摘　　要：本文将一组金属有机电解质应用于双相氧化还原液流电池。该电解质由铁和联吡啶衍生物配体组成络合物,带有+2或+3价离子电荷,只溶于乙腈和3-戊酮等有机溶剂,但极不溶于水。特别是铁(II)-4,4’-二叔丁基-2,2’-联吡啶络合物的3-戊酮溶液在1.2V vs. SHE的电位下循环时表现出优异的电化学可逆性、动力学和稳定性。这是首次报道这些电解质有机溶液在氧化还原液流电池中的应用。In this paper,a group of metal organic electrolytes were used in two-phase redox Flow battery.The electrolyte consists of a complex of iron and a bipyridine derivative ligand,with+2 or+3 valence ion charges,and is only soluble in organic solvents such as acetonitrile and 3-Pentanone,but extremely insoluble in water.In particular,the 3-Pentanone solution of iron(II)-4,4'-di-tert-butyl-2,2'-bipyridine complex showed excellent electrochemical reversibility,kinetics and stability when circulating at a potential of 1.2V vs.SHE.This is the first report on the application of these electrolyte organic solutions in redox Flow battery.
