About Sr4LiMn2Ga2O11
Sr4LiMn2Ga2O11 is a complex layered lithium transition-metal oxide characterized by its semiconducting electronic nature. As a multi-element oxide incorporating strontium, gallium, and manganese, it represents a specialized structural arrangement within the broader family of lithium-based functional materials.
While this compound exhibits a variety of reported structural configurations, it is categorized as being above the thermodynamic hull, suggesting it may be metastable under standard conditions. Its unique composition makes it a subject of interest for researchers investigating the interplay between transition metals and alkaline earth elements in layered oxide frameworks.
Key Properties
Cross-validated computational properties for Sr4LiMn2Ga2O11, aggregated across 2 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 cathode materials such as LiCoO2 and LiMn2O4, Sr4LiMn2Ga2O11 occupies a more niche position in the layered lithium transition-metal oxide class. While siblings like LiNiO2 are optimized for high-capacity energy storage, this strontium-rich variant serves primarily as a complex structural study rather than a standard electrochemical component.
