attention. [9][10][11] AZIBs are considered as one of the most ideal candidates for largescale energy storage owing to their following advantages:i) The excellent properties of zinc: According the data in Table 1, the abundance of zinc in the earth's crust is 79 ppm, and ranks fourth in the world metal production, so zinc has a low market price. Zn metal anode has good electrical conductivity (5.91 µΩ cm), high volumetric energy density (5851 mAh cm −3 ), high theoretical capacity (819 mAh g −1 ), and relatively low redox potential (−0.76 V vs standard hydrogen electrode) which is more suitable in aqueous solution. In addition, multivalent zinc ion can transfer two electrons to facilitate more energy storage than the univalent batteries. [12] At the same time, the ionic radius of zinc ions is 0.74 Å, which is smaller than that of sodium ions (1.02 Å) and close to that of lithium ions (0.69 Å). Moreover, zinc is the essential trace element for human body. [9] In brief, Zn has the superiorities of low cost, low-toxicity, abundant resource, easily recycle, and environmental friendliness.ii) The higher ionic conductivity and safety of aqueous electrolytes: The aqueous electrolytes offer two orders of higher magnitude ionic conductivities (≈1 S cm −1 ) than that of organic electrolytes (≈10 −2 -10 −3 S cm −1 ), so aqueous battery usually has higher power density. [3,13] Meanwhile, the organic electrolytes are usually toxic and flammable, while the aqueous electrolytes are nontoxic and safe, which can mitigate the environmental disruption and recycling costs. iii) The facile assembly process: AZIBs can be assembled in the air condition owing to the stability of zinc anode and aqueous electrolyte. Compared with the batteries assembled in the inert-gas glove box, the manufacturing costs of ZIBs are greatly reduced. The facile manufacture and recycling of AZIBs is an important advantage in the large-scale storage applications.Combining the above advantages, low-cost, safe, and green next-generation AZIBs are suitable specifically for large-scale stationary storage applications. So far, AZIBs are still at the infancy stage. The related researches mainly focused on cathode materials. We count the publication numbers of the reported cathodes for AZIBs in the period from 2012 to February 2019 (1, Supporting Information). As illustrated in Figure 1a, the number of annual publications on cathodes for AZIBs continues to increase rapidly in the recent years. However, in the preliminary stage, Electrochemical energy storage devices will definitely play a vital role in the future energy landscape of the world. The innovation of electrode materials is a key task for the breakthrough of present bottleneck faced by electrochemical energy storage devices. Aqueous zinc-ion batteries (AZIBs) are gaining rapid attention, and they offer tremendous opportunities to explore the low-cost, safe, and next-generation green batteries for large-scale stationary storage applications. In this review, the authors aim to give a comprehensive overview ...

“…In general, ZIB cathode materials have limited capacities, poor capacity retention, poor rate capabilities, limited potential windows, low operating potentials, or a combination of the aforementioned issues. [1,4,5] Presently, several different categories of materials have been explored for use as cathodes, with the most popular ones being V oxide compounds, [4][5][6][7][8][9][10][11][12][13][14] Prussian blue analogues (PBA), [4,5,[15][16][17][18] and Mn oxide compounds. [4,5,[19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] To a lesser extent, sustainable quinone analogs, metal sulfides, Chevrel phase compounds, and polyanion based compounds have also been explored.…”

Nano‐crystalline, flake‐like Mn oxide was electrodeposited onto carbon paper (CP) using a pulsed electrodeposition technique. The electrodeposited Mn oxide was identified as Mn3O4 through a combination of X‐ray photoelectron spectroscopy (XPS), X‐ray diffraction (XRD), and Raman spectroscopy. The Mn3O4 on CP was used as a cathode for Zn‐ion batteries (ZIBs) and showed excellent cyclability at a current density of 1 A g−1 with a capacity retention of 139 % after 200 cycles. Electron microscopy was used to characterize the microstructural changes of the cathode at various stages during discharge/charge cycling. This work in combination with the electrochemical results suggests a two‐step reaction mechanism involving both intercalation and conversion reactions. The results demonstrate that electrodeposition of the cathode material is a simple, quick, and potentially scalable electrode synthesis method for producing high performing Zn‐ion electrodes without the use of binders or other additives.
