Recently, Electrochemical storage devices based on anion storage mechanisms have emerged. Electrochemical storage devices using zinc bromine batteries or organic anion storage are being studied, and they are utilizing the advantages of having a high voltage range. This research proved the mechanism of adsorbing OH- using LaMnO3, a perovskite oxide material that can be used in aqueous supercapacitors, and manufactured supercapacitors using this. The supercapacitor using LaMnO3 has a voltage range of 1.6V, which is higher than that of a general aqueous capacitor, and such a voltage can overcome limitations in the aqueous system. Analysis of material synthesis was conducted using various methods such as electrochemical analysis, morphology analysis, and lattice structure analysis, and performance analysis was conducted using electrochemical measurement. Through this study, it will be possible to contribute to improving the voltage range and performance of the supercapacitor. |
