合成了分子式为M-6-m(n+)[FeM+(CN)(6)](N)(M=V，Mn，Co，Ni，Cu)的金属氰化铁，并对其充放电行为进行了讨论。在V-Fe络合物中，平均放电电位约为3.6V，对应于V3+的还原，而Mn、Co、Ni和Cu络合物的平均放电电位约为3.3V，这是由于晶格中的[Fe3+(CN)6](3-)单元还原所致。V、Mn、Co、Ni络合物的比容量约为60-80 mA h g(-1)，而铜络合物的比容量几乎是其两倍，约为140 mA h g(-1)。这是因为除了[Fe3+(CN)(6)](3-)-->；[Fe2+(CN)(6)](4-)还原之外，还考虑了Cu2+还原为Cu2+所引起的容量。(C)1999 Elsevier Science S.A.保留所有权利。
Iron cyanometallates having a formula, M-6-m(n+)[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. (C) 1999 Elsevier Science S.A. All rights reserved.
