二维硫化铋复合泡沫镍正极材料的制备及在Li-O2电池中的应用
Preparation and electrochemical properties of two-dimensional bismuth sulfide/nickel foam composite material
摘要
Abstract
The two-dimensional bismuth sulfide/nickel foam composite electrodematerial was prepared by hydrothermal method, which avoided the occurrence of the discharge side reaction product when the binder and the carbon substrate were used in the electrode. The morphology and phase of the composites were characterized by using scanning electron microscope (SEM) and X-ray diffractionmeter (XRD). The electrochemical performances of air electrode were studied by cyclic voltammetry and constant current charging/discharging method. The results show that the battery using two-dimensional bismuth sulfide/nickel foam composite material as the air electrode (2D-Bi2S3/Ni air electrode) can reduce the overpotential in the process of charging/discharging, and the charging voltage is below 3.82V in 100 cycles.关键词
