· Na4 Fe2 Ni2 F14

Na₄Fe₂Ni₂F₁₄ is a mixed-metal fluoride compound combining sodium, iron, and nickel in a fluoride lattice structure, classified as a semiconductor material. This is primarily a research-phase compound studied for its potential in energy storage and electrochemical applications, particularly as a component in novel battery electrolytes or cathode materials where the combination of transition metals (Fe, Ni) and ionic conductivity from sodium fluoride networks shows promise. The material represents an emerging class of multi-cation fluoride frameworks being explored to overcome limitations of conventional lithium-ion and sodium-ion battery systems, though industrial adoption remains limited.
