Prussian Blue Na2Fe[Fe(CN)6] Powder for Na-Ion Battery Cathode, 20 g/bottle, CSIBCPB

Prussian blue and its analogues are emerging as promising cathode materials for sodium-ion and zinc-ion batteries due to their unique properties and electrochemical performance. They are distinguished by their open-framework structure which enables fast, reversible insertion and extraction of large ions like Na+ with minimal structural change. Moreover, the "Zero Strain" feature enable the crystal structure generally remains stable with minimal volume change during the Na+ intercalation/deintercalation process, which contributes to excellent cycle life.
