About Li3Co4SnO8
Li3Co4SnO8 belongs to the class of layered lithium transition-metal oxides, characterized by its semiconducting electronic structure. As a metastable phase, it represents a complex arrangement of lithium, cobalt, tin, and oxygen atoms that offers unique structural pathways for ion mobility within the crystal lattice.
This material is of significant interest in materials science due to its potential for tuning electrochemical properties through the substitution of tin into the cobalt-based framework. Its structural complexity and metastable nature make it a compelling subject for researchers aiming to optimize performance in next-generation energy storage systems.
Key Properties
Cross-validated computational properties for Li3Co4SnO8, 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.
