PW Prussian White Powder

Overview

Prussian White (PW) is the fully reduced, sodium-rich analogue of Prussian Blue and is widely recognised as a benchmark cathode active material for sodium-ion batteries (SIBs). Chemically represented as Na₂Fe[Fe(CN)₆], Prussian White features an open-framework cubic crystal structure that enables rapid and reversible sodium-ion intercalation and de-intercalation during electrochemical cycling.

The electrochemical activity originates from the reversible redox transitions of iron centres within the cyanide-bridged lattice, allowing stable Na⁺ storage at moderate operating voltages with excellent structural robustness.

Key Material Features

• Fully sodiated Prussian blue analogue with high initial sodium content
• Open 3D framework promoting fast Na⁺ diffusion
• High structural stability with minimal volume change during cycling
• Good electronic and ionic transport pathways
• Compatible with aqueous and non-aqueous electrolyte systems

Material Characteristics and Compatibility

PW cathode powder is typically supplied with controlled particle morphology and phase purity, making it suitable for electrode fabrication using standard slurry-casting methods. It is fully compatible with common sodium-ion battery research workflows, including:

• Coin cells and pouch cells
• Half-cell and full-cell configurations
• Electrochemical characterisation using potentiostats and battery cyclers
• Structural and morphological analysis via XRD, SEM, and Raman spectroscopy

Typical Applications

• Sodium-ion battery cathode development
• Fundamental electrochemical research
• Grid-scale and stationary energy storage studies
• Cost-effective alternatives to lithium-based cathode systems
