Li2Ni2SbO6
Li2Ni2SbO6 is a metastable, semiconducting layered lithium transition-metal oxide studied for its potential role in advanced electrochemical energy storage.
About Li2Ni2SbO6
Li2Ni2SbO6 belongs to the class of layered lithium transition-metal oxides, characterized by its distinct structural arrangement and semiconducting electronic nature. As a metastable phase, it represents a specialized configuration within the broader family of lithium-based oxides often investigated for electrochemical potential. Its unique composition of lithium, nickel, antimony, and oxygen provides a complex framework that researchers study to understand ion transport and structural stability in energy storage systems. While not as widely commercialized as some of its counterparts, it remains a significant subject of structural analysis across multiple materials databases.
Key Properties
Cross-validated computational properties for Li2Ni2SbO6, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
