A multi-phase hydrogen storage alloy comprising a hexagonal Ce2Ni7 phase and a hexagonal Pr5Co19 phase, where the Ce2Ni7 phase abundance is > 30 wt% and the Pr5Co19 phase abundance is > 8 wt% and where the alloy comprises a mischmetal where Nd in the mischmetal is < 50 at% or a multi-phase hydrogen storage alloy comprising one or more rare earth elements, a hexagonal Ce2Ni7 phase and a hexagonal Pr5Co19 phase, where the Ce2Ni7 phase abundance is from about 30 to about 72 wt% and the Pr5Co19 phase abundance is > 8 wt% have improved electrochemical performance. The alloys are useful in an electrode in a metal hydride battery, a fuel cell or a metal hydride air battery.
