“…This indicates that MnO 2 /GCF has much better cyclability than MnO 2 /CF, but the rechargeable performance of MnO 2 /CF is still better than most of previous reports ,,. Moreover, the long‐term cyclability of MnO 2 /GCF is better than previous reported MnO 2 ‐based materials: MnO 2 /C (69% of the initial value after 50 cycle), Ni‐ and Bi‐doped‐MnO 2 (90% of the initial value after 50 cycles), and MnO 2 nanorods (75% of the initial value after 200 cycles) . Additionally, MnO 2 /GCF after 400‐cycle measurement almost maintains the original hierarchical morphology (Figure S6) and crystalline structure (Figure f) without a big change.…”

MnO2 material has been widely utilized in primary batteries because of its high theoretical capacity, rich resources, and low cost, which, however, does not exhibit satisfactory reversible capacity and cycle life when used as a secondary battery cathode. To upgrade the rechargeability of MnO2 material, we herein fabricated a hierarchical nanocomposite by in‐situ growth of MnO2 nanostructure on carbonized melamine sponge (MnO2/C). The optimized MnO2/C nanostructure consisting of hierarchical nanospikes shows a high reversible capacity of 205 mAh⋅g‐1 at 1 C and retained 96% of its initial capacity after 400 cycles, and even at 5 C (i. e. 1540 mA⋅g‐1), the capacity retention still reaches 90% after 400 cycles, indicative of its remarkable high‐rate cycling stability. This study provides a new avenue for designing high‐rate rechargeable MnO2 cathode and may further advance the development of MnO2‐based secondary batteries.

“…For example, Lian et al [12] introduced the gradient Ti doping on the surface of the α-MnO 2 nanowires, and achieved the Zn/MnO 2 batteries with excellent high-rate capability and ultralong cycling stability. Other similar studies like the α-MnO 2 @C [13] and α-MnO 2 @In 2 O 3 [14] also improved the cycling stability and rate performance of the α-MnO 2 -based AZIBs. The aforementioned studies mainly focused on the protection of the α-MnO 2 nanowires itself, which was highcost and low-efficiency in the scale-up application.…”

Aqueous Zn-ion batteries (AZIBs) are one of the promising battery technologies for the green energy storage and electric vehicles. As one attractive cathode material for AZIBs, α-MnO 2 materials exhibit superior electrochemical properties. However, their long-term reversibility is still in great suspense. Considering the decisive effect of the structure and morphology on the α-MnO 2 materials, hierarchical α-MnO 2 materials would be promising to improve the cycle performance of AZIB. Here, we synthesized the α-MnO 2 urchin-like microspheres (AUM) via a self-assembled method. The porous microspheres composed of one-dimensional α-MnO 2 nanofibers with high crystallinity, which improved the surface area and active sites for Zn 2+ intercalation. The AUMbased AZIB realized a high initial capacity of 308.0 mA h g −1 , and the highest energy density was 396.7 W h kg −1 . The kinetics investigation confirmed the high capacitive contribution and fast ion diffusion of the AUM. Ex-situ XRD measurement further verified the synergistic insertion/extraction of H + and Zn 2+ ions during the charge/discharge process. The superiority of the AUM guaranteed good electrochemical performance and reversible phase evolution, and this application would promote the follow-up research on the advanced AZIB.

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 ...
