Li2Co2SnO6
Li2Co2SnO6 is a semiconducting complex oxide composed of lithium, cobalt, and tin that is studied within the context of layered materials for energy storage.
About Li2Co2SnO6
Li2Co2SnO6 belongs to the class of layered lithium transition-metal oxides, characterized by a semiconducting electronic structure. This complex oxide integrates lithium, cobalt, and tin within an oxygen framework, placing it among materials investigated for potential electrochemical applications. While it exhibits structural diversity with multiple reported configurations, its thermodynamic position above the hull suggests it may be metastable under standard conditions. This makes it a subject of interest for researchers studying phase stability and synthesis pathways in lithium-based battery materials.
Key Properties
Cross-validated computational properties for Li2Co2SnO6, 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.
Unlike the highly stable and commercially ubiquitous LiCoO2, which serves as the benchmark for layered cathode materials, Li2Co2SnO6 is a more complex, multi-metal system that faces greater challenges regarding thermodynamic stability. While siblings like LiNiO2 are widely utilized for their high capacity, this tin-containing variant represents a more exploratory approach to modifying the transition-metal layer to potentially tune electrochemical performance.
