About Li2Ni3TeO8
Li2Ni3TeO8 is a thermodynamically stable member of the layered lithium transition-metal oxide family. Characterized by its semiconducting electronic nature, this compound represents a complex structural arrangement that has garnered significant interest across multiple materials databases for its potential in electrochemical applications. Its stability on the convex hull makes it a noteworthy candidate for structural studies within the broader class of lithium-based oxides. By incorporating tellurium into the transition-metal framework, this material offers unique coordination environments that differ from traditional binary or ternary lithium oxides. Its investigation contributes to the fundamental understanding of how heavy-element doping influences the electronic and structural properties of lithium-ion battery materials.
Key Properties
Cross-validated computational properties for Li2Ni3TeO8, 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.
