“…Double pairs of predominant peaks can be observed at 0.72/0.57 and 1.10/0.86 V, and a pair of small peaks appears at 1.40/1.28 V. The results of CV curves are well consistent with the discharge–charge profiles shown in Figure b. These redox peaks in CV curves are ascribed to the valance changes from V 5+ to the lower valence states (V 4+ and V 3+ ), demonstrating the multistep insertion/extraction process of Zn 2+ . After initial cycle, the reduction peak located at 0.84 V slightly shifts to 0.86 V, which can be attributed to the gradual activation of the electrode.…”

Lamellar V5O12·6H2O nanobelts coupled with inert Zn(OH)2·0.5H2O are in situ fabricated via a facile hydrothermal strategy. Herein, the inert Zn(OH)2·0.5H2O phase acts as a buffer matrix to strengthen the structural stability of V5O12·6H2O host material, relieving the severe volume variation. Therefore, benefiting from the large interplanar spacing of active V5O12·6H2O and volume buffering effect of inert Zn(OH)2·0.5H2O, V5O12·6H2O/Zn(OH)2·0.5H2O hybrid (denoted as Z‐V5O12·6H2O) sustainably endures the repetitive Zn2+/Na+ insertion/extraction and boosts the electrochemical properties. As cathodes for aqueous zinc‐ion batteries, the Z‐V5O12·6H2O hybrid shows a high discharge capacity of 328 mAh g−1 at 50 mA g−1 and keeps 146 mAh g−1 at 1 A g−1 after 1000 cycles. For nonaqueous sodium‐ion batteries, the hybrid also furnishes a high initial discharge capacity of 241 mAh g−1 at a current density of 50 mA g−1 and maintains 97 mAh g−1 at 100 mA g−1 after 100 cycles.

“…Apart from the Zn 2+ insertion mechanism involved in the above studies, the proton insertion mechanism was also investigated by Liu et al They prepared V 10 O 24 •12H 2 O(VOH) with a layered www.advsustainsys.com structure by a simple hydrothermal method and employed it as the negative electrode. [70] Through the study of the phase and morphology evolutions, a Zn 2+ ion and proton insertion mechanism was proposed. As shown in Figure 3g, the discharge process is divided into the ranges of 1.5-0.8 and 0.8-0.5 V for further discussion.…”

development, but these energy sources have geographical limitations and instability, so it is difficult to achieve a wide range of applications. As an important part of sustainable energy development, electrochemical energy storage has become an area of active research in recent decades. [7-10] In the current energy market, lithium ion batteries (LIBs) are dominant in the automobile, medical equipment, and portable wearable device industries, among others, which can be attributed to their outstanding energy density and environmental protection performance. [11,12] However, the use of organic solvent-based electrolytes may raise safety issues and increase costs. [13-19] Therefore, the creation of an efficient battery system is very important. Compared with nonaqueous batteries, aqueous rechargeable batteries have the characteristics of low cost, nontoxicity, and incombustibility, and are more economically competitive than lithium technology in terms of largescale deployment. [20-22] Therefore, the most important task at present is to develop an ideal battery device with low cost, acceptable safety, long cycle performance, and environmental friendliness as a substitute for LIBs. [23-25] For the past few years, ion batteries with polyvalent metals as the negative electrodes have attracted much attention. Polyvalent cations (Zn 2+ , Mg 2+ , Al 3+) transfer twice or even three times as many electrons into the main material as monovalent cations (Li + , Na +), and each polyvalent positive ion can be inserted into the main compound. [26-32] Theoretically, the capacity of the host material depends on the number of transferred electrons coexisting with the intercalated ions, such that multivalent positive ions have higher weight capacity and energy density. [33] Notably, the element zinc (Zn) has become a common choice for a negative electrode material, owing to its ample sources, low price, low redox potential (−0.76 V vs standard hydrogen electrode), and high surface capacity. [34,35] The mixture of aqueous solution and/or aqueous solution and organic-based electrolyte has emerged as a new research field. Therefore, aqueous zinc ion batteries (ZIBs) have been widely considered for their advantages of high safety, low price, ecological friendliness, and high theoretical capacity. [36] Typically, aqueous ZIBs consist of a Zn metal negative electrode, an aqueous electrolyte that accounts for a majority of the battery material, and a positive electrode containing Zn 2+ ions. [37] A survey has revealed that the conventional With the increasing dependence on high power equipment, there is an urgent need to develop advanced and sustainable energy systems. As one of the main energy storage devices, battery research should make great efforts to implement the sustainable development strategies on ecological, clean and environmentally friendly energy. Currently, aqueous zinc ion batteries (ZIBs) have gained much attention owing to their cheapness, abundant resources, high safety, and ecological friendliness. Nevertheless, ZIBs als...

“…It is of grave importance to find suitable cathode materials for Zn storage. At present, only a few materials are used as cathode electrodes for zinc-ion batteries: (1) Manganese-based materials, [4,[39][40][41][42] (2) Vanadium-based materials, [43][44][45][46][47] (3) Prussian blue analogs-based materials, [48] (4) Organic electrodes, [49,50] (5) Other Cathode Materials. [51,52] MnO 2 , as a representative energy storage material, has been widely concerned due to the structural tunability and Zn 2 + storage in ZIBs.…”

The yolk‐shell structure exhibits fascinating and important properties for energy storage devices. The carbon shell significantly improves the good electrical conductivity and the stable micro‐/nanostructures of the active material increases utilization. MnO2@C with a yolk‐shell structure shows high reversibility, good rate performance, and excellent cycling stability for aqueous Zn‐ion batteries. The Zn‐ion battery with MnO2@C could realize a high reversible capacity of 239 mAh g−1 at 0.1 A g−1. In particular, at a quite high current density of 2 A g−1, it achieves capacity of 91 mAh g−1. The Zn‐ion battery has excellent capacity retention of up to 1000 cycles at 1 A g−1. The yolk‐shell structure plays an important role in improving the battery performance.
