Abstract

The progress in civilization can be related to the development of newer technological development and associated energy demand to run those systems. The personalized healthcare systems, the depletion of conventional fossil fuel reserve led us to think about alternative energy storage devices. Thus, it is important to develop energy storage materials with the property of good mechanical strength and stability for longer hours. Zn-air batteries (ZAB) show the promises to be an alternative of Li-air batteries for this purpose. ZABs can fulfill our need of stringent requirements such as high energy density, cost-effectiveness and it is safer as compared to Li-ion batteries. The stability of zinc in aqueous and air environments makes ZAB technology more reliable and effective for small to large-scale flexible electronics. To further enhance its efficiency, different scientific materials and methods have been developed over decades, of which this review provides detailed insight into the parameters and mechanisms related to the key components of the ZAB for enhancing the performance of ZAB. We summarized the working mechanism of overall reversible-ZABs and then independently we explained the mechanism and problems associated with cathode, anode, and electrolyte, followed by the current breakthrough related to each. Aspects such as role of optimal e_g occupancy in bifunctional activity, inhibition of zinc dendrite, and gel polymer electrolytes with enhanced conductivity and strength are specifically highlighted. To facilitate a broad discussion among different research communities, important scientific hurdles and their potential solution related to R-ZABs are also summarized.

可充电锌-空气电池中的化学成分：机理概述

文明的进步与更新技术的发展以及运行这些系统的相关能源需求有关。个性化的医疗保健系统、传统化石燃料储备的枯竭促使我们思考替代能源存储设备。因此，开发具有良好机械强度和长时间稳定性的储能材料非常重要。为此，锌空气电池（ZAB）有望成为锂空气电池的替代品。与锂离子电池相比，锌空气电池能满足我们对高能量密度、成本效益和安全性的严格要求。锌在水和空气环境中的稳定性使 ZAB 技术在小型到大型柔性电子产品中更加可靠和有效。为了进一步提高其效率，几十年来人们开发了不同的科学材料和方法，本综述将详细介绍与 ZAB 关键部件相关的参数和机制，以提高 ZAB 的性能。我们总结了整体可逆ZAB的工作机理，然后分别解释了阴极、阳极和电解质的相关机理和问题，随后介绍了目前与每个部件相关的突破。我们还特别强调了最佳eg 占有率在双功能活性中的作用、锌枝晶抑制以及具有更强导电性和强度的凝胶聚合物电解质等方面的问题。为了便于不同研究界进行广泛讨论，还总结了与 R-ZAB 有关的重要科学障碍及其潜在解决方案。

期刊介绍： Catalysis Today focuses on the rapid publication of original invited papers devoted to currently important topics in catalysis and related subjects. The journal only publishes special issues (Proposing a Catalysis Today Special Issue), each of which is supervised by Guest Editors who recruit individual papers and oversee the peer review process. Catalysis Today offers researchers in the field of catalysis in-depth overviews of topical issues. Both fundamental and applied aspects of catalysis are covered. Subjects such as catalysis of immobilized organometallic and biocatalytic systems are welcome. Subjects related to catalysis such as experimental techniques, adsorption, process technology, synthesis, in situ characterization, computational, theoretical modeling, imaging and others are included if there is a clear relationship to catalysis.
