LiVNiO4
LiVNiO4 is a semiconducting, complex layered oxide containing lithium, nickel, and vanadium that is being studied for potential use in battery technologies.
About LiVNiO4
LiVNiO4 is a complex layered lithium transition-metal oxide characterized by its semiconducting electronic nature. As a multi-metal system, it represents an intriguing candidate for structural investigation within the broader family of lithium-based cathode materials.
Its position near the thermodynamic hull suggests that it is a viable target for experimental synthesis. The material is of significant interest to researchers aiming to tune the electrochemical properties of layered oxides by incorporating multiple transition metals into the crystal lattice.
Key Properties
Cross-validated computational properties for LiVNiO4, 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.
Within the class of layered lithium transition-metal oxides, LiVNiO4 serves as a unique alternative to well-established benchmarks like LiCoO2 and LiNiO2. While those materials are widely utilized for their specific redox behaviors, the inclusion of vanadium alongside nickel offers a distinct electronic landscape that differentiates it from the more traditional binary transition-metal compositions found in this group.
