Prussian White Na2Mn[Fe(CN)6] Powder for Na-Ion Battery Cathode, 50-500 g/bottle, CSIBCPW

Prussian white and its analogues Na2Mn[Fe(CN)6] are emerging as promising cathode materials for sodium-ion and zinc-ion batteries due to their open, cubic framework structure that facilitates fast and reversible insertion/extraction of the large Na+. It has the following advantages:

(1) High Working Voltage: The Mn2+/Mn3+ redox couple provides a higher potential plateau (around 3.3 V) compared to the Fe2+/Fe3+ couple in the iron-only analogue (around 3 V). This elevated voltage directly leads to higher energy density for the full battery.

(2) High Capacity: The material utilizes the redox activity of both metal centers, offering a high theoretical specific capacity of approximately 170 mAh/g. Practical capacities often exceed 120 mAh/g.

(3) Low Cost: It is composed of earth-abundant and non-toxic elements (Na, Mn, Fe), making it highly attractive for large-scale energy storage systems.

(4) "Zero Strain" Framework: Like other PBAs, it maintains a relatively stable crystal structure with minimal volume change during cycling, contributing to potentially long cycle life. $ showing the cubic framework and Na+ ion diffusion channels]
