| 摘 要： | 采用机械合金化方法用Ni粉和Ti粉得到了Ti3Ni2非晶合金。晶态Ti3Ni2合金初始容量比非晶合金要高。晶态合金初始容量可以达到240mAh／g。而非晶合金容量为173mAh／g。随着循环次数的增加，晶态合金放电容量呈线性下降趋势。而对于非晶电极材料来说，随着循环的进行，初始容量下降，但是达到一定循环次数以后，电极的放电容量达到基本稳定。

| Abstract: | Amorphous Ti3Ni2 alloy was prepared by mechanical alloying with Ni and Ti powder. The starting discharge capacity of crystallized Ti3Ni2 alloy is higher than amorphous alloy, 240mAh/g for crystallized alloy,174mAh/g for amorphous alloy. With the increase of cycle number, the discharge capacity of crystallize alloy decrease linearly. For amorphous alloy, discharge capacity decrease with charge/discharge process. But when the cycle number get certain value, the discharge capacity become constant. |
