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

Chemical Formula: Na₃V₂(PO₄)₃ (NVP)
Crystal Structure: NASICON-type (3D open framework)
- Provides fast Na⁺ ion diffusion due to interconnected channels.
- Ensures structural stability during charge/discharge cycles.
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.
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).
