· JVASP-11576· Ca2Ni3O8

Ca₂Ni₃O₈ is a mixed-valence calcium-nickel oxide ceramic compound belonging to the family of layered perovskite-related oxides. This material is primarily of research interest for energy storage and electrochemical applications, where nickel-based oxides are investigated as potential cathode materials, oxygen evolution catalysts, or ionic conductors. While not yet widely deployed in commercial products, this compound represents the broader class of complex metal oxides being developed to overcome performance limitations of conventional battery and fuel cell materials.
