锂离子电池负极材料纳米Ni3Sn2的溶剂热合成与电化学性能
Solvothermal Synthesis and Electrochemical Performance of Nano-Ni3Sn2 Used as Anodes for Lithium-ion Batteries
摘要
Abstract
A nano-Ni3Sn2 intermetallic compound was prepared by solvothermal method for an anode material of lithium-ion batteries. The samples were characterized by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). The electrochemical performances of the materials were evaluated by galvanostatic charge and discharge cycling in a lithium-ion model cell Li/LiPF6(EC+DMC)/ Ni3Sn2. It was found that the first delithiation capacity of nano-Ni3Sn2 was 136 mAh·g-1. The annealed Ni3Sn2 electrodes exhibited a better capacity retention compared to the unannealed Ni3Sn2 electrodes.关键词
