Electrochemical Properties of LaNi(sub 5-x)Ge(sub x) Alloys in Ni-MH Batteries

Electrochemical studies were performed on LaNi(sub 5-x)Ge(sub x) metal hydride alloys with 0 <= x <= 0.5. We carried out single-electrode studies to understand the effects of the Ge substituent on the hydrogen absorption characteristics, the electrochemical capacity, and the electrochemical kinetics of hydrogen absorption and desorption.
