Studies On Modified Stability And Battery Performance Of Barium Ferrate (â…¥)

In this paper, the applications and performances of batteries were mentioned. The development of the super-iron battery made from ferrate salts was summarized in details. The chemical synthesis, stability and discharge performance of barium ferrate were exhibited. The modification of BaFeO4 for stabilized purpose was studied. Additives were doped while synthesizing barium ferrate. Effects of additives on the stability and discharge of barium ferrate were investigated systematically.K2FeO4, a precursor of BaFeO4, was synthesized by KClO and Fe(NO3)3. Then BaFeO4 was produced and modified with Ba(OH)2 and additives. The purity of BaFeO4 was titrated by chromite method. The structural characterization was determined by XRD and FTIR method. By the measurements, the purity of BaFeO4 is over 95%, and the crystalline is single and even.The structure of BaFeO4 and BaFeO4-Na2MoO4 composite was determined by XRD, FTIR And the heat properties were displayed by TG/DTA. The stability of the modified BaFeO4 was studied in various conditions. The results show that Na2MoO4 greatly enhances the stability of the solid BaFeO4. During more than 6 months, the purity of modified BaFeO4 with Na2MoO4 was decreased from 92.83% to 63.82% in comparison with the one of BaFeO4 decreasing from 95.35% to 27.05%.The effects of additives on the stability and discharge of the super-iron battery with modified BaFeO4 as active cathodic materials were demonstrated. The results show that the super-iron battery with Na₂MoO₄-modified BaFeO4 has good discharge performances. In the other hand, the stability has been much better enhanced than the unmodified-BaFeO4 battery.Based on the above results, the conclusion can be drew that using Na2MoO4 as additive during synthesizing BaFeO4 can greatly enhance the stability of both the solid BaFeO4 and the super-iron battery.
