Aqueous zinc-ion batteries (AZIBs) lately garner a lot of interest and are viewed as a promising energy storage technology due to their low cost, eco-friendliness, and exceptional safety. Crystal metal oxide cathode research has advanced significantly in recent years, making AZIBs a viable choice for low-cost grid storage applications. However, the readily available (Mn-and V-based oxides) electrode materials suffer from instability and low conductivity. As a consequence, extensive study efforts are dedicated into the development and evaluation of high-performance cathode systems. Herein, advanced composite cathodes with modified structures are reviewed in an attempt to increase capacity and cycle life. The Mn-and V-based composite framework with polymer template, graphene, and MXene induces electric conductivity, improved lattice spacing, and tunable characteristics, as well as possible benefits for overcoming the redox kinetics and stability constraints for AZIBs. As a result, rational modification of the metal oxides as well as the production of composites shows promise in solving problems and improving cathode performance in high-performance AZIBs.

Rechargeable zinc‐ion batteries (ZIBs) with exceptional theoretical capacity have garnered significant interest in large‐scale electrochemical energy storage devices due to their low cost, abundant material, inherent safety, high specific energy, and ecofriendly nature. Metal carbides/nitrides, known as MXenes, have emerged as a large family of 2D transition metal carbides or carbonitrides with excellent properties, e.g., high electrical conductivity, large surface functional groups (e.g., F, O, and OH), low energy barriers for the diffusion of electrolyte ions with wide interlayer spaces. After a decade of effort, significant development has been achieved in the synthesis, properties, and applications of MXenes. Thus, it has opened up various exciting opportunities to construct advanced MXene‐based nanostructures for ZIBs with excellent specific energy and power. Herein, this review summarizes the advances across multiple synthesis routes, related properties, morphological and structural characteristics, and chemistries of MXenes for ZIBs. The recent development of MXene‐based electrodes is introduced, and electrolytes for ZIBs are elucidated in detail. MXene‐based rocking chair ZIBs, strategies to enhance the performance of MXene‐based cathodes, suppress the dendrites in MXene‐based anodes, and MXene‐based flexible ZIBs are pointed out. A rational design and modification of the MXenes as well as the production of composites with metal oxides exhibits promise in solving issues and enhancing the electrochemical performance of ZIBs. Finally, the present challenges and future prospects for MXene‐based ZIBs are discussed.

Aqueous zinc‐ion battery (AZB) is a promising candidate for next‐generation energy storage owing to inherent safety and low cost. However, AZBs are currently plagued by Zn dendrite growth and undesirable side‐reactions, leading to poor cycling stability and premature failure. To restrain the uncontrollable Zn growth, a unique separator is developed based on polyacrylonitrile/graphene oxide (abbreviated as PG) composite nanofibers, which contain abundance of zincophilicity functional groups to regulate the migration and distribution of Zn2+ ions in the separator. It is demonstrated that the cyano ligands on PG not only facilitate the dehydration of solvated Zn2+ ions prior to deposition, but also form fast lanes to enable homogenous scattering of deposition spots. Benefiting from these features, the PG separator offers a high ionic conductivity of 7.69 mS cm‐1 and a transference number of 0.74 for Zn2+. The Zn||Zn symmetrical cells with PG separators achieve an ultra‐stable cycle life over 13 000 h. Zn||Zn0.27V2O5 full batteries with PG separators retain 71.5% of the original capacity after 2800 cycles at a high current density of 2 A g‐1. This study offers future research directions toward the design of multifunctional separators to overcome the limits of Zn metal anode in AZBs.
