In this study, La15Fe2Ni72Mn7B2Al2 hydrogen storage was composited with grapheme and the effect of ball milling time on the microstructure and properties of the alloy were studied. XRD analysis shows that the as-milled composites alloy consists of LaNi5, La3Ni13B2 and (Fe, Ni) phases. No new phase is formed in the composites alloy with the milling time increases. The ball-milling treatment produced amorphous structure and refined the particle size of the alloy. Electrochemical studies revealed that the discharge capacity of composites alloy was significantly improved. The ball-milling process enhances the maximum discharge capacity and the dynamics performance, especially for the alloy with milling time of 30 min. Moreover, self-discharge behavior of the composites alloy were also increased by ball-milled. [ABSTRACT FROM AUTHOR] |
