Microstructure and electrochemical properties of ball-milled AB5+x%VFe alloys

  • 摘要: 采用机械球磨方法制备了MlNi3.55Co0.75Mn0.4Al0.3+x%VFe(质量分数,x=5,10,15,20)储氢合金,研究了合金晶体结构和电化学性能。微结构分析表明,主相AB5晶胞参数a及体积V随球磨时间增加而增加。电化学研究表明,合金的最大容量Cmax及氢扩散系数Dx增加先增加后减少, x=10时达到最大值,分别为310 mAh/g和 7.6×10−11 cm2/s。对合金进行了循环稳定性测试,结果表明,MlNi3.55Co0.75Mn0.4Al0.3+10%VFe球磨10 h的合金在100次循环后放电容量保持率为98%。
