LiMnPO4
Lithium manganese phosphate · LMP
LiMnPO4 is a stable, insulating olivine phosphate material primarily investigated for use as a high-voltage cathode in lithium-ion batteries.
About Lithium manganese phosphate
LiMnPO4 is a thermodynamically stable member of the olivine phosphate family, characterized by its wide-band-gap insulating electronic structure. Its structural integrity and electrochemical properties make it a subject of significant interest for advanced energy storage research.
As a highly studied cathode material, it benefits from extensive structural data reported across multiple databases. Its role in the olivine class is defined by its ability to provide higher operating voltages compared to iron-based counterparts, positioning it as a key candidate for next-generation battery technologies.
Key Properties
Cross-validated computational properties for Lithium manganese phosphate, 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.
