| 摘 要： | 采用三电极体系法,研究K2FeO4电极在不同浓度KOH溶液中的放电行为、电化学阻抗谱(EIS)和极化曲线,以探明K2FeO4在不同浓度碱液中的电极反应特征.结果表明,电解质溶液中的OH-和H2O参与了电极反应过程,在浓度高的KOH溶液中,K2FeO4的电极过程表现为电化学控制步骤;而在稀KOH溶液中,表现为扩散控制特征.

| Abstract: | In order to understand the reaction characteristic of K_2FeO_4 electrode,the electrochemical performance of K_2FeO_4 electrodes in different concentration of KOH solutions were investigated using constant current discharge,EIS(electrochemical impedance spectra) technique and polarization curves in this study.The results show that OH~-and H_2O may participate in the discharge process.It is a electrochemical dominated process in concentrated KOH solutions and a diffused process in diluted solutions. |
