Prussian White Sodium Ion Battery Cathode Material Na2MnFe CN 6 Powder for Advanced Sodium Ion Energy Storage Research

Product Overview

This Prussian white active powder represents a premium-grade sodium-ion battery cathode material, chemically formulated as Na2MnFe(CN)6. Designed specifically for advanced energy storage research and development, the material features a unique three-dimensional open network framework. This robust crystal architecture provides wide interstitial channels that facilitate rapid sodium-ion diffusion and exceptional charge conduction, establishing high electrochemical reversibility during repeated intercalation and de-intercalation cycles.

Optimized for seamless integration into modern laboratory cell fabrication workflows, this active powder is suitable for researchers producing sodium-ion coin cells, pouch cells, and specialized testing prototypes. Its high sodium-rich stoichiometry eliminates the requirement for preliminary pre-sodiumation steps, allowing direct combination with standard sodium-poor or carbon-based anode active materials during electrode preparation, slurry mixing, and precision press consolidation.

Engineered to ensure high operational consistency under demanding electrochemical conditions, this cathode material delivers outstanding structural stability. It maintains minimal lattice strain throughout rapid charge and discharge processes, making it a reliable foundation for evaluating rate capabilities, cycle life, and thermal safety in next-generation sodium-ion battery development.
