· NaNiO2

NaNiO₂ is a sodium nickel oxide ceramic compound belonging to the layered oxide family, characterized by a combination of ionic (Na-O) and transition metal (Ni-O) bonding. This material is primarily of research interest for energy storage and electrochemical applications, particularly in sodium-ion battery cathodes where it offers potential advantages in cost and abundance compared to lithium-based systems. Its layered crystal structure and mixed-valence nickel chemistry make it notable for ion intercalation behavior, though practical engineering deployment remains limited relative to more mature cathode materials.
