    摘要： The present invention discloses an amine-bromine two electron electrolyte of flow battery and the use thereof, and a flow battery, which belong to the field of flow battery. In the electrolyte, an amino compound with an electron-withdrawing group at the ortho-position of an amino group is used to react with bromine charged to a positive valence so as to form an amine-bromine compound, such that positive-valence bromine is stabilized, and a reversible two-electron transfer reaction from bromine ions to amino compounds is achieved. The amine compounds have different solubilities and produce different voltages depending on their substituent groups, and thus have extensive adjustability and applicability for use in acidic, neutral, and weak alkaline flow battery systems. Flow batteries assembled with the electrolyte prepared using this reaction has the advantages of low cost and high energy density, and can achieve a longer cycle life and higher battery efficiency.
