Six kinds of Zr-based hydride alloy were designed. XRD analyses show that the main phase of Zr 1-xTi x-(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 Zr 0.6- Ti 0.4(NiCoMnVFeCr) 1.7 alloy. The electrochemical measurements show that the discharge capacity of Zr 0.9Ti 0.1- (NiCoMnV) 2.1 electrode is about 340 mA·h/g at 60 mA/g, but with increasing the amount of Ti, the discharge capacity of alloy electrode abruptly decreases; at 300 mA/g current density, its K r can be up to 91%. The discharge capacity of Zr 0.6- Ti 0.4-(NiCoMn(V-Fe)Cr) 1.62 alloy electrode is about 200 mA·h/g at first cycle, the maximum capacity is more than that of the electrode with pure V, and about 315 mA·h/g.

The electrochemical measurements show that the discharge capacity of Zr 0.9 Ti 0.1 - (NiCoMnV) 2.1 electrode is about 340 mA · h / g at 60 mA / g, but with increasing the amount of Ti, the discharge capacity of alloy electrode abruptly decreases; at 300 mA / g current density, The discharge capacity of Zr 0.6-Ti 0.4- (NiCoMn (V-Fe) Cr) 1.62 alloy electrode is about 200 mA · h / g at first cycle, the maximum capacity is more than that of the electrode with pure V, and about 315 mA · h / g.
