摘要 相关文章 Metrics 全文: PDF(1990 KB)   摘要: 双极板是全钒液流电池（VRFB）核心集流与隔离部件，其耐蚀稳定性直接影响电池欧姆内阻、能量转换效率与长期循环使用寿命。针对全钒液流电池复杂酸性服役环境下双极板多机制腐蚀失效问题，本文构建多腐蚀环境对比评价体系，分别开展单电池实际服役后、浓硫酸加速腐蚀处理后、五价钒电解液加速腐蚀处理后的三类双极板评测实验，系统探究双极板在不同腐蚀介质中的腐蚀演化规律，明晰电化学性能衰退与电池运行性能劣化的内在作用机理。结果证实，电池实际运行工况下正负极的双极板存在腐蚀差异，正极高电位氧化腐蚀劣化程度远高于负极；浓硫酸环境仅对石墨基体产生轻度刻蚀，一定程度活化极板表面；五价钒电解液体系兼具强酸腐蚀与钒离子界面氧化耦合作用，对双极板界面结构破坏作用最强，界面劣化现象突出。该研究厘清了全钒液流电池双极板在差异化腐蚀环境下的腐蚀演化规律与性能衰减机制，可为双极板耐蚀改性开发、介质环境适配评价及长寿命全钒液流电池结构优化设计提供试验数据与理论参考。 关键词 ： 全钒液流电池,  双极板,  腐蚀行为,  电化学性能     Abstract：As the core current-collecting and separating component of vanadium redox flow battery (VRFB), bipolar plates dominate the corrosion resistance stability, which directly determines the ohmic internal resistance, energy conversion efficiency and long-term cycle life of batteries. Aiming at the multi-mechanism corrosion failure of bipolar plates under the complex acidic service environment of VRFB, a comparative evaluation system with multiple corrosion environments was established in this work. Three types of characterization experiments on bipolar plates were carried out, including tests on bipolar plates after actual single-cell service, after accelerated corrosion treatment in concentrated sulfuric acid and after accelerated corrosion treatment in pentavalent vanadium electrolyte, to systematically investigate the corrosion evolution laws of bipolar plates in different corrosive media, and reveal the internal mechanism between electrochemical performance degradation and battery performance deterioration. The results show that obvious corrosion differences exist between positive and negative bipolar plates under practical operating conditions, and the degradation degree induced by high-potential oxidation corrosion on positive plates is far severer than that on negative plates. Concentrated sulfuric acid only slightly etches graphite matrix and activates the plate surface to a certain extent. The pentavalent vanadium electrolyte system exhibits coupled effects of strong acid corrosion and interfacial oxidation of vanadium ions, causing the most severe damage to the interfacial structure of bipolar plates with prominent interface deterioration. This study clarifies the corrosion evolution rules and performance attenuation mechanisms of VRFB bipolar plates under distinct corrosive environments, and provides experimental data and theoretical references for the development of corrosion-resistant modification on bipolar plates, evaluation of medium environmental adaptability, and structural optimization design of long-lifespan vanadium redox flow batteries.
