Abstract:
A multi-phase hydrogen storage alloy comprising a hexagonal Ce 2 Ni 7  phase and a hexagonal Pr 5 Co 19  phase, where the Ce 2 Ni 7  phase abundance is ≥30 wt % and the Pr 5 Co 19  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 Ce 2 Ni 7  phase and a hexagonal Pr 5 Co 19  phase, where the Ce 2 Ni 7  phase abundance is from about 30 to about 72 wt % and the Pr 5 Co 19  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.
