对Sn改性的LaNi[sub 5]进行详细的电化学评价，以评价其作为碱性可充电电池中的负极的性能。用少量的Sn代替Ni提供了电极的初始容量和循环寿命的大的改进，并且还用于改进氢吸收-解吸过程的动力学。
A detailed electrochemical evaluation of Sn-modified LaNi[sub 5] was performed to evaluate its performance as a negative electrode in alkaline rechargeable cells. Substituting small amounts of Sn for Ni provides a large improvement in the initial capacity and cycle lifetime of the electrode, and also serves to improve the kinetics of hydrogen absorption-desorption processes.
