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.

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.
