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).
