Harvesting energy from natural resources is of significant interest because of their abundance and sustainability. Seawater is the most abundant natural resource on earth, covering two‐thirds of the surface. The rechargeable seawater battery is a new energy storage platform that enables interconversion of electrical energy and chemical energy by tapping into seawater as an infinite medium. Here, an overview of the research and development activities of seawater batteries toward practical applications is presented. Seawater batteries consist of anode and cathode compartments that are separated by a Na‐ion conducting membrane, which allows only Na⁺ ion transport between the two electrodes. The roles and drawbacks of the three key components, as well as the development concept and operation principles of the batteries on the basis of previous reports are covered. Moreover, the prototype manufacturing lines for mass production and automation, and potential applications, particularly in marine environments are introduced. Highlighting the importance of engineering the cell components, as well as optimizing the system level for a particular application and thereby successful market entry, the key issues to be resolved are discussed, so that the seawater battery can emerge as a promising alternative to existing rechargeable batteries.

海水可充电电池-从概念到应用

由于自然资源的丰富性和可持续性，从自然资源中获取能量备受关注。海水是地球上最丰富的自然资源，覆盖了三分之二的地表。海水可充电电池是一个新的储能平台，它可以通过利用海水作为无限介质来实现电能和化学能的相互转换。在此，将概述海水电池在实际应用中的研究和开发活动。海水电池由阳极室和阴极室组成，阳极室和阴极室之间由Na离子导电膜隔开，该膜仅允许Na ⁺离子在两个电极之间的传输。涵盖了这三个关键组成部分的作用和缺点，以及在以前的报告的基础上电池的开发概念和操作原理。此外，还介绍了用于大规模生产和自动化的原型生产线以及潜在的应用，特别是在海洋环境中。强调了工程设计电池组件的重要性，以及针对特定应用优化系统级别并由此成功进入市场的重要性，并讨论了需要解决的关键问题，从而使海水电池可以作为现有可充电电池的有前途的替代品出现。
