Abstract

Iron cyanometallates having a formula, Mg6-mn+[Fem+ (CN)6]n (M = V, Mn, Co, Ni, Cu) were prepared and their charge-discharge behavior was discussed. In the V-Fe complex, average discharge potential is about 3.6 V corresponding to reduction of V3+ , whereas the Mn, Co, Ni, and Cu complexes show similar discharge potential around 3.3 V that is resulted from reduction of [Fe3+ (CN)6]3- unit in the lattice. The specific capacity of V, Mn, Co, Ni complexes show about 60-80 mA h g-1, but copper complex indicates almost double capacity, ca. 140 mA h g-1. This is explained by considering the capacity caused by Cu2+ to Cu+ reduction in addition to [Fe3+ (CN)6]3+ → [Fe2+ (CN)6]4- reduction.
