“…Liu et al coated zinc metal anode with graphene oxide (GO) nanosheets via casting method (Fig. 12 c, d) [ 125 ]. The GO nanosheets can not only prevent the Zn intermediates from dissolving into aqueous electrolyte, but also improve the surface electron conductivity, leading to the prolonged cycling life and rate capability.…”

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.

“…That difference equates to competing with Pb-acid batteries (when tapping only 11% DOD Zn ) versus approaching the lower end of single cell-level Li-ion performance for the 100-cycle cell operating at high rate and utilizing 40% DOD Zn . Thus, the impact of reports that show good cycle life, but only exercise their Zn electrode to moderate DOD Zn (10%-15%), 20 can be misinterpreted, especially if presenting the breakthrough in the context of replacing another high energy-density battery chemistry. The lower specific energy of cells operated at light utilization of the zinc anode do not render these results meaningless, but, rather, should steer the authors in articulating the application space in which their breakthroughs pertain.…”

Zinc-based batteries are experiencing a resurgence in interest owing to their promising energy and power metrics, and inherent safety advantages compared with lithium-ion batteries. As scientists worldwide address the remaining obstacles to realizing competitive performance across the family of zinc batteries, the enthusiasm to report new ''breakthroughs'' at the materials or small-device level must be tempered by a realistic understanding of how such improvements will translate to practical energy-storage devices. Framing early-stage results in such a context will advance the prospects of next-generation Zn batteries while avoiding the ''hype cycle'' that has plagued research and development for other energy-storage technologies. Herein, we present guidelines by which to evaluate and report data derived from new electrode formulations and cell components such that the results will directly inform which breakthroughs are technologically relevant to scale up.

“…ZnO lasagna structure has three features: (1) the size of ZnO nanoparticles is smaller than the critical size of passivation; (2) the fabrication of ZnO lasagna anode starts with commercially available ZnO nanoparticles (∼100 nm), and it is compatible with the roll-to-roll process, which is ideal for large-scale manufacturing; (3) GO allows permeation of OH – and water , and prevents loss of Zn active material through blocking bigger Zn(OH) 4 2– . And GO can be partially reduced when soaked into alkaline electrolyte, , which can facilitate electron transfer inside anodes. The transmission electron microscopy (TEM) image (Figure a) and Raman spectra (Figure c) shows the high-quality GO sheets with characteristic peaks of D and G bands at 1363 and 1589 cm –1 , respectively.…”

Rechargeable batteries using aqueous electrolyte have intrinsically low flammability and are promising alternatives to lithium ion batteries for mid-and large-scale energy storages. Among aqueous battery anode materials, zinc metal stands out because of the highest energies (5846 Ah/L volumetric capacity, 3 times the amount of a lithium metal anode) and an operating potential near the lower limit of water stability window. However, the rechargeability of Zn anodes is hindered by passivation and dissolution problems associated with the solid-solute-solid transformation during cycling. Here we solve both problems simultaneously by designing a distinctive nanostructured zinc anode in which 100 nm ZnO nanoparticles are wrapped and segmented by graphene oxide (GO) sheets. The small size of primary ZnO nanoparticles prevents passivation, while the GO wrap and segmentation confine soluble Zn(OH) 4 2− intermediates from escaping. This lasagna-like nanostructured Zn anode measured a high volumetric capacity of 2308 Ah/L and achieved a remarkable capacity retention of 86% after 150 cycles. In contrast, the open-structured ZnO nanoparticle anode, without the protection of GO, completely died after 90 cycles.
