LiZnPS4
LiZnPS4 is a thermodynamically stable, semiconducting sulfide solid electrolyte used in advanced battery research.
About LiZnPS4
LiZnPS4 is a quaternary sulfide solid electrolyte characterized by its semiconducting electronic nature. As a material that resides on the thermodynamic convex hull, it exhibits excellent structural stability, making it a reliable candidate for investigations into ion transport mechanisms within solid-state battery architectures. Its unique composition of lithium, zinc, phosphorus, and sulfur allows for a distinct atomic arrangement that supports stable electrochemical performance. This compound is primarily utilized in the development of advanced energy storage systems where high stability and efficient lithium-ion conductivity are essential requirements for safety and longevity. By maintaining a robust lattice structure, it serves as a foundational material for researchers aiming to overcome the limitations of traditional liquid electrolytes.
Key Properties
Cross-validated computational properties for LiZnPS4, 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 sulfide solid electrolytes class.
Within the diverse group of sulfide solid electrolytes, LiZnPS4 stands out for its thermodynamic stability compared to more complex or metastable structures like Li14P6S22. While many members of this class, such as the indium-containing Ge2In4Li4S6, are engineered for specific conductivity enhancements, LiZnPS4 provides a simpler, highly stable framework that serves as a benchmark for understanding how zinc incorporation influences the electrochemical window and ion mobility in quaternary sulfide systems.
