Prussian Blue Cathode Material Sodium Battery Long Cycle High Capacity

Prussian Blue Cathode Material Sodium Battery Long Cycle High Capacity

​Product Overview​​

Prussian Blue (Na₂Fe[Fe(CN)₆]), provided by Xwell, is a ​​research-grade cathode material​​ designed for sodium-ion battery (SIB) applications. Its open framework structure enables ​​fast Na⁺ ion diffusion​​, while the iron-cyanide composition ensures ​​low-cost and high stability​​. This battery-grade powder is ideal for ​​academic research and prototype development​​.

Key Specifications​​

Features & Advantages​​

1. ​​Structural Benefits​​:

   • Cubic crystal framework (Fm-3m space group) with large interstitial sites for rapid Na⁺ insertion/extraction.
   • Theoretical capacity: ~170 mAh/g (V₃⁺/V⁴⁺ redox couple).

2. ​​Performance Highlights​​:

   • ​​High ionic conductivity​​: 10⁻¹⁰–10⁻¹¹ cm²/s Na⁺ diffusion coefficient.
   • ​​Excellent cyclability​​: Minimal phase change during charge/discharge.

3. ​​Manufacturing Edge​​:

   • Synthesized via ​​room-temperature co-precipitation​​ for batch consistency.
   • Low impurity levels (<1% lattice water).

Applications​​

• ​​Academic Research​​: Electrode formulation optimization.
• ​​Prototype Batteries​​: Coin/pouch cell testing.
• ​​Comparative Studies​​: Benchmarking against other SIB cathodes.
