Abstract
A detailed electrochemical evaluation of Sn-modified LaNi5 was perform ed to evaluate its performance as a negative electrode in alkaline rec hargeable cells. Substituting small amounts of Sn for Ni provides a la rge improvement in the initial capacity and cycle lifetime of the elec trode, and also serves to improve the kinetics of hydrogen absorption- desorption processes.
