LiMnP2O7
LiMnP2O7 is a stable, semiconducting pyrophosphate material explored as a candidate for advanced lithium-ion battery cathodes.
About LiMnP2O7
LiMnP2O7 belongs to the phosphate-based cathode family, characterized by its semiconducting electronic nature and robust thermodynamic stability on the convex hull. This material is distinguished by its complex structural chemistry, with numerous reported configurations that make it a significant subject of study in solid-state materials science.
Its role as a potential cathode material stems from the flexibility of the pyrophosphate framework, which supports ion mobility and structural integrity during electrochemical cycling. The compound is primarily investigated for its contribution to developing high-performance lithium-ion battery technologies.
Key Properties
Cross-validated computational properties for LiMnP2O7, 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.
