Abstract

Hydrogen–bromine redox flow batteries (HBFBs) offer significant advantages in energy storage, including high energy capacity, efficient round-trip conversion, and low cost, positioning them as optimal solutions for grid applications. However, HBFBs are susceptible to issues such as self-discharge, the bromine shuttle effect, high Br2 vapor pressure, poisoning, and corrosion. Bromine complexing agents (BCAs) have been employed to mitigate these challenges, albeit with drawbacks such as reduced electrolyte conductivity, catalyst site blockage, and diffusion limitation. This review explores the impact of BCAs on the performance of HBFBs, focusing on cell structures such as electrolytes, membranes, and electrodes. Recent research progress in membrane materials and Pt catalysts is summarized to address these issues, and future prospects and challenges for high-performance HBFBs development are discussed.

溴络合剂和电池结构对氢-溴氧化还原液流电池性能的影响
氢溴氧化还原液流电池(hbbbs)在能量存储方面具有显著的优势,包括高能量容量、高效的往返转换和低成本,使其成为电网应用的最佳解决方案。然而,hbbbs容易受到自放电、溴穿梭效应、高Br2蒸气压、中毒和腐蚀等问题的影响。溴络合剂(bca)已被用于缓解这些挑战,尽管存在诸如降低电解质导电性、催化剂位点堵塞和扩散限制等缺点。这篇综述探讨了bca对hbbbs性能的影响,重点是电解质、膜和电极等细胞结构。本文综述了近年来膜材料和铂催化剂的研究进展,并对高性能hbbbs的发展前景和挑战进行了展望。
