  • CATHODE ACTIVE MATERIAL FOR SODIUM SECONDARY BATTERY, METHOD FOR PREPARING THE SAME AND SODIUM SECONDARY BATTERY EMPLOYING THE SAME
    Publication number: 20150243990
    Abstract: A cathode active material for a sodium secondary battery is provided. The cathode active material includes a FeF2.5(0.5H2O)-conductive carbon material composite and is prepared by low-temperature non-aqueous precipitation. The FeF2.5(0.5H2O)-conductive carbon material composite has high capacity and excellent cycle characteristics. In addition, the FeF2.5(0.5H2O)-conductive carbon material composite is prepared in an easy and economical manner by low-temperature non-aqueous precipitation. Therefore, the use of the FeF2.5(0.5H2O)-conductive carbon material composite ensures improved performance of the cathode active material. Further provided are a method for preparing the cathode active material and a sodium secondary battery employing the cathode active material.
