摘要：

Nickel foil-supported porous Fe3O4 films are prepared by chemical bath deposition. The film subjected to 60 min deposition has an areal density of 0.68 mg cm(-2), and is composed of interconnected nanosheets assembled by parallel-aligned nanobelts. As anode materials for lithium ion batteries, its electrochemical performance is studied by galvanostatic discharge-charge and cyclic voltammetry measurements. It delivers an initial charge capacity of 806 mAh g(-1) and an initial coulombic efficiency of 77%. It shows good cycling stability and rate capability. The enhanced electrochemical performance is attributed to the interconnected nanosheet structure. (c) 2016 Elsevier B.V. All rights reserved.
