LiFePHO5
LiFePHO5 is a thermodynamically stable, semiconducting phosphate compound utilized in the research and development of advanced cathode materials for energy storage.
About LiFePHO5
LiFePHO5 is a complex phosphate material belonging to the olivine-related family of cathode compounds. Characterized by its semiconducting electronic nature, this material maintains robust thermodynamic stability, placing it on the convex hull of its chemical system. Its structural integrity makes it a subject of significant interest for researchers investigating ion-conducting frameworks.
As a member of the phosphate-based cathode class, it serves as a critical model for understanding how protonation and structural variations influence electrochemical behavior. Its presence in multiple structural databases highlights its importance in the ongoing effort to optimize cathode materials for next-generation energy storage applications.
Key Properties
Cross-validated computational properties for LiFePHO5, 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.
