· JVASP-56646· Na2FeNiF7

Na2FeNiF7 is a mixed-metal fluoride compound containing sodium, iron, and nickel in a fluoride matrix. This is an experimental/research material rather than an established industrial alloy, studied primarily for electrochemical energy storage applications where metal fluorides offer potential advantages in ionic conductivity and electrochemical stability. The compound belongs to a family of fluoride materials being investigated as solid-state electrolytes or cathode materials for advanced battery systems, where the combination of multiple transition metals (Fe, Ni) and fluoride chemistry can tune electrochemical performance and ionic transport properties.
