采用化学沉积法在泡沫铜表面制备了三维多孔Sn薄膜电极，并利用扫描电镜（SEM）、X射线衍射（XRD）、电化学循环测试和循环伏安（CV）等方法对其形貌和电化学性能进行了研究。锡薄膜作为锂离子电池负极时，多孔骨架和微孔在抑制剧烈的体积变化方面表现出很大的结构优势。初始容量为676 mAhg-1的样品C的膜电极显示出良好的循环性能，在100次循环后保持313 mAhg-1的容量。
Three-dimensional porous Sn thin film electrodes were prepared by electroless deposition on copper foam, then its morphology and electrochemical property were studied by means of scanning electron microscope (SEM), X-ray diffraction (XRD), electrochemical cycling test and cyclic voltammetry (CV). The porous framework and micro-holes have shown a great structure advantage in restricting severe volume changes when the Sn thin film was employed as anode for lithium-ion battery. The film electrode of sample C with an initial capacity of 676mAhg−1showed good cycle performance displayed by retaining a capacity of 313mAhg−1after 100 cycles.
