NaFePO4 is a stable, insulating transition-metal phosphate being researched as a sustainable cathode material for sodium-ion batteries.
About maricite
NaFePO4 is a transition-metal phosphate that exists as a thermodynamically stable phase on the convex hull. As a wide-band-gap insulator, its electronic properties are characteristic of its structural framework, which has been extensively documented across multiple databases. Its stability and composition make it a significant subject of study for advanced electrochemical applications.
This compound plays a critical role in the development of sustainable battery technologies. By leveraging the abundance of sodium, researchers utilize this material to explore high-performance cathode alternatives that could potentially reduce reliance on scarcer elements in energy storage systems.
Key Properties
