Performance of Co-Pt binary catalyst for lithium-air battery
摘要
Abstract
The CoO and Pt catalyst (Co-Pt catalyst) as binary catalyst was applied to the lithium-air battery.The physical performances of the Co-Pt catalyst were characterized by field emission scanning electron microscopy (FESEM) and X-ray powder diffraction (XRD),and the electrochemical performances were studied by cyclic voltammetry,AC impedance and constant current charging/discharging.The results show that the Co-Pt binary catalyst has excellent electrochemical performance.The initial discharge specific capacity and the energy density can achieve 2225.8 mAh · g-1 and 5822.8 mWh · g-1 at the current density of0.025× 10-3A · cm-2.关键词
