Prussian Blues as a Cathode Material for Lithium Ion Batteries

Abstract

Prussian blues (or iron cyanides) and their analogues are attractive in both fundamental studies and industrial applications owing to their chemical and structural diversity. The large open space in their framework provides tunnels and space for the transport and storage of lithium ions. Two Prussian blues were synthesized by a co-precipitation method. The nanosized Fe4 [Fe(CN)6 ]3 and cubic FeFe(CN)6 deliver reversible capacities of 95 mAh g(-1) and 138 mAh g(-1) , respectively. In comparison, FeFe(CN)6 shows cycling and rate performances superior to Fe4 [Fe(CN)6 ]3 .

“…1(e). The water content of PBN 0.4 C 0.6 is determined to be 10.3%, which is less than that of common PBAs [21]. Thus, this indicates an improved thermal stability of PBN 0.4 C 0.6 .…”

“…FeFe(CN) 6 was tested as a cathode material for Li‐ion batteries, delivering a charge capacity of 95 mAh g −1 . The charge–discharge curves showed that the main redox peak at 2.8/3.1 V corresponds to reduction/oxidation of low‐spin Fe 2+ /Fe 3+ ions coordinated with the carbon, and a small redox peak at 3.8/3.9 V was assigned to the reduction/oxidation of the high‐spin Fe 2+ /Fe 3+ bonded to nitrogen (Figure a).…”

“…The phase structure and relative crystallinity of the as-prepared samples were first investigated by taking XRD measurements. 23,24 The absorption bands located at 604 and 502 cm À1 can be assigned to the in-plane and out-of-plane deformations of the Fe-C bond, respectively. S1, ESI †).…”
