Li2Co3TeO8
Li2Co3TeO8 is a metastable, semimetallic layered lithium transition-metal oxide used in advanced materials research.
About Li2Co3TeO8
Li2Co3TeO8 is a complex layered lithium transition-metal oxide containing cobalt and tellurium. Its unique electronic structure, characterized as near-zero-gap or semimetallic, distinguishes it from typical insulating or semiconducting oxides in this family.
As a metastable phase, this compound represents an intriguing target for materials synthesis and structural analysis. It is primarily investigated within the context of lithium-ion battery research, where the interplay between transition metals and tellurium can influence charge transport and structural stability.
Key Properties
Cross-validated computational properties for Li2Co3TeO8, 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.

How It Compares
Within the layered lithium transition-metal oxides class.
While standard members of the layered lithium transition-metal oxide class like LiCoO2 and LiNiO2 are widely utilized as stable cathode materials, Li2Co3TeO8 occupies a more specialized, metastable niche. Unlike the well-characterized LiMn2O4 or Li2MnO3, this tellurium-containing oxide exhibits semimetallic behavior, offering a distinct electronic profile compared to the more traditional, wider-gap oxides in the group.
