“…Composite nanostructure design is deemed as an effective strategy to restrict dendrite growth, suppress the formation of by-products, and constrain the corrosion of zinc anode [ 116 ]. For example, Yan et al designed lasagna-like nanostructured Zn anode, in which ZnO nanoparticles are wrapped with graphene oxide nanosheets [ 117 ]. The composite anode can provide much higher volumetric capacity and capacity retention when compared with pure ZnO.…”

HIGHLIGHTS• The recent progress about zinc-ion batteries was systematically summarized in detail, including the merits and limits of aqueous and nonaqueous electrolytes, various cathode materials, zinc anode, and solid-state zinc-ion batteries.• Current challenges and perspectives to future research directions are also provided. ABSTRACT The increasing demands for environmentally friendly grid-scale electric energy storage devices with high energy density and low cost have stimulated the rapid development of various energy storage systems, due to the environmental pollution and energy crisis caused by traditional energy storage technologies. As one of the new and most promising alternative energy storage technologies, zinc-ion rechargeable batteries have recently received much attention owing to their high abundance of zinc in natural resources, intrinsic safety, and cost effectiveness, when compared with the popular, but unsafe and expensive lithium-ion batteries. In particular, the use of mild aqueous electrolytes in zinc-ion batteries (ZIBs) demonstrates high potential for portable electronic applications and large-scale energy storage systems.Moreover, the development of superior electrolyte operating at either high temperature or subzero condition is crucial for practical applications of ZIBs in harsh environments, such as aerospace, airplanes, or submarines. However, there are still many existing challenges that need to be resolved. This paper presents a timely review on recent progresses and challenges in various cathode materials and electrolytes (aqueous, organic, and solid-state electrolytes) in ZIBs. Design and synthesis of zinc-based anode materials and separators are also briefly discussed.

“…Typically, a 3D Zn foam structure was used to alleviate passivation issues by increasing specific surface area. [24,25] In recent years, many interests [26][27][28] have focused on the application of graphene materials with high specific surface area to improve the stability of Zn metal anode. In addition, several sealed structures, [16,29,30] such as ZnO@TiNxOy nanorod, [16] ZnO@C nanoparticles [29] et al, were proposed to avoid the dissolution issue.…”

Rechargeable alkaline Zn–air batteries (ZABs) are attracting extensive attention owing to their high energy density and environmental friendliness. However, the dilemma of Zn anode, composed of ineluctable passivation and dissolution problems, severely hinders the discharge and cycling performance of the battery. Herein, the authors propose a chemical buffer layer coated on Zn metal (CBL@Zn) anode, in which ZnO nanorods are uniformly dispersed in graphene oxide (GO), to improve the reversibility of Zn↔ZnO electrochemical conversion process. Benefiting from the cooperative effect of ZnO nanorods’ nuclei role and GO's adsorption affinity, the electrochemical precipitation–dissolution behavior of insulated ZnO is chemically regulated and the Zn(OH)42− ions are effectively confined in the chemical buffer layer. Therefore, the symmetrical CBL@Zn‐CBL@Zn coin cell achieves a superior stability of 100 cycles with quite low overpotential (30 mv). When paired with commercial catalysts to assemble alkaline ZABs for practical use, an ultra high depth of discharge (DODZn) >98% and excellent 450‐h long‐term cycling performance are realized. This chemical buffer strategy can potentially provide a new insight for developing other highly reversible alkaline Zn‐metal batteries.
