| Abstract: | Six kinds of Zr-based hydride alloy were designed. XRD analyses show that the main phase of Zr1-xTix-(NiCoMnV)2.1 alloy is Laves C15 when x is between 0 and 0.5,but the more the content of Ti, the more the Laves C14 phases. The amount of Laves C14 can be up to the amount of Laves C15 after substituted V and Fe by V-Fe alloy in Zr0.6-Ti0.4(NiCoMnVFeCr)1.7 alloy. The electrochemical measurements show that the discharge capacity of Zr0.9Ti0.1-(NiCoMnV)2.1 electrode is about 340mA * h/g at 60mA/g, but with increasing the amount of Ti, the discharge capacity of alloy electrode abruptly decreases; at 300mA/g current density, its Kr can be up to 91%. The discharge capacity of Zr0.6-Ti0.4-(NiCoMn(V-Fe)Cr)1.62 alloy electrode is about 200mA * h/g at first cycle, the maximum capacity is more than that of the electrode with pure V, and about 315mA * h/g. |
