Co3O4添加剂对锂硫电池电化学性能的影响
Effects of Co3O4 as an additive on electrochemical properties of lithium/sulfur battery
摘要
Abstract
Cobaltosic oxide and electrically conductive carbon black KS-6 were uniformly mixed by the solution-dipping method,with the Co3O4-KS-6/S composite cathode material formed.X-ray diffraction(XRD),scanning electron microscope (SEM),energy dispersive spectrometer (EDS),thermogravimetry analysis (TG),cyclic voltammetry (CV) and constant current charge and discharge testing were used as materials analysis to investigate the effect of Co3O4 on electrochemical properties of lithium/sulfur battery.The results showed that the Co3O4,S were distributed uniformly in the KS-6 of Co3O4-KS-6/S composites.The initial discharge capacity is 1298 mA · h/g at 0.1C rate,and after 100 cycles,the capacity retention rate is 30.3 ％.It is much higher than those of KS-6/S composites,which displayed the initial discharge capacity for 999 mA · h/g at 0.1C rate,and after 100 cycles,the capacity retention rate is 25.8 ％.关键词
