VCdPO7
VCdPO7 is a semiconducting transition-metal phosphate containing vanadium and cadmium that exists in a metastable state.
About VCdPO7
VCdPO7 is a complex transition-metal phosphate incorporating vanadium and cadmium. As a semiconducting material, it represents a specialized chemical architecture within the broader family of phosphate-based compounds, characterized by its distinct arrangement of metal-oxygen polyhedra and phosphate groups.
While transition-metal phosphates are frequently investigated for their electrochemical potential, VCdPO7 sits in a metastable state above the thermodynamic hull. This positioning suggests unique synthetic challenges and potential for structural transformation, distinguishing it from more common, highly stable phosphate frameworks.
Key Properties
Cross-validated computational properties for VCdPO7, 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 transition-metal phosphates class.
Unlike the widely utilized and thermodynamically robust battery materials such as LiFePO4 or LiMnPO4, which are prized for their structural stability during ion intercalation, VCdPO7 exhibits a higher energy state. While compounds like TiP2O7 or LiFeP2O7 are often studied for their stable framework architectures, VCdPO7 represents a more exotic member of the class, offering a different structural landscape that contrasts with the well-ordered, stable olivine or pyrophosphate structures found in its more common siblings.
