dc.description.abstract Electrochemical studies were performed on LaNi<sub>5-x</sub>Sn<sub>x</sub> with 0(less than or equal to)x(less than or equal to)0.5. We measured the effect of the Sn substituent on the kinetics of charge transfer and diffusion during hydrogen absorption and desorption, and the cyclic lifetimes of LaNi<sub>5-x</sub>Sn<sub>x</sub> electrodes in 250 mAh laboratory test cells. We report beneficial effects of making small substitutions of Sn for Ni in LaNi<sub>5</sub> on the performance of metal hydride alloy anode in terms of cyclic lifetime, capacity and kinetics. The optimal concentration of Sn in LaNi<sub>5-x</sub>Sn<sub>x</sub> alloys for negative electrodes in alkaline rechargable secondary cells was found to lie in the range 0.25(less than or equal to)x(less than or equal to)0.3. en_US
