海水电池是一种独特的储能系统，可直接利用海水作为电能和化学能的转化源，实现可持续的可再生能源存储。该技术是锂离子电池的可持续且具有成本效益的替代品，受益于海水中富含钠作为电荷转移离子。在过去的几年里，研究已经显着改善和修改了这种电池的性能。然而，在未来的研究中，该技术的基本限制仍有待克服，以使这种方法更加可行。缺点包括阳极材料的降解或在盐水中的膜稳定性有限，导致电化学性能低和库仑效率低。海水电池的使用超过了储能的应用。海水电池运行所固有的离子的电化学固定化也是直接海水淡化的有效机制。高充电/放电效率和能量回收使海水电池成为一种有吸引力的水修复技术。本文回顾了海水电池组件以及用于评估其储能和海水淡化性能的参数。还介绍了克服稳定性问题和低电压效率的方法。最后，概述了潜在的应用，特别是在海水淡化技术方面。高充电/放电效率和能量回收使海水电池成为一种有吸引力的水修复技术。本文回顾了海水电池组件以及用于评估其储能和海水淡化性能的参数。还介绍了克服稳定性问题和低电压效率的方法。最后，概述了潜在的应用，特别是在海水淡化技术方面。高充电/放电效率和能量回收使海水电池成为一种有吸引力的水修复技术。本文回顾了海水电池组件以及用于评估其储能和海水淡化性能的参数。还介绍了克服稳定性问题和低电压效率的方法。最后，概述了潜在的应用，特别是在海水淡化技术方面。

Dual-Use of Seawater Batteries for Energy Storage and Water Desalination

Seawater batteries are unique energy storage systems for sustainable renewable energy storage by directly utilizing seawater as a source for converting electrical energy and chemical energy. This technology is a sustainable and cost-effective alternative to lithium-ion batteries, benefitting from seawater-abundant sodium as the charge-transfer ions. Research has significantly improved and revised the performance of this type of battery over the last few years. However, fundamental limitations of the technology remain to be overcome in future studies to make this method even more viable. Disadvantages include degradation of the anode materials or limited membrane stability in aqueous saltwater resulting in low electrochemical performance and low Coulombic efficiency. The use of seawater batteries exceeds the application for energy storage. The electrochemical immobilization of ions intrinsic to the operation of seawater batteries is also an effective mechanism for direct seawater desalination. The high charge/discharge efficiency and energy recovery make seawater batteries an attractive water remediation technology. Here, the seawater battery components and the parameters used to evaluate their energy storage and water desalination performances are reviewed. Approaches to overcoming stability issues and low voltage efficiency are also introduced. Finally, an overview of potential applications, particularly in desalination technology, is provided.
