Title: Sodium iron(II)-hexacyanoferrate(II) battery electrode and synthesis method

Abstract

A method is provided for synthesizing sodium iron(II)-hexacyanoferrate(II). A Fe(CN)6 material is mixed with the first solution and either an anti-oxidant or a reducing agent. The Fe(CN)6 material may be either ferrocyanide ([Fe(CN)6]4−) or ferricyanide ([Fe(CN)6]3−). As a result, sodium iron(II)-hexacyanoferrate(II) (Na1+XFe[Fe(CN)6]Z.MH2O is formed, where X is less than or equal to 1, and where M is in a range between 0 and 7. In one aspect, the first solution including includes A ions, such as alkali metal ions, alkaline earth metal ions, or combinations thereof, resulting in the formation of Na1+XAYFe[Fe(CN)6]Z.MH2O, where Y is less than or equal to 1. Also provided are a Na1+XFe[Fe(CN)6]Z.MH2O battery and Na1+XFe[Fe(CN)6]Z.MH2O battery electrode.
