High-Capacity Prussian White (NaₓFe[Fe(CN)₆]) Cathode Material for Sodium-Ion Batteries

1. Introduction

Prussian White (PW, NaₓFe[Fe(CN)₆]) is a low-cost, high-capacity cathode material for sodium-ion batteries (SIBs). As a derivative of Prussian blue analogs (PBAs), it leverages an open framework structure with fast Na⁺ diffusion and excellent structural stability, making it ideal for large-scale energy storage systems.

2. Key Features

Chemical Formula: NaₓFe[Fe(CN)₆] (typically 1.6 ≤ x ≤ 2.0 for full Na⁺ insertion)
Crystal System: Cubic (Fm-3m space group)
Framework: Open 3D channels enable rapid Na⁺ migration (10⁻¹⁰–10⁻¹¹ cm²/s diffusion coefficient).

4. Material Advantages

✅ Ultra-Low Cost: Iron/cyanide-based precursors reduce raw material expenses by ~60% vs. layered oxides.
✅ High Safety: Strong Fe-C≡N bonds suppress thermal runaway risks.
✅ Scalable Synthesis: Simple co-precipitation process (room temperature, aqueous solutions).
