电解液是全钒液流电池最重要的组成部分之一，其性质除了影响电池的整体成本外，还将影响电池的性能和行为。钒以几种氧化态存在，具有显著不同的半电池电位，可以产生实际的电池电压。因此，可以在两个半电池中使用相同的元素，从而消除所有其他液流电池化学中固有的交叉污染问题。电解质性质随支持电解质成分、荷电状态和温度而变化，这将影响钒电池在实际应用中的特性、行为和性能。本文综述了钒电池电解液在不同条件下的物理性质和特性，并描述了一些已开发的用于生产钒氧化还原液流电池应用的钒电解液的加工方法。
The electrolyte is one of the most important components of the vanadium redox flow battery and its properties will affect cell performance and behavior in addition to the overall battery cost. Vanadium exists in several oxidation states with significantly different half‐cell potentials that can produce practical cell voltages. It is thus possible to use the same element in both half‐cells and thereby eliminate problems of cross‐contamination inherent in all other flow battery chemistries. Electrolyte properties vary with supporting electrolyte composition, state‐of‐charge, and temperature and this will impact on the characteristics, behavior, and performance of the vanadium battery in practical applications. This Review provides a broad overview of the physical properties and characteristics of the vanadium battery electrolyte under different conditions, together with a description of some of the processing methods that have been developed to produce vanadium electrolytes for vanadium redox flow battery applications.
