    Sodium Vanadium Phosphate NVP High Rate Polyanion Sodium Ion Battery Positive Electrode

    Sodium Vanadium Phosphate NVP Long Life High Rate Polyanion Sodium Ion Battery Positive Electrode Material


    ​Introduction​

    Sodium Vanadium Phosphate (Na₃V₂(PO₄)₃, NVP) is a ​​polyanionic cathode material​​ widely used in sodium-ion batteries (SIBs). It exhibits ​​excellent structural stability, high operating voltage, and long cycle life​​, making it a promising candidate for ​​large-scale energy storage applications​​.

    ​Key Features​

    1. ​Chemical Formula​​: Na₃V₂(PO₄)₃ (NVP)
    2. ​Crystal Structure​​: NASICON-type (3D open framework)
      • Provides ​​fast Na⁺ ion diffusion​​ due to interconnected channels.
      • Ensures ​​structural stability​​ during charge/discharge cycles.
    3. ​Electrochemical Performance​
      • ​High Voltage​​: ~3.4 V vs. Na⁺/Na (due to V³⁺/V⁴⁺ redox couple).
      • ​Theoretical Capacity​​: 117.6 mAh/g (practical capacity ~110 mAh/g at 0.1C).
      • ​Excellent Rate Capability​​: Retains >90% capacity at 1C rate.
      • ​Long Cycle Life​​: >1000 cycles with minimal capacity degradation.
    4. ​Physical Properties​
      • ​Appearance​​: Black powder.
      • ​Particle Size (D50)​​: 15.00±5.00 μm.
      • ​Tap Density​​: ~1.00 g/cm³ (suitable for electrode fabrication).
      • ​Moisture Sensitivity​​: Low (≤1000 ppm).
