| Abstract: Two ferrates, K2FeO4 and BaFeO4, had been prepared and characterized by XRD, IR and SEM. The electrochemical tests of the samples were carried out in the voltage range of 0.8～2.0 V and current density of 0.5～3.0 mA·cm-2. The results indicated that performance of Zn-BaFeO4 battery was superior to that of Zn-MnO2 and Zn-K2FeO4 batteries. Nanometer SrTiO3 prepared by Sol-gel methode with different ratio was added to the BaFeO4 cathode in order to improve the discharge performance. The discharge capacity of the BaFeO4 cathode was increased from 224 mAh·g-1 to 246 mAh·g-1 by addition of 5% nanometer SrTiO3. The reason of enhancing BaFeO4 electrochemical performance was discussed. |
