Worldwide demand for oil, coal, and natural gas has increased recently because of odd weather patterns and economies recovering from the pandemic. By using these fuels at an astonishing rate, their reserves are running low with each passing decade. Increased reliance on these sources is contributing significantly to both global warming and power shortage problems. It is vital to highlight and focus on using renewable energy sources for power production and storage. This review aims to discuss one of the cutting-edge technologies, metal-air batteries, which are currently being researched for energy storage applications. A battery that employs an external cathode of ambient air and an anode constructed of pure metal in which an electrolyte can be aqueous or aprotic electrolyte is termed as a metal-air battery (MAB). Due to their reportedly higher energy density, MABs are frequently hailed as the electrochemical energy storage of the future for applications like grid storage or electric car energy storage. The demand of the upcoming energy storage technologies can be satisfied by these MABs. The usage of metal-organic frameworks (MOFs) in metal-air batteries as a bi-functional electrocatalyst has been widely studied in the last decade. Metal ions or arrays bound to organic ligands to create one, two, or three-dimensional structures make up the family of molecules known as MOFs. They are a subclass of coordination polymers; metal nodes and organic linkers form different classes of these porous materials. Because of their modular design, they offer excellent synthetic tunability, enabling precise chemical and structural control that is highly desirable in electrode materials of MABs.
由于异常的天气模式以及经济从疫情中复苏，近期全球对石油、煤炭和天然气的需求有所增加。以惊人的速度使用这些燃料，其储量每过十年就会减少。对这些能源的依赖增加，正在极大地加剧全球变暖和电力短缺问题。突出并专注于使用可再生能源进行发电和储能至关重要。本综述旨在讨论一种前沿技术——金属空气电池，目前它正被研究用于储能应用。一种采用环境空气作为外部阴极和由纯金属构成阳极，其中电解质可以是水性或非质子电解质的电池被称为金属空气电池（MAB）。据报道，由于其较高的能量密度，金属空气电池常被誉为未来用于电网储能或电动汽车储能等应用的电化学储能方式。这些金属空气电池能够满足即将到来的储能技术的需求。在过去十年中，金属有机框架（MOF）在金属空气电池中作为双功能电催化剂的应用得到了广泛研究。与有机配体结合形成一维、二维或三维结构的金属离子或阵列构成了被称为MOF的分子家族。它们是配位聚合物的一个子类；金属节点和有机连接体形成了这些不同类型的多孔材料。由于其模块化设计，它们具有出色的合成可调性，能够实现精确的化学和结构控制，这在金属空气电池的电极材料中是非常理想的。
