A review on hexacyanoferrate-based materials for energy storage and smart windows: challenges and perspectives

With the unprecedentedly increasing demand for renewable and clean energy sources, the sodium‐ion battery (SIB) is emerging as an alternative or complementary energy storage candidate to the present commercial lithium‐ion battery due to the abundance and low cost of sodium resources. Layered transition metal oxides and Prussian blue analogs are reviewed in terms of their commercial potential as cathode materials for SIBs. The recent progress in research on their half cells and full cells for the ultimate application in SIBs are summarized. In addition, their electrochemical performance, suitability for scaling up, cost, and environmental concerns are compared in detail with a brief outlook on future prospects. It is anticipated that this review will inspire further development of layered transition metal oxides and Prussian blue analogs for SIBs, especially for their emerging commercialization.

“…Many review papers have provided insights into this field from diverse perspectives: synthetic strategies, [10][11][12][13][14][15][16][17] structural diversity, [18][19][20][21][22][23] product compositions, [24][25][26][27] and potential applications. [49][50][51][52][53][54][55][56][57] For example, when applied in rechargeable batteries, the available channels and rigid structure of the open framework make PBA materials a kind of excellent cathode materials with fast charge transfer kinetics and long cycle life. [44,45] As a result, PB and PBA materials find promising applications in catalysis, [46,47] photothermal therapy, [48] information storage, [37] sensor, [38] and energy storage and conversion.…”

Due to their special structural characteristics, hollow structures grant fascinating physicochemical properties and widespread applications, especially in electrochemical energy storage and conversion. Recently, the research of Prussian blue (PB) and its analog (PBA) related nanomaterials has emerged and has drawn considerable attention because of their low cost, facile preparation, intrinsic open framework, and tunable composition. Here, the recent progress in the study of PB- and PBA-based hollow structures for electrochemical energy storage and conversion are summarized and discussed. First, some remarkable examples in the synthesis of hollow structures from PB- and PBA-based materials are illustrated in terms of the structural architectures, i.e., closed single-shelled hollow structures, open hollow structures, and complex hollow structures. Thereafter, their applications as potential electrode materials for lithium-/sodium-ion batteries, hybrid supercapacitors, and electrocatalysis are demonstrated. Finally, the current achievements in this field together with the limits and urgent challenges are summarized. Some perspectives on the potential solutions and possible future trends are also provided.

“…Among the multitudinous electrode materials for aqueous SIBs, Prussian blue analogs (PBAs) featured by robust three‐dimensional open framework have received extensive attention. Compared to other electrode materials such as polyanion compounds and transition metal oxides which need high temperature calcination, PBAs also take advantages of their low‐cost, mild and environmentally friendly synthetic procedure . Energy storage in PBAs is based on the redox reaction of either one or both the transition metals along with the ion insertion .…”

“…Compared to other electrode materials such as polyanion compounds and transition metal oxides which need high temperature calcination, PBAs also take advantages of their low-cost, mild and environmentally friendly synthetic procedure. [5,9,13,14,15] Energy storage in PBAs is based on the redox reaction of either one or both the transition metals along with the ion insertion. [13] In addition, the electrochemical properties of PBAs can be effectively tuned via partially or totally replacing the transition metals, making them adaptable for multiple applications.…”

Aqueous rechargeable sodium‐ion batteries have received great attention as an alternative to meet the growing demand of large‐scale electrochemical energy storage systems due to the earth‐abundant and low‐cost sodium resources. In this study, an all Prussian‐blue‐based aqueous sodium‐ion battery is constructed using copper and iron‐based Prussian blue analogues as cathode and anode, respectively, and neutral NaNO3 solution as electrolyte. The battery delivers an average output voltage of 0.70 V, a specific capacity of 50 mAh g−1, and good rate capability with ∼86 % capacity retention over 250 cycles at 5 C. Moreover, the cathode, anode, and electrolyte materials are inexpensive, environmentally friendly, and inherently safe, which is particularly attractive for large‐scale energy storage applications.
