Characterization of partially Ni substituted manganese hexacyanoferrate cathode material

Manganese Hexacyanoferrate (MnHCF) and partially nickel substituted MnHCF were synthesized by simple coprecipitation method. The water content and chemical formula were obtained by TGA and MP-AES measurements, functional groups by FT-IR analysis, the crystal structure by PXRD and a local geometry by XAS-EXAFS spectroscopy. With the addition of nickel, vacancies and water content increased inside the sample. Crystal structure has changed from monoclinic to cubic. Ni disturbed the local structure of Mn, site, however, almost no change was observed in Fe site.

Automated summary

Manganese Hexacyanoferrate (MnHCF) and MnHCF partially substituted with nickel were synthesized using a simple coprecipitation method. The physical and chemical properties were studied using various analysis techniques. The addition of nickel resulted in increased vacancies and water content inside the sample, as well as a change in the crystal structure.
