Materials for aqueous sodium-ion batteries: cation mobility in a zinc hexacyanoferrate electrode

Abstract

The coordination polymer Zn3Na2[FeII(CN)6]2 has an open porous framework that is stable in acidic and neutral aqueous solutions and appears to be an attractive solid for investigation as a material for sodium ion-based batteries.

On the Scope of XPS as Sensor in Coordination Chemistry of Transition Metal Hexacyanometallates

“…The net effect is an overlapping for the electron clouds of the involved metals (M, T). This explains the attractive properties of this family of materials as prototype of molecular magnets, which have been widely studied in the last decades The presence of two redox centers linked through the CN bridge and for some compositions also of an exchangeable alkali metal (A), has stimulated their study as materials for new generation of batteries, in electrochemical sensors, environmental remediation,, and for health care . For certain combinations of metals, e.g.…”

“…for new generation of batteries, [4][5][6] in electrochemical sensors, [7][8][9] environmental remediation, [10,11] and for health care. [12] For certain combinations of metals, e.g.…”

“…Twenty compositions of transition metal cyanides were considered in this study. For TK 2 6 ] were included in this study in order to evaluate the scope of XPS to obtain fine details on the CN π-back bonding effect in hexacyanometallates and its role in the properties of their coordination polymers. The results herein discussed, from XPS data, are appropriately supported by IR spectra and structural studies for the materials under study (Supporting Information).…”

A High‐Energy Aqueous Sodium‐Ion Capacitor with Nickel Hexacyanoferrate and Graphene Electrodes

“…Alternatively, two dimensional materials such as layered MoS 2 , MoSe 2 , TiS 2 , and MXene, are recently explored as Na‐ion intercalative pseudocapacitive materials ,. In this scenario, metal organic framework mimicking metal hexacyanoferrate have been studied as electrode materials for Na‐ion batteries and capacitors ,. The metal hexacyanoferrate possess the Prussian blue crystal structure which can intercalate variety of ions such as Li + , and Na + during electrochemical charge‐discharge cycles .…”

“…[12,13] In this scenario, metal organic framework mimicking metal hexacyanoferrate have been studied as electrode materials for Na-ion batteries and capacitors. [14,15] The metal hexacyanoferrate possess the Prussian blue crystal structure which can intercalate variety of ions such as Li + , and Na + during electrochemical charge-discharge cycles. [16] In a recent work, M. Wan et al demonstrated the superior electrochemical activity of core-shell structured Fe-HCF@Ni-HCF electrodes for sodium ion storage for Na-ion batteries.…”
