Abstract

See full text

A method is provided for fabricating a cyanometallate cathode battery. The method provides a cathode of AXM1YM2Z(CN)N.MH2O, where “A” is selected from a first group of metals, and where M1 and M2 are transition metals. The method provides an anode and a metal ion-permeable membrane separating the anode from the cathode. A third electrode is also provided including “B” metal ions selected from the first group of metals. Typically, the first group of metals includes alkali and alkaline metals. The method intercalates “B” metal ions from the third electrode to the anode, the cathode, or both the anode and cathode to form a completely fabricated battery. In one aspect, a solid electrolyte interface (SEI) layer including the “B” metal ions overlies a surface of the anode, the cathode, or both the anode and cathode. A cyanometallate cathode battery is also provided.
