Sodium Vanadium Phosphate

Sodium vanadium phosphate (NVP), with the chemical formula Na₃V₂(PO₄)₃, is an air-stable cathode active material designed for sodium-ion batteries. It features a NASICON-type crystal structure with rhombohedral symmetry (space group R3̅c), which promotes efficient sodium-ion conduction through its three-dimensional framework. The material is supplied as a carbon-coated powder to enhance electrical conductivity, with a typical particle size of 12 μm (D50) and a surface area of approximately 30 m²/g. NVP exhibits high thermal stability, with a melting point exceeding 800 °C. Its air stability and favorable electrochemical properties make it an excellent choice for battery manufacturing applications.

Sodium vanadium phosphate (NVP) is a cost-effective and sustainable cathode material ideal for sodium-ion battery research and development. Its NASICON-type crystal structure enables efficient sodium-ion transport, leading to high specific capacities even at fast charging and discharging rates, along with excellent cycling stability. A standout feature of NVP is its flat voltage profile with a plateau at 3.4 V vs. Na/Na⁺, which is relatively higher than that of other cathode materials for sodium-ion batteries, providing enhanced energy density. With a first cycle discharge capacity of approximately 110 mAh/g at 0.1C (between 3.8 V and 2.5 V) and a first cycle efficiency exceeding 90%, our NVP exhibits superior performance suitable for high-energy-demand systems. Additionally, its air stability simplifies handling and processing, reducing manufacturing complexities and costs. These attributes make NVP a great candidate for next-generation, reliable energy storage solutions, including electric vehicles, grid energy storage, and portable electronics.
