy in its composite with LiAlH4
چکیده انگلیسی
Ti1.4V0.6Ni + xLiAlH4 (x = 0.5, 1, 1.5, 2, 2.5, wt.%) composites were prepared by ball-milling, and the effects of LiAlH4 content on structure and electrochemical properties of the composites were investigated systematically. The addition of LiAlH4 to the Ti1.4V0.6Ni alloy significantly affected the morphology and size of the composite particles. The electrochemical cycling stability and rate dischargeability of the composite electrodes benefitted from adding some LiAlH4 (x = 1), which however deteriorated when the LiAlH4 content increased further. The positive effect of LiAlH4 on the electrochemical performance of the studied alloy was caused by suppression of the dissolution of active components of the Ti1.4V0.6Ni hydrogen storage alloy.
