Abstract:
Electrochemical studies were performed on LaNi<FONT SIZE=2><SUB>5-x</sub></font>Ge<FONT SIZE=2><SUB>x</sub></font> 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.
