Fe1 Ni3 P4 O16

Fe₁Ni₃P₄O₁₆ is a mixed-metal phosphate compound combining iron, nickel, and phosphorus oxides, belonging to the family of transition-metal phosphates that exhibit semiconducting behavior. This material is primarily of research interest for energy storage and electrochemical applications, where nickel-iron phosphates have shown promise as alternatives to traditional electrode materials due to their potential for enhanced ionic conductivity and catalytic activity. The specific stoichiometry suggests investigation into layered or framework phosphate structures that could be relevant for battery cathodes or electrocatalytic applications, though commercial deployment remains limited compared to more established phosphate compounds.
