Product Description

High-pressure Compaction 2.3 Sodium Iron Pyrophosphate NFPP Sodium Ion Battery Cathode Material Solid-state Sodium Battery

Product Overview​​

High-tap-density (2.3 g/cm³) Na₄Fe₃(PO₄)₂P₂O₇ (NFPP) is an advanced polyanionic cathode material for solid-state sodium-ion batteries, offering exceptional structural stability, high volumetric energy density, and ultra-long cycle life (>4,000 cycles). Its unique 3D open-framework architecture enables efficient Na⁺ diffusion, making it ideal for high-performance solid-state batteries in grid storage and EV applications.

Key Specifications​​

​​Purity​​ ≥99.9% 99.99% (4N grade)
​​Tap Density​​ 2.3 ± 0.1 g/cm³ 2.3 g/cm³
​​Particle Size (D50)​​ 6–12 μm 9 μm
​​Specific Surface Area​​ ≤10 m²/g 8 m²/g
​​0.1C Capacity​​ ≥105 mAh/g 105–110 mAh/g
​​1C Capacity​​ ≥95 mAh/g 95–100 mAh/g
​​Voltage Platform​​ 3.0–3.2 V (vs. Na⁺/Na) 3.1 V
​​Cycle Life​​ >4,000 cycles (100% DoD) >6,000 cycles (80% DoD)
​​Thermal Stability​​ Stable up to 400°C No thermal runaway

Material Advantages​​

  1. ​​High Volumetric Energy Density​​

    • Ultra-high tap density (2.3 g/cm³) enables compact electrode design, critical for solid-state batteries.
    • Theoretical capacity: 129 mAh/g (3 Na⁺ intercalation).

  2. ​​Solid-State Compatibility​​

    • Minimal volume change (<4%) during cycling, reducing interfacial stress with solid electrolytes.
    • Stable with sulfide/oxide solid electrolytes (e.g., Na₃PS₄, Na₃Zr₂Si₂PO₁₂).

  3. ​​Cost-Effectiveness​​

    • Raw material cost: ~3.5k/ton for layered oxides).
    • Low sintering temperature (550–650°C vs. 900°C for oxides).

       

      ​​

    • Safety & Environmental Benefits​.​

    • Non-toxic, non-flammable, and free of critical metals (Co, Ni).
       

Applications​​

  • ​​Solid-State Sodium Batteries​​: Grid-scale storage, EV power packs.
  • ​​Low-Temperature Operations​​: Stable performance at -20°C.
  • ​​High-Safety Systems​​: Aerospace, medical devices.
