“…Apparently, the normalized intensity of Na 1s region at fully charged and discharged states was lower than that of the original state (Figure b), implying that Na + deintercalation was an irreversible process. On the other hand, as presented in Figure c, the vanadium valence in the pristine NVP was fitted to V 3+ signal (517.0 eV), and it evolved into a mixed state of V 3+ and V 4+ (517.9 eV) after full charging . On the subsequent discharging process, V 4+ was fully reduced to V 3+ , indicating highly reversible V 3+ /V 4+ redox reaction in NVP.…”

“…For instance, NVP nanoparticles wrapped by graphene‐like carbon shown a high voltage platform of 1.46 V verse Zn/Zn 2+ , but suffered from poor zinc storage property (e. g., showing only 74% capacity retained after merely 100 cycles at a low rate 0.5 C) . NVP@rGO microspheres have short cycle life (∼75% capacity retention after 200 cycles at 0.05 A g −1 ) when used in aqueous ZIBs . Another related work was the C−G−NVP synthesized by Huang's group.…”

Aqueous zinc-ion batteries (ZIBs) have become the highest potential energy storage system for large-scale applications owing to the high specific capacity, good safety and low cost. In this work, a NASICON-type Na 3 V 2 (PO 4 ) 3 cathode modified by a uniform carbon layer (NVP/C) has been synthesized via a facile solid-state method and exhibited significantly improved electrochemical performance when working in an aqueous ZIB. Specifically, the NVP/C cathode shows an excellent rate capacity (e. g., 48 mAh g À 1 at 1.0 A g À 1 ). Good cycle stability is also achieved (e. g., showing a capacity retention of 88% after 2000 cycles at 1.0 A g À 1 ). Furthermore, the Zn 2 + (de) intercalation mechanism in the NVP cathode has been determined by various ex-situ techniques. In addition, a Zn j j NVP/C pouch cell has been assembled, delivering a high capacity of 89 mAhg À 1 at 0.2 A g À 1 and exhibiting a superior long cycling stability.

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 ...
