“…[ 21 ] Cai et al prepared two different KFeHCFs using K 4 Fe(CN) 6 and K 3 Fe(CN) 6 as the iron‐sources respectively, the former showed a better crystallinity and cycling stability in aqueous NIBs. [ 113 ] Li et al studied the influence of HCl concentration (ascorbic acid coexisted) on the morphology, stoichiometry and electrochemical performances of KFeHCFs in aqueous KIBs. [ 112 ] As shown in Figure 8c–h, with an increase of the HCl concentration from 0 to 2.0 m , the morphology of KFeHCFs changes from well‐crystallized microcuboids (≈1 µm) to poor‐crystallized and agglomerated nanoparticles (≈20 nm).…”

Na‐ion batteries (NIBs) and K‐ion batteries (KIBs) are promising candidates for next‐generation electric energy storage applications due to their low costs and appreciable energy/power density compared to Li‐ion batteries. In the search for viable electrode materials for NIBs and KIBs, Prussian blue analogs (PBAs) with inherent rigid and open frameworks and large interstitial voids have shown an impressive ability to accommodate big alkali‐metal ions without structure collapse. In particular, hexacyanoferrates (HCFs) utilizing abundant Fe(CN)6 resources are the most interesting subgroup of PBAs, being able to deliver a specific capacity of 70–170 mAh g‒1 and a voltage of 2.5‒3.8 V in NIBs/KIBs. In this Review, a comprehensive discussion of the HCF‐type cathode materials in terms of their structural features, redox mechanisms, synthesis control, and modification strategies based on research advances over the last ten years. The methodologies and achievements in improving the material properties of HCFs including the compositional stoichiometry, crystal water, crystallinity, morphology, and electrical conductivity are outlined, with the aim to promote understanding of these materials and provide new insights into future design of PBAs for advanced rechargeable batteries.

“…In a recent work, high‐quality iron hexacyanoferrate nanocubes (HQ‐PB NCs), reported by Cai et al, were investigated as a cathode electrode material for ASIBs . Two couples of well‐separated redox peaks are observed in the CV curve in aqueous 1 m Na 2 SO 4 electrolyte, involving the reversible insertion/extraction reactions of two Na + ions, as shown in Figure 22 a.…”

LIBs), flow batteries like Ni-MH, Ni-Cd and Pb-acid, Na/NiCl 2 , Na-S, Li-O 2 , and Li-S batteries have been considered as potential energy storage devices for ESSs. [5][6][7] The flow batteries like Ni-MH, Ni-Cd, and Pb-acid were feasible in past, whereas the environment pollution and safe risk caused by these batteries have deviated away from the parameters of ESSs. Although the Li-O 2 and Li-S batteries appear to offer the great hope for ESSs by virtue of extremely high energy density, the extensive material challenges and barriers involving electrodes, electrolytes, interfaces, and additive materials could have a profound effect on stabilizing electrode-electrolyte interactions. [8] The practical application of Li-ion batteries has attracted enormous attention and realized in portable devices due to their high energy density and long cycle, and the Li-ion aqueous systems can be a possible substitute for conventional aqueous rechargeable systems such as Ni-MH, Ni-Cd, and Pb-acid since the first aqueous Li-ion battery (ALIB) developed by Dahn and coworkers in 1994. [9][10][11] However, there are some intrinsic characteristics including the growing price of Li resources and safety to make the current LIBs less attractive for large-scale stationary ESSs.Compared with Li, sodium (Na) is the sixth most abundant element in the earth's crust, making it be investigated as a guest ion to develop less expensive and easy accessibility of Na rechargeable battery systems. The early research has focused on high-temperature Na rechargeable battery systems such as Na/NiCl 2 and Na-S batteries, but the safety issue of molten Na and sulfur at 300-350 °C in Na-S batteries is also a remarkable problem for large-scale applications. [6] Aqueous sodium-ion batteries (ASIBs) offer multiple advantages such as wide abundance in the earth's crust, a Sodium (Na) is one of the more abundant elements on earth and exhibits similar chemical properties as lithium (Li), indicating that Na could be applied to a similar battery system. Like aqueous Li-ion batteries, aqueous sodium-ion batteries (ASIBs) are also demonstrated to be one of the most promising stationary power sources for sustainable energies such as wind and solar power. Compared to traditional nonaqueous batteries, ASIBs may solve the safety problems associated with the highly toxic and flammable organic electrolyte in the traditional lithium-ion and sodium-ion batteries. During the past decades, many efforts are made to improve the performance of the ASIBs. The present review focuses on the latest advances in the exploration and development of ASIB systems and related components, including cathodes, anodes, and electrolytes. Previously reported studies are briefly summarized, together with the presentation of new findings based on the electrochemical performance, cycling stability, and morphology approaches. In addition, the main opportunities, achievements, and challenges in this field are briefly commented and discussed. www.advancedsciencenews.com seemingly unlimited distributi...

SummaryNon-lithium energy storage devices, especially sodium ion batteries, are drawing attention due to insufficient and uneven distribution of lithium resources. Prussian blue and its analogs (Prussian blue analogs [PBAs]), or hexacyanoferrates, are well-known since the 18th century and have been used for hydrogen storage, cancer therapy, biosensing, seawater desalination, and sewage treatment. Owing to their unique features, PBAs are receiving increasing interest in the field of energy storage, such as their high theoretical specific capacity, ease of synthesis, as well as low cost. In this review, a general summary and evaluation of the applications of PBAs for rechargeable batteries are given. After a brief review of the history of PBAs, their crystal structure, nomenclature, synthesis, and working principle in rechargeable batteries are discussed. Then, previous works classified based on the combination of insertion cations and transition metals are analyzed comprehensively. The review includes an outlook toward the further development of PBAs in electrochemical energy storage.
