· Ni6 O8

Ni₆O₈ is a mixed-valence nickel oxide ceramic compound belonging to the family of transition metal oxides, characterized by both Ni²⁺ and Ni³⁺ oxidation states in its crystal structure. This material is primarily investigated in research contexts for electrochemical energy storage and catalysis applications, where its layered oxide structure and variable oxidation states enable enhanced charge transfer and ion mobility compared to simple binary oxides. It is of particular interest in battery cathode materials, supercapacitors, and oxygen evolution catalysts for water splitting, where the mixed-valence chemistry provides improved electrochemical activity and cycling stability.
