“…Besides, oxygen‐deficient Al 3+ ‐doped V 2 O 3 /C was obtained via ion exchange and ensuing annealing. [ 132 ] During the initial charge, Al 3+ ‐doped V 2 O 3 /C would totally transform to Al 3+ ‐doped Zn 3 (OH) 2 V 2 O 7 2H 2 O. It is revealed that the doped Al 3+ in Zn 3 (OH) 2 V 2 O 7 2H 2 O made for lower binding energy and diffusion of Zn 2+ , leading to good rate performance and long‐term cycling stability.…”

However, the organic electrolytes used in LIBs are highly toxic and flammable, and are deemed safety hazards. The limited resources and high-cost of lithium and harsh assemble conditions of LIB cells also hinder the application of LIBs in large-scale energy storage systems. [2] P. Rüetschi proposed the '3 E' criteria including Energy, Economics, and Environment to determine whether the battery system was practical for daily use. [3] Aqueous electrolytes with low price, high safety, and high conductivity can drastically reduce the production cost and improve battery safety. [4] Aqueous zincion batteries (ZIBs) use Zinc as an environment-friendly anode which shows low redox potential (−0.78 eV vs SHE), high electronic conductivity as well as large capacity (820 mAh g −1 and 5851 mAh cm −3 ). [5,6] Therefore, ZIBs are considered as one of the most competitive and promising development directions for next-generation large-scale energy storage. As the initial work in mild aqueous electrolyte, an aqueous ZIB with MnO 2 cathode and Zn anode was reported by Kang and co-workers in 2012. [7] Since then, research interests in ZIBs area develops burgeoningly and more than 1000 research papers about electrode materials on aqueous ZIBs were published.The commonly reported cathode materials are V-based compounds, [8,9] manganese oxides, [10,11] Prussian blue analogs, [12,13] metal chalcogenides, [14,15] and organic compounds. [16,17] Among them, manganese oxides have moderate operating potential and high theoretical capacity, but suffer from manganese dissolution in aqueous electrolytes due to Jahn-Teller dissolution of Mn 3+ , which leads to structural collapse and poor cycling stability. [10,11] Prussian blue analogs often process high operating potential beyond 1.5 V and their open cage-like framework guarantees structure stability under rapid Zn 2+ transmission, leading to good rate performance and long-cycle capacity retention. However, the large framework structures also bring limited theoretical capacity and suffer from O 2 evolution due to the high operating potential. [13,18] Organic cathodes process passable theoretical capacity, high structural diversity, and flexibility, bringing potential prospects in flexible electrodes. But the high dissolubility in electrolytes and high resistance are two bumps to overcome for organic cathodes used in ZIBs. [16,17] V-based compounds have received extensive attention as cathode for ZIBs due to the rich reserves and diversity of valences of vanadium as well as their general high theoretical capacity and Aqueous zinc-ion batteries (ZIBs) have been promptly developed as a competitive and promising system for future large-scale energy storage. In recent years, vanadium (V)-based compounds, with diversity of valences and high electrochemical-activity, have been widely studied as cathodes for aqueous ZIBs because of their rich reserves and high theoretical capacity. However, the stubborn issues including low conductivity and sluggish kinetics, plague their smooth application in aqueous...
