Electrochemical cell.

摘要

A cell comprises an anode, a cathode, and an electrolyte in contact with both the anode and the cathode. The cathode contains, as an electrochemically active material, a polynuclear transition metal cyanide complex having the general formula: MA_K [M (CN)6] l xH2O where M: a metal ion having a valence of A, M: a metal ion having a valence of B, K: a positive number from 1 to 4 l : positive number from 1 to 3, x: a positive number including O, with the proviso that A, B, K, and l satisfy the following equation: A x K = (6 - B) x l
