摘要：

Three-dimensional porous Sri 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 Sri thin film was employed as anode for lithium-ion battery. The film electrode of sample C with an initial capacity of 676 mAh g(-1) showed good cycle performance displayed by retaining a capacity of 313 mAh g(-1) after 100 cycles. (C) 2009 Elsevier Ltd.
