采用电沉积法制备了不同Sn/Ni比的Sn-Ni合金薄膜，并对其作为锂离子二次电池负极进行了表征。放电容量的初始下降随样品的Sn含量而变化;即，对于具有54原子% Sn和62原子% Sn的样品，下降小于100 mAh/g，而对于具有84原子% Sn和92原子% Sn的样品，下降超过500 mAh/g。在这些薄膜中，62原子%的Sn膜显示出最高的ca. 650 mAh/g，而其它样品（54原子% Sn，84原子% Sn. 92原子%。Sn）显示出300 mAh/g的容量。
Thin Sn-Ni alloy films containing various Sn/Ni ratios were prepared by electrodeposition and characterized as lithium-ion secondary battery anodes. The initial drop in discharge capacity varied with the Sn content of thesample; i.e., for samples with 54 atom % Sn and 62 atom % Sn, the drop was less than 100 mAh/g, whereas for those with 84 atom % Sn and 92 atom % Sn, the drop exceeded 500 mAh/g. Among these thin films, the 62 atom % Sn film showed the highest reversible capacity of ca. 650 mAh/g at about the 70th cycle, whereas the other samples (54 atom % Sn, 84 atom % Sn. 92 atom %. Sn) showed a capacity of 300 mAh/g.
