Abstract
An alkali-treated Zr0.9Ti0.1Ni1.1Co0.1Mn0.6V0.2 alloy was investigated with X-ray photoelectron spectroscopy (XPS) and Auger electron spectr oscopy (AES) in combination with an Ar+ sputter-etching technology. As a result, it was found that alkali-treatment brought about a Ni-rich surface due to the selective dissolution of Ti, Co, Mn, V, etc. Such a Ni-rich surface plays a significant role in facilitating the activati on of the alloy in charge-discharge cycle tests.
