“…Aqueous rechargeable zinc‐ion batteries (ZIBs) have become one of the most potential electrochemical energy storage devices due to their high energy density, low cost, environmental friendliness, and safety. [ 1–3 ] In terms of energy storage mechanism, compared to monovalent metal ions (such as Li + , Na + ), Zn 2+ allows multiple ionic charges to transport carriers. [ 4,5 ] However, practical application of ZIBs is plagued by the obstacles in cathodes, such as poor cycle stability caused by irreversible lattice distortion and low rate caused by poor conductivity.…”

Aqueous rechargeable Zn–MnOx batteries are very attractive due to their low‐cost and high energy density. However, Mn(III) disproportionation and Jahn–Teller distortion can induce Mn(II) dissolution and irreversible phase changes, greatly deteriorating the cycling life. Herein, a multi‐valence cobalt‐doped Mn3O4 (Co‐Mn3O4) with high capacity and reversibility, which lies in the multiple roles of the various states of doped cobalt, is reported. The Co2+ doping between the phase change product δ‐MnO2 layer acts as a “structural pillar,” and the Co4+ in the layer can increase the conductivity of Mn4+ and hold the high specific capacity. More importantly, Co ion (Co2+, Co3+) doping can effectively inhibit the Jahn–Teller effect in discharge products and promote ion diffusion. Using X‐ray absorption spectra results and density functional theory modelling, the multiple roles of doped cobalt are verified. Specifically, the Co‐Mn3O4 cathode shows high specific capacity of 362 mAh g–1 and energy density of 463.1 Wh kg–1 at 100 mA g–1. After 1100 cycles at 2.0 A g–1, the capacity retention rate reaches 80%. This work brings a new idea and approach to the design of highly reversible Mn‐based oxides cathode materials for Zn‐ion batteries.

Rechargeable mild aqueous zinc batteries have recently attracted tremendous interest for large‐scale grid storage due to their potentially highest energy density and safety, and lowest cost among available aqueous battery technologies. Herein, a variety of cathode materials, zinc anode structures, and electrolytes are briefly reviewed. A multi‐type of charge carriers such as Zn2+, H+, and anions can be reversibly stored in cathodes in rechargeable mild aqueous zinc batteries. The charge storage behavior in cathodes and strategies to address the reversibility and dendrite growth of zinc anodes are comprehensively summarized. Solutions to the remaining challenges such as long‐term stability and economy of cathodes and zinc anodes are discussed. This review also includes an analysis of mild aqueous zinc battery chemistry with reported cathode materials and anode materials. A perspective for the practical development of rechargeable mild aqueous zinc batteries regarding cathode design, zinc anode utilization, and cell configuration is also included to accelerate the commercialization of zinc batteries. In the future, rechargeable mild aqueous zinc batteries would be a visible energy storage solution for grid storage.

“…Not only VO2 (B) was demonstrated for ZIBs, recently Zhang et al demonstrated VO 2 (M) can be a suitable choice cathode for ZIB. [104] A binder-free cathode was prepared using VO 2 (M) and CNTs which showed 248 mAh g −1 of specific capacity at 2 A g −1 of current, good rate capability, and superior cyclic stability up to 5000 cycles (84.5% retention in specific capacity at 20 A g −1 of current). Authors also studied the energy storage mechanism which was as same as explained by Li et al [101c] However, herein authors showed that VO 2 (M) phase can also be a potential cathode for ZIBs.…”

Vanadium dioxide (VO2) received tremendous interest lately due to its unique structural, electronic, and optoelectronic properties. VO2 has been extensively used in electrochromic displays and memristors and its VO2 (B) polymorph is extensively utilized as electrode material in energy storage applications. More studies are focused on VO2 (B) nanostructures which displayed different energy storage behavior than the bulk VO2. The present review provides a systematic overview of the progress in VO2 nanostructures syntheses and its application in energy storage devices. Herein, a general introduction, discussion about crystal structure, and syntheses of a variety of nanostructures such as nanowires, nanorods, nanobelts, nanotubes, carambola shaped, etc. are summarized. The energy storage application of VO2 nanostructure and its composites are also described in detail and categorically, e.g. Li‐ion battery, Na‐ion battery, and supercapacitors. The current status and challenges associated with VO2 nanostructures are reported. Finally, light has been shed for the overall performance improvement of VO2 nanostructure as potential electrode material for future application.
