“…Synthesis of composites of these oxide materials using various conducting carbons such as reduced graphene oxide (rGO), carbon nanotubes (CNTs), porous carbon, and heteroatom doped carbon and doping of the metal oxides with transition metals is proved to be an effective strategy to mitigate these issues. [42,[205][206][207][208][209][210][211][212][213] The ZIB performance of these composites is superior to that of the bare MnO 2 . The spherical-shaped composite material based on α-MnO 2 nanofiber and highly conductive CNT, obtained by room temperature precipitation followed by calcination and spray-granulation, delivers a decent capacity of 296 mAh g À 1 , high rate capability and ultra-long cycling lifespan of 10 000 cycles with 96 % retention of capacity.…”

The growing demand for the renewable energy storage technologies stimulated the quest for efficient energy storage devices. In recent years, the rechargeable aqueous zinc-based battery technologies are emerging as a compelling alternative to the lithium-based batteries owing to safety, eco-friendliness, and cost-effectiveness. Among the zinc-based energy devices, rechargeable zinc-ion batteries (ZIBs) are drawing considerable attention. However, they are plagued with several issues, including cathode dissolution, dendrite formation, etc.. Despite several efforts in the recent past, ZIBs are still in their infant stages and have yet to reach the stage of large-scale production. Finding stable Zn 2 + intercalation cathode material with high operating voltage and long cycling stability as well as dendrite-free Zn anode is the main challenge in the develop-ment of efficient zinc-ion storage devices. This Review discusses the various strategies, in terms of the engineering of cathode, anode and electrolyte, adopted for improving the charge storage performance of ZIBs and highlights the recent ZIB technological innovations. A brief account on the history of zinc-based devices and various cathode materials tested for ZIB fabrication in the last five years are also included. The main focus of this Review is to provide a detailed account on the rational engineering of the electrodes, electrolytes, and separators for improving the charge storage performance with a future perspective to achieving high energy density and long cycling stability and large-scale production for practical application.

“…However, due to strong electrostatic interaction with divalent zinc ion the vanadate cathode has slow kinetics and poor cyclic stability. Deng and colleagues ( Lin et al, 2020 ) constructed a novel vanadate oxide structure and successfully designed a defection-rich (V 6 O 13 -δ)/C nanovortex to prepare a fibrous flexible DVOC/SWNT@CNTF electrode (SWNT: single-walled carbon nanotube; Carbon nanotube fiber CNTF was prepared). Based on SWNT network and substrate are provided based on CNTF bicontinuous electronic path, promoted the fast dynamics and excellence rate capability ( Figures 6F–H ).…”

Flexible zinc batteries have great potential in wearable electronic devices due to their high safety, low cost, and environmental friendliness. In the past few years, a great deal of work on flexible zinc batteries has been reported, with exciting results. Therefore, many solutions have been proposed in electrode design and electrolyte preparation to ensure the desired flexibility without sacrificing the capacity. This paper reviews the recent progress of flexible zinc batteries. We discuss the differences between various anode materials, cathode materials, and electrolytes, introduce the differences of electrode preparation methods of active materials on flexible substrates and their influence on the performance of the battery. Finally, the challenges and future research trends of flexible zinc batteries in capacity and mechanical properties are pointed out.

“…In addition to the above carbon-based functional materials, some researchers directly decorated cathode materials with low cost functionalized carbon [70]. Typically, the zeolitic imidazolate framework (ZIF)-8-derived N-doped carbon coating MnOx (MnOx@N-C) nanorods cathode was studied by Sun et al [70][71][72]. The porous conductive carbon network increased the conductivity of the whole cathode and ensured the sufficient contact between MnOx and electrolyte (Figs.…”

Aqueous rechargeable zinc ion batteries (ARZIBs) have received unprecedented attention owing to the low cost and high-safety merits. However, their further development and application are hindered by the issues of electrodes such as cathode dissolution, zinc anode dendrite, passivation, as well as sluggish reaction kinetics. Designing heterostructure electrodes is a powerful method to improve the electrochemical performance of electrodes by grafting the advantages of functional materials onto the active materials. In this review, various modified heterostructure electrodes with optimized electrochemical performance and wider applications are introduced. Moreover, the synergistic effect between active materials and functional materials are also in-depth analyzed. The specific modification methods are divided into interphase modification (electrode-electrolyte interphase and electrode-current collector interphase) and structure optimization. Finally, the conclusion and future perspective on the optimization mechanism of functional materials, and the cost issue of practical heterostructure electrodes in ARZIBs are also proposed. It is expected that this review can promote the further development of ARZIBs towards practical utility.
