“…An ideal curve with well‐defined shape is obtained for the ideal model where NiHCF is assumed to be an ideal solution. This is often not the case as we have reported in our previous publication . The deposition of the film is stopped when the voltammogram becomes stable upon cycling as seen in Figure .…”

“…The peak potential for the reversible insertion of the cations follows the hydrated radii as reported widely in literature. [29,52,53] The difference between the cathodic and the anodic peak (DE p ) for Na + and K + was ca. 60 mV and 80 mV respectively.…”

“…This is often not the case as we have reported in our previous publication. [29] The deposition of the film is stopped when the voltammogram becomes stable upon cycling as seen in Figure 1. The charge consumed on reduction of the electrodeposited NiHCF thin film was calculated from the integral of the cathodic part of the cyclic voltammogram and it was equal to .…”

“…The interest in thin films of Prussian blue derivatives is connected to their fast charging/discharging rates, large ion‐exchange capacities, low cost and low toxicity, which makes them interesting materials in various applications such as electrochemically switched ion exchange (ESIX), ion sensing, electrocatalytic, electrochromic and photo‐magnetic applications . The chemical formula of NiHCF is A n NiFe(CN) 6 , in which A is the intercalated cation . NiHCF has been described as a non‐selective host structure and the reversible insertion of various cations (Li + , Na + , K + , Cs + , NH 4 + ) in this material from single and mixed solutions has been reported …”

“…[24][25][26][27][28] The chemical formula of NiHCF is A n NiFe(CN) 6 , in which A is the intercalated cation. [16,29] NiHCF has been described as a non-selective host structure and the reversible insertion of various cations (Li + , Na + , K + , Cs + , NH 4 + ) in this material from single and mixed solutions has been reported. [30][31][32][33][34][35][36][37][38] The (de-)intercalation of cations in NiHCF has been attributed to the (reduction) oxidation of the iron centers followed by the (de-)insertion of cations in the NiHCF in order to preserve the electroneutrality of the host structure.…”

Dynamic multi‐frequency analysis (DMFA) is capable of acquiring high‐quality frequency response of electrochemical systems under non‐stationary conditions in a broad range of frequencies. In this work, we used DMFA to study the kinetics of (de‐)intercalation of univalent cations (Na+ and K+) in thin films of nickel hexacyanoferrate (NiHCF) during cyclic voltammetry. For this system, the classic stationary electrochemical impedance spectroscopy fails due to the instability of the oxidized form of NiHCF. We are showing that such spectra can be fitted with a physical model described by a simple two‐step intercalation mechanism: an adsorption step followed by an insertion step. The extracted kinetic parameters are depending on the state of charge as well on the nature of the inserted cation.

adaptability for homes, communities, and the grid. [4,5] Although non-aqueous lithium-ion batteries (LIBs) are the technology of choice for electromobility, cost and safety issues caused by the flammable and volatile organic electrolyte hinder their wide application in large-scale stationary applications, [6] in which cost and safety are the determining factors instead of energy density. [7] In this context, rechargeable aqueous batteries, which use non-flammable and less-volatile aqueous electrolytes become appealing alternatives for large-scale stationary applications. [8,9] The first aqueous battery based on LiMn 2 O 4 //VO 2 , featuring a "rocking-chair" mechanism was proposed by Dahn's and co-workers in 1994. [10] The limited electrochemical window of aqueous electrolytes was extended in 2015 by using a "waterin-salt" electrolyte designed by Wang's group, demonstrating a LiMn 2 O 4 //Mo 6 S 8 aqueous LIB with a high output potential of 2.3 V. [11] Beyond aqueous LIBs, other aqueous chemistries based on alternative metallic cations, that is, Na + , [12][13][14] K + , [15,16] Zn 2+ , [17][18][19] Mg 2+ , [20,21] Ca 2+[22] and Al 3+ , [23] are currently being intensively investigated. Alongside, aqueous ammonium-ion batteries (AAIBs) using non-metallic NH 4 + are gradually emerging, driven by the NH 4 + fast diffusion kinetics. [24,25] Indeed, NH 4 + possesses a small hydrated ionic radius (3.31 Å) providing fast diffusion kinetics. [26] Despite some pioneering works [24,27] have demonstrated the potential of this battery chemistry, it is still very challenging to develop a stable full "rocking-chair" AAIB with high coulombic efficiency, due to the instability of electrode materials in the present diluted aqueous electrolytes.To address the above-mentioned challenge, two main strategies can be adopted. The first is to develop novel and stable electrode materials. Among the so far proposed electrode materials, the cost-efficient Prussian blue and its analogues (PBA), owing an open framework and large interstitial sites, have been intensively researched. [28][29][30] In addition, several inorganic materials including Ti 3 C 2 MXenes, [27] V 2 O 5 , [31] TiO 1.85 (OH) 0.30 •0.28H 2 O, [32] Fe 5 V 15 O 39 (OH) 9 •9H 2 O, [33] MoO 3 , [34] VS 2 /VO x , [35] NH 4 V 4 O 10, [36] MnO x , [37,38] as well as organic compounds such as 3,4,9,10-perylene tetracarboxylic diimide (PTCDI), [24] 1,4,5,8-naphthalene tetracarboxylic dianhydride-derived polyimide (PNTCDA), [39] polyaniline [40] and covalent organic frameworks (COFs) [41] have been investigated. Rechargeable aqueous batteriesare promising devices for large-scale energy-storage applications because of their low-cost, inherent safety, and environmental friendliness. Among them, aqueous ammonium-ion (NH 4 + ) batteries (AAIB) are currently emerging owing to the fast diffusion kinetics of NH 4 + . Nevertheless, it is still a challenge to obtain stable AAIB with relatively high output potential, considering the instability of many electrode materials in an aqueous envi...
