| 简介 |
A method is provided for synthesizing a metal-doped transition metal hexacyanoferrate (TMHCF) battery electrode. The method prepares a first solution of AxFe(CN)6 and Fe(CN)6, where A cations may be alkali or alkaline-earth cations. The method adds the first solution to a second solution containing M-ions and M`-ions. M is a transition metal, and M` is a metal dopant. Subsequent to stirring, the mixture is precipitated to form AxMcM`dFez(CN)n.mH2O particles. The AxMcM`dFez(CN)n.mH2O particles have a framework and interstitial spaces in the framework, where M and M` occupy positions in the framework. Alternatively, the method prepares AaA`bMyFez(CN)n.mH2O particles. A and A` occupy interstitial spaces in the AaA`bMyFez(CN)n.mH2O particle framework. A metal-doped TMHCF electrode is also provided. |
