· JVASP-53367· FeNi2S4

FeNi₂S₄ is an iron-nickel sulfide compound belonging to the thiospinel family of metal sulfides. This material is primarily of research interest rather than established industrial production, investigated for its potential in electrochemical energy storage and catalytic applications where mixed-metal sulfides offer tunable electronic properties and enhanced activity compared to single-metal alternatives. The layered sulfide structure and mixed-valence transition metals make it attractive for battery electrode materials, supercapacitors, and heterogeneous catalysts, though practical engineering applications remain largely in the development phase.
