采用一种新颖、简便的电化学方法制备了高度有序的纳米多孔Sn-Ni合金薄膜。所制备的纳米多孔Sn-Ni合金膜电极在300 mA g-1的电流密度下100次循环后显示出537 mAh g-1的可逆容量，并且在高达2000 mA g-1的电流密度下仍然提供230 mAh g-1的容量。纳米多孔Sn-Ni合金膜电极具有优异的储锂性能，有望成为锂离子电池的高性能负极材料。
A highly ordered nanoporous Sn-Ni alloy film has been prepared by a novel and facile electrochemical procedure. The as-prepared nanoporous Sn-Ni alloy film electrode shows a reversible capacity of 537 mAh g−1after 100 cycles at a current density of 300 mA g−1, and it still delivers a capacity of 230 mAh g−1at a current density as high as 2000 mA g−1. The nanoporous Sn-Ni alloy film electrode with the excellent lithium storage performance reveals the promising potential as a high-performance anode for lithium-ion batteries.
