Corrosion and degradation behavior of Zr-based AB2 alloy electrodes during electrochemical cycling

Zr-based AB2 Laves phase alloys are promising materials for the negative electrodes in Ni–MH batteries. In this work, their cyclic durability and corrosion behavior in the electrolyte were systematically investigated using instrumental analyses such as ICPS, XRD, SEM, EPMA, XPS as well as PCT and specific surface area measurement.
