摘要
Abstract
In this paper,Tin doped iron anode materials for iron nickel secondary batteries were pre-pared by the sol gel method using FeC2O4·2H2O as the iron source,SnO2 as the tin source,citric acid as the carbon source and reducing agent.The influence of different citric acid contents on anode ma-terials was explored,and the effects of two sulfide additives,NiS and FeS,on the performance of the synthesized anode were investigated.XRD,SEM,CV and EIS were used to characterize the struc-ture,morphology,and electrochemical properties of the synthesized materials.The results show that high temperature sintering of citric acid into carbon provides the main carbon source for the nega-tive electrode material,and when the ratio of metal ions to citric acid was 1∶1.5,the iron specific ca-pacity prepared reaches 523 mAh/g.The addition of appropriate proportions of sulfides can enhance the specific capacity of anode materials.Among them,the anode material with 5%FeS added has a discharge specific capacity of 582 mAh/g,the highest discharge specific capacity,and good cycling sta-bility.关键词
