Abstract

Seawater metal-air batteries (SMABs) are promising energy storage technologies for their advantages of high energy density, intrinsic safety, and low cost. However, the presence of such chloride ions complex components in seawater inevitably has complex effects on the air electrode process, including oxygen reduction and oxygen evolution reactions (ORR and OER), which requires the development of highly-active chloride-resistant electrocatalysts. In this review, we first summarized the developing status of various types of SMABs, explaining their working principle and comparing the battery performance. Then, the reported chlorine-resistant electrocatalysts were classified. The composition and structural design strategies of high-efficient chlorine-resistant ORR/OER electrocatalysts in seawater electrolytes were comprehensively summarized. Finally, the main challenges to be overcome in the commercialization of SMABs were discussed.

海水金属-空气电池的概念、结构及进展

海水金属空气电池(SMABs)具有能量密度高、本质安全、成本低等优点，是一种很有前途的储能技术。然而，海水中氯离子络合组分的存在不可避免地会对空气电极过程产生复杂的影响，包括氧还原和析氧反应(ORR和OER)，这就需要开发高活性的耐氯电催化剂。在本文中，我们首先总结了各种类型的SMABs的发展现状，解释了它们的工作原理，并比较了电池的性能。然后对已报道的耐氯电催化剂进行了分类。综述了海水电解质中高效耐氯ORR/OER电催化剂的组成及结构设计策略。最后，讨论了中小企业商业化需要克服的主要挑战。

期刊介绍： Superlattices and Microstructures has continued as Micro and Nanostructures. Micro and Nanostructures is a journal disseminating the science and technology of micro-structures and nano-structures in materials and their devices, including individual and collective use of semiconductors, metals and insulators for the exploitation of their unique properties. The journal hosts papers dealing with fundamental and applied experimental research as well as theoretical studies. Fields of interest, including emerging ones, cover: • Novel micro and nanostructures • Nanomaterials (nanowires, nanodots, 2D materials ) and devices • Synthetic heterostructures • Plasmonics • Micro and nano-defects in materials (semiconductor, metal and insulators) • Surfaces and interfaces of thin films In addition to Research Papers, the journal aims at publishing Topical Reviews providing insights into rapidly evolving or more mature fields. Written by leading researchers in their respective fields, those articles are commissioned by the Editorial Board.
