针对Ti-Mn基储氢合金循环稳定性差这一问题， 提出了一个关于Ti-Mn基储氢合金循环稳定性的简易模型， 并引入两个表示储氢合金本征 属性的因子： 活化特征因子β和容量衰减因子A。 采用该模型可以描述合金活化与容 量衰减的全过程。 实验测量了Ti0.26Zr0.07V0.21Mn0.1Ni0 .3Cr0.03 和Ti0.26Zr0.07V0.19Mn0.1Ni0.3Cr 0.05合金的活化与充放电循环过程， 理论与实验有较好的吻合关系。
In view of bad cycle stability of Ti-Mn based alloys, a simple model for the cycle life of Ti-Mn hydrogen-storage alloys was give. Two factors were introduced to indicate the intrinsic characteristic of h ydrogen-storage metal: active factor, β, and capacity-degrade factor, A . The model can describe the whole process of activation and degradation. The activation and cycle process of two alloys: Ti0.26Zr0.07V0.21M n0.1Ni0.3Cr0.03 and Ti0.26Zr0.07V0.19Mn 0.1Ni0.3Cr0.05 were measured and the results agreed with the theory well.
