摘要:

 通过电沉积及后续热氧化法制备了多级柏叶状Cu2O/Cu锂离子电池负极材料。利用X射线衍射、扫描电子显微镜和能谱仪对制备的样品进行表征,并研究了其电化学性能。结果表明:铜箔表面被均匀覆盖了一层疏松的多级柏叶状Cu2O,粒径约为50~200 nm;多级柏叶状Cu2O/Cu负极经过100次充/放电循环后,该负极的可逆放电比容量仍高达297.2 mA·h/g。

 

 Hierarchical cypress-like Cu2O/Cu anode for lithium ion battery was synthesized via facile electro-deposition and subsequent thermal oxidation in air at 200 ℃. The as-prepared samples were characterized by X-ray diffractometer, scanning electron microscope and energy dispersive spectrometer, respectively, and the corresponding electrochemical performances were further investigated. The results show that Cu foil is uniformly coated by one layer of porous cypress-like Cu2O with the particle size of 50 ~200 nm, and the reversible discharge capacity of the hierarchical cypress-like Cu2O/Cu anode is 297.2 mA·h/g after 100 cycles.
