Abstract

Li-air battery has attracted extensive attention due to its ultra-high energy density,but its research is in the pri-mary stage.One of the main aspects of current research is to find a suitable cathode catalyst for Li-air battery.The CoFe2O4@Ketjenblack(CFO@KB) materials as cathode catalyst for Li-air battery were successfully synthesized by sol-gel combined with in-situ hydrothermal synthesis method.By adjusting the mass ratio of CoFe2O4 to Ketjenblack(1∶1,3∶1,5∶1 and 7∶1),CFO@KBcomposites with different properties were obtained.Structure of the composites was characterized by XRD.It was found that the synthesized CoFe2O4 in the study was spinel type,and CFO@KB composites still presented its characteristic peak.When the capacity was limited to 180 mA·h/g(based on electrode materials) and the mass ratio of CoFe2O4 to Ketjenblack was1∶1,the composites exhibited the best capacity limiting cycle stability and high cut-off voltage.The voltage difference between charging voltage and discharging voltage was 0.2 V,which was less than the reported value in the existing literature.
