Sr2LiO12
Sr2LiO12 is a complex, metastable lithium-strontium oxide with semimetallic electronic properties.
About Sr2LiO12
Sr2LiO12 is a complex lithium oxide characterized by a semimetallic electronic structure. Its composition, involving strontium, lithium, and oxygen, places it in a unique subset of oxide materials where electronic behavior deviates from the typical insulating nature of many binary lithium oxides. The compound is currently identified as being above the thermodynamic stability hull, suggesting it is a metastable phase. Despite its challenging stability profile, it remains a subject of interest in structural research, with multiple reported configurations documented across materials databases.
Key Properties
Cross-validated computational properties for Sr2LiO12, 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.

How It Compares
Within the lithium oxides class.
Unlike standard battery cathode materials such as LiCoO2 or LiNiO2 which are optimized for electrochemical stability and ion mobility, Sr2LiO12 exhibits a semimetallic character that distinguishes it from the insulating or semiconducting behavior seen in Li2O or Li4SiO4. Its structural complexity and metastability contrast with the highly stable, well-characterized frameworks of the common lithium manganese and titanium oxides.
