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 K2FeO4 electrode,the electrochemical performance of K2FeO4 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 H2O may participate in the discharge process.It is a electrochemical dominated process in concentrated KOH solutions and a diffused process in diluted solutions.
