A secondary 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 an oxidation product of a polynuclear metal cyanide complex of the general formula: M<A>[M<B>(CN)6]I.xH2O where M<A>: a metal ion having a valence of A, M<B>: a metal ion having a valence of B, K: a positive number of from 1 to 4, I: a positive number of from 1 to 3, x: a positive number inclusive of 0, and wherein A, B, K and I satisfy the following relation: A x K = (6 - B) x I. The anode contains as an electrochemically active material a reduction product of the polynuclear metal cyanide complex. Thus, in one Example, the cathode may contain Berlin Green and the anode may contain Everitt's salt. |
