Abstract
In the Hydrogen Energy System, hydrogen storage alloy is considered to be an important energy carrier. LiOH pretreatment enhances activation process and also H2 absorption even after oxidation. This reaction mechanism is not clearly explained until now. In this study, the surface of LaNi5 alloy treated by LiOD solution was analyzed by TOF-SIMS. Lager intensity of H was confirmed at the place with higher concentration of Li. Higher raction rate can be explained by this higher H concentration caused by LiOH pretreatment.
