Abstract
For the purpose of developing the non-stoichiometric Zr-based Laves phase alloy with higher capacity and better performance for electrochemical application, extensive work has been carried out in KAIST. After careful alloy design of hydrogen storage alloys through varing their stoichiometry while susbstituting or adding some alloying elements, the with high capacity and better performance was developed. Consequently the alloy has a high discharge capacity of 394mAh/g and shows a high rate capability equaling to that of commercialized type alloys. On the other hand, in order to develop the hydrogen storage alloy with higher discharge capacity, the hypo-stoichiometric alloys substituted by Ti are under developing. As the result of competitive roles of Ti and , the discharge capacity of alloys is about 400mAh/g(410 mAh/g, which shows the highest level of performance in the Zr-based alloy developed. Our sequential endeavor is improving the shortcoming of Zr-based Laves phase alloy for commercialization, i.e., poor activation property and low rate capability, etc. It is therefore believed that the commercialization of Zr-based Laves phase hydrogen storage alloy for Ni-MH rechargeable battery is in near future.
