rGO量对SnO2-Fe2O3/rGO锂离子电池负极材料性能的影响
Influences of rGO content on properties of SnO2-Fe2O3/rGO anode for lithium ion batteries
摘要
Abstract
In order to improve the electrochemical performance of SnO2-Fe2O3,SnO2-Fe2O3/rGO nanocomposites were syn-thesized by one-step hydrothermal method.The effect of the amount of rGO on structure and electrochemical per-formances of SnO2-Fe2O3/rGO was studied by using XRD,SEM,electrochemical workstation and LAND battery test system.The results demonstrated that the incorporation of rGO can improve the cycling stability and rate per-formance of SnO2-Fe2O3.For SnO2-Fe2O3/rGO50 nanocomposite,at a charge-discharge current density of 160 mA/g,after 100 cycles,the discharge specific capacity keeps 596.9 mAh/g and Coulombic efficiency is 98%. Even at current density of 1 A/g,its average discharge specific capacity is still 366.6 mAh/g.关键词
