“…Ketjen black (KB) is an efficient conducting additive for PB electrodes due to its large surface area and high conductivity. [ 151 ] With addition of KB in the self‐decomposition precursor solution, Jiang et al prepared a NaFeHCF/KB composite in which the NaFeHCF could nucleate and grow tightly on the large surfaces of KB ( Figure 15 a). [ 146 ] Compared to the case of no KB addition, the as‐grown NaFeHCF shows much smaller grain size (100‒200 nm vs 0.5‒1.5 µm) and a more favorable composition with lower vacancy and crystal water (Na 0.65 Fe[Fe(CN) 6 ] 0.93 ·2.6H 2 O vs Na 0.52 Fe[Fe(CN) 6 ] 0.85 ·3.15H 2 O).…”

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.

Electrochemical sodium deposition/dissolution behaviors in propylene carbonate-based electrolyte solution were observed by means of in situ light microscopy. First, granular sodium was deposited at pits in a sodium electrode in the cathodic process. Then, the sodium particles grew linearly from the electrode surface, becoming needle-like in shape. In the subsequent anodic process, the sodium dissolved near the base of the needles on the sodium electrode and the so-called "dead sodium" broke away from the electrode. The mechanisms of electrochemical sodium deposition and dissolution on a copper electrode were similar to those on the sodium electrode.Lithium-ion batteries are used for power sources in mobile devices and electric vehicles, and the demand for them is likely to increase. However, since lithium is not an abundant metal, it is expensive 1 . On the other hand, sodium is abundant and cheap, and interest in sodium-ion batteries (SIBs) has been growing 1 . Various materials have been studied for use as a SIB's cathode or anode [2][3][4][5][6][7][8][9][10][11] . Most of these studies have been conducted on a half-cell system comprising a working electrode (WE), a counter electrode (CE), and if necessary, a reference electrode (RE). The WE contains the cathode or anode materials. In general, sodium metal sheets are used for the CE in the half-cell system. Using Na as the anode material is conceivable, but this would be difficult in practice because of safety issues.There are many reports on electrochemical lithium deposition/dissolution [12][13][14][15][16][17][18][19][20][21] . Lithium metal electrodes have drawbacks of short circuiting and poor cyclability due to lithium "dendrite" formed during the electrochemical deposition. As reported in ref. 18 , the process of electrochemical lithium deposition in an electrolyte solution of LiAsF 2 /ethylene carbonate-2-methyltetra-hydrofuran at 0.5 mA/cm 2 is as follows. Lithium grows from the base of the lithium electrode and creates kinks. Consequently, the shape of deposited lithium becomes dendritic. Then, lithium starts to deposit on the tip and at kink points of the lithium dendrite. The shape of the deposited lithium is particle-like. The process of electrochemical dissolution of the lithium dendrite is as follows 18 . The particle-like lithium on the tips and at kink points is dissolved. Then, the base of the dendrite is dissolved and the dendrite becomes "dead lithium". This is a one of the causes of the poor reversibility of lithium metal electrodes. In addition, studies of the shape of electrochemically deposited lithium in various kinds of electrolyte have indicated electrolyte dependence of the shape 22-24 .As describe above, there is accumulated scientific knowledge about electrochemical lithium deposition/dissolution. However, there are few reports 25 on electrochemical sodium deposition/dissolution. It is important to understand behaviors, such as shape change during cycling, reversibility, and coulombic efficiency, to advance the development of SIBs...

Although largely used in mobiles and electric vehicles applications, insertion batteries based on Li-ion technology are high-cost devices. These applications require high-performance energy storage systems with high-energy and high-power densities, which are better attained by Li-ion technology. However, stationary applications such as power plants and uninterruptible power supplies (UPS) mainly require low-cost energy storage devices. In this scenario Na-ion insertion batteries feature as a cheaper option for such applications. Among the several compounds for use as cathode in Na-batteries, a largely studied class of compounds are the sodium-carbonate-phosphates, Na 3 MCO 3 PO 4 (M = Mn, Fe, Co or Ni), with structure analogue to the mineral sidorenkite. In this work, it was developed a new microwave-assisted hydrothermal method as an ultra-fast way to prepare sodium-carbonate-phosphate compounds. This methodology results in high-quality materials with general formula Na 3 MCO 3 PO 4 (M = Mn, Fe, Co or Ni) upon only 5 min processing time. Characterization techniques indicate highly ordered materials with sidorenkite-like phase and different morphologies or crystal habits, including plates, rods, and a 'starfruit' shape. As a proof-of-application the Mn-based material was evaluated from electrochemical tests for Na + insertion reactions. The obtained results evidence initial discharge capacity of 107 mA h g-1 with good reversible capacity (65 mA h g-1) after several charge/discharge cycles.
